0:26
the new technology that's coming out of the iPhone 6s. Hi everyone, and welcome back to C Sharp Corner MVP show
1:04
And as always, I'm your host, Simon. And we are back. We took a break
1:08
from the C Sharp Corner MVP show for about, I would say, in December
1:12
and November and December. But I'm so happy that we are back once again
1:16
And if you're someone who is joining us for the very first time, C Sharp Corner MVP show is a show
1:20
where we feature our C Sharp Corner MVPs. And those are the ones who are
1:24
the community leaders. They contribute to the community. They are very active
1:28
They're always helpful. They contribute in many ways. Some people write articles
1:32
Some make videos. Some reply in forums. Some write books. Some do
1:36
events. Some do speaking at events. And speaking at events reminds me that today we will
1:42
be joined by MD Sarfaraj, who is a rock star in India
1:46
If you're someone who works in the Flutter community or you are active
1:50
you will always see MD Sarfaraj over there. He likes to go by
1:54
his acronym MD. He's very active on LinkedIn, Twitter, wherever I see. If there's
2:02
any Flutter event happening or if there's any Flutter blog, on my news feed
2:08
anything around Flutter comes from MD Sarfaraj. So I'm really, really excited that I'm getting to host him
2:14
I think second or third time on this show. And guess what he's going to talk about
2:20
Flutter. So without any further ado, let's bring our guest today. MD. MD, welcome
2:26
to the C Sharp Corner MVP show. Yeah. Hi, Saman. Thank you for inviting
2:30
me on C Sharp Corner MVP show. Yeah. When you were giving such a nice introduction
2:36
I was thinking like, is it really me who is working so much? Yeah
2:42
You do, MD. I mean, when you like someone's LinkedIn post or when you share a blog
2:48
when you talk about, hey, this is the new feature of Flutter, when you share it on
2:52
LinkedIn or Twitter, people may not like it, but people like me, we see
2:56
it, right? So that is one thing that I, whenever I think about Flutter, I think about
3:02
you in India, few other folks, but you are way more close to me than anyone else
3:08
So thank you for accepting the invitation to be on the show. And
3:12
MD, tell me, how has life been and where are you actually joining us today from
3:16
Yeah, it's going very good, Simon, and currently I'm in Hyderabad. So I'm joining
3:22
Hyderabad today, yeah. That's nice. That's nice. All right. So we won't
3:26
take much of your time. I know you're going to talk about Code Push for Flutter
3:30
which really helps people to go ahead and deploy their applications smoothly and easily
3:34
I'm going to let you take over the stage. So please feel free to go ahead
3:38
and share your screen. And everyone who's watching, if you have any questions related to Flutter
3:42
generally Flutter or around the session, MD is always there. You can
3:48
ask your question in the comment section and we will take them towards
3:52
the end of the session. Okay, Simon. I'm going to share my screen
3:58
Yeah, please go ahead and add it to the stream when I see it
4:06
Yeah, can you see my screen? Yeah, I think you're inside the stream once you
4:14
go back from there to some other screen. Once you, yeah, I can see your
4:20
slides. Yes, that's perfect. Everybody else can see your screen and the session's all yours
4:26
Yeah, so thank you, Simon. So, hello everyone and thank you for joining this session
4:32
Okay, so my name is MD Sarraj and currently I'm working as a mobile application
4:38
developer in AppSys. Okay, and apart from my work, I like to write blogs and articles
4:44
on CSR Corner, and apart from tech, I love to listen to music and reading
4:52
books. So, yeah, these are my hobbies. You can connect me on LinkedIn and you can follow me
4:58
on Twitter. So, today my topic is code push for Flutter application. So
5:06
our agenda is, first we will try to understand what is code push and after that
5:12
we will see what are the importance of code push in Flutter application
5:16
Then we will see what is Sorbet and we will see a live demo, okay, how
5:22
we can configure Sorbet in our Flutter application and at the last we will open
5:28
question and answer. So, without further ado, let's start. So, what is code push? So
5:36
for example, you are having an app live on your Play Store
5:42
and App Store, okay, and you are suddenly facing a bug over there, okay, you want
5:48
to fix that bug, okay. So, to fix that bug you have to send an update
5:54
to Play Store and App Store and their team will first review that
6:00
update, okay, then they will make it live, then user can update your app, okay
6:06
So, it is somewhat lengthy process. You have to wait for the review
6:10
and then your update will get live. But, you have to fix those issues as soon
6:18
as possible. So, code push in this scenario, code push comes into the picture where you
6:24
can send the update to end user device without depending on the Google Play Store, App Store
6:32
reviewing process. So, you can skip the review for small updates and you can
6:38
push the small updates to end user device directly. And why we need Flutter
6:48
code push for the Flutter app? So, basically when you are pushing small updates to
6:56
user, okay, without depending on the App Store and Play Store reviewing process
7:02
you can continuously send the update and you can seek the feedback from the user if there are
7:08
any production issues. You can fix as soon as possible, okay, and
7:14
you can do some small feature changes, okay, and you can roll out those changes directly
7:22
to end user device. So, these are the features which code push is providing
7:30
So, what is Sorbot? So, Sorbot is a platform which is managing the
7:36
code push for the Flutter application and it is developed by one of the Flutter team
7:42
members, okay. So, actually it is an open source project. So, you can
7:48
go and check that out, okay. So, now we will see how we can
7:54
do the... how we can configure the Sorbot in our application and how can we roll out
8:02
an update to end user, okay. So, first of all, you have to
8:06
search Sorbot in your search engine and you have to go to sorbot.dev So
8:14
currently Sorbot is using Google login, okay. So, you can login to any of
8:20
your Google accounts, okay. Once you are logged in, okay. So, I am going to use my Google
8:28
account. Once you are logged in, you will see this installation process. It is very simple, just
8:36
one line of command, okay. So, if you are a Mac user, you have to
8:40
copy this command and you have to open the terminal and you have to run this command
8:44
and Sorbot CLI will get installed in your machine. And if you are a Windows user
8:50
then you have to open the PowerShell and you have to run this command and
8:54
it will install the Sorbot CLI. Once it is, installation is done
9:00
you have to type this command sorbot login and it will give you an authentication link
9:06
You have to click on that link and you have to authenticate yourself
9:10
So, once you will get authenticated, now you can use the further
9:18
process. So, first I will go and I will create a Flutter project. So
9:26
I have a folder on desktop, which name is Sorbot demo. So
9:32
there I am going to create a Flutter project. To create a
9:36
Flutter project, we have a simple command, flutter create and project name. So
9:42
for this demo, I am going to give a name sorbot demo. So
9:52
I have a sorbot Flutter demo. And then you have to hit
10:02
enter and you have to wait for couple of minutes to complete the process. Yeah, it's done. Okay
10:12
After that, you have to open the project in any of the code editor
10:16
For me, Android stereo is more comfortable for me. If you are okay with
10:22
VS code, you can use that, not a problem. So, I will go and open the project, which
10:28
I just created now. So, here is my project. I will open this
10:38
So, Android is taking some time to load the resources. Let it load
10:52
Yeah. So, once it
11:02
all the resources loading is done from Android stereo side, we have to open the terminal
11:08
and you have to type the command sorbot login. So, I am already logged in
11:16
So, it is saying like you are already logged in. Okay. So, if you are not logged in
11:24
it will give you a link. You have to click on that link and it will authenticate
11:28
To configure the sorbot in our project, okay, we have to type the command
11:34
sorbot init. Okay. And it will take some
11:44
time to configure the sorbot in your project. Okay. And it is asking
12:02
name of the project. So, I want to continue with the same name
12:08
So, I will just hit enter. And yeah
12:20
So, one more thing. Sorbot requires internet permission. So, if you have not added your
12:28
internet permission, it will automatically add or it's better you can add. So, you have to go to Android
12:34
folder under app SRC main. There you will see Android XML file. Okay. Android
12:42
manifest file. There you have internet permission. So, I forgot to add this permission
12:48
but not a problem. Here you can see like sorbot already added. Okay
12:54
After that, you have to create a build for the Android platform. Okay. So
13:04
when we are creating, suppose when we are going to release our app on
13:08
Play Store, we have to make an app bundle. Okay. In the same way, here also
13:12
you have to make the app bundle. Okay. Or release. So, you have to type the command sorbot release
13:22
Android. Okay. Before that, if I come back here on console and if you will
13:28
replace it, you will see your app. You can see your app is
13:32
here. Okay. Now we are making the release. So, you will see the
13:36
release version over here. And once you will configure the sorbot in your project, you will get a sorbot.yml
13:44
file and this yml file will contains app ID and this app ID is
13:50
for the sorbot server. So, they will get to know your app
13:56
through this app ID. So, currently I'm making an Android build. Okay
14:02
So, it will take some time. So, we have to wait for couple of minutes
14:12
Okay. And
14:44
yes, one more thing I would like to say. Yeah. So, yeah, it's done. So, you can
14:52
see like your app ID here. And you can see the version and version number. Okay
15:04
So, you can see the version number. Okay. And you can see the
15:14
version and version code. So, you can verify the version and version
15:18
from pubspec.yml file and yeah, here is your version and version code. So, yeah, both are similar
15:26
And it is making the release build for this platform. I'm 64, 32
15:32
and 86 and 64 width. And currently my flutter version is this is the
15:38
is this why it didn't Yeah. So, it is saying
15:56
build is created and you can go here actually under build folder
16:04
app outputs bundle you will get a release ADB file. Okay. So, you have
16:12
to upload this ADB file in your play store. So, and they will review it and they will make your
16:20
app live. But currently I'm not going to do that. Because it is a very lengthy
16:26
process. So, to verify it locally. Okay. So, what we're giving us a
16:32
facility to verify your release app. Okay. In locally through a command. Okay. So, before that
16:40
once I will go and replace here, you will see and write
16:46
releases here. Okay. And the version and version came here. Okay. So
16:52
now I will try to install this current release in my local emulator. Okay
16:58
Through a sort of a command. Okay. So, we can do that
17:02
Just you have to type preview. Before that, you have to make sure you are connected with
17:10
ADB devices. So, as you can see, I have currently one emulator is running
17:18
Okay. One emulator is running. So, I will type the command show but preview
17:24
and it will download the, it will ask which preview would you
17:30
like to run. So, I am having only one at the moment. So, I will go to this
17:34
Okay. And it will download your app from the server to your emulator. So, ... ... ... ... ... ..
17:56
So, as you can see, it's downloaded and installing my app into my emulator
18:06
and this current app is downloaded from the server. Okay. Now, suppose I
18:16
want to change the theme of my app. Okay. And I want
18:20
to roll out this update to user. Okay. And I don't want
18:26
to depend on the place where the app is to review process. So, let's
18:30
do that. So, here currently the color is pink is deep purple
18:36
I will change this to deep orange. Okay. For example, let's change this
18:42
to deep orange. Okay. And I have to send this patch to show but
18:50
server. Okay. So, to send the patch we have to type the command
18:56
show but patch and platform name. So, I am sending for the invite. So, I will
19:02
write invite. Okay. Patch is nothing but the small changes which you are doing
19:06
in your code and sending it to show but server for the update
19:20
So, it will take some time to roll out your patch to show but server and all
19:26
the user device. So, just wait for some time. Yeah. And
19:56
while this is sending the patch. Okay. I would like to say this iOS
20:06
in alpha mode, alpha version so but alpha version. Okay. So, iOS is little bit slow at the
20:12
moment and they are working very hard to make the iOS stable
20:16
Again, it will ask you all the information are connected or not. So, it seems
20:22
everything is correct for me. So, I will type yes and it will roll out the
20:28
patch. Okay. So, it will give you a message. Patch is published
20:32
Okay. So, now let's do one thing. Here I will go and close this app. Okay
20:44
Again, I will open this app. Okay. Just look at this log. Okay. And here
20:52
it is checking for the update. Just wait a minute. Yeah. Here you can see in the log update
21:06
installed it. Okay. So, there was an update in the server as
21:12
you can see like if I refresh the server console. Yeah. You can see here
21:20
I just pushed one patch. So, you can see patch one is
21:24
there. Okay. But here I am not seeing any changes. So, I have to close it again
21:32
Okay. Because the update is installed but when you have to see the update, you have to
21:38
reopen it again. So, when I will open it again, you will see the
21:42
changes. The changes which I made in the color you see. Okay
21:52
So, yeah. Now you can see the app color is changed. Okay
21:58
So, this is all what Sorbot is. So, I wanted to say like Sorbot
22:06
iOS in alpha version currently. Okay. So, it will take some time to get the stable but Android
22:12
is stable. Okay. And when you will click on this app, you can see like you can add
22:18
more collaborators. Okay. So, they are having some plans and paid plans. So, according to
22:24
your plans, you have to collaborators are coming in the premium version
22:30
Okay. And you can see all the patches here and you can see the insights here. How many
22:36
patches get installed. Okay. So, they are having all these good charts
22:42
in their platform. Okay. And you can follow the documentation here. Okay. So
22:52
now the question is Sorbot is like it is following the Google Play Store
23:00
and App Store privacy and policy. So, yes, it is following the privacy of
23:06
App Store and Play Store and it is we can push the update over
23:12
here. Okay. It is like legal. Okay. And it is following the privacy to
23:18
know more about privacy they kept it over here in their documentation. So
23:30
this you have to go in FAQ. Okay. And here you will find
23:38
Yeah, that's the Google Play Store guidelines. And you can read the guidelines
23:48
here. Okay. Or you can directly go to Google Play Store guidelines and you can read all the
23:52
guidelines. So, they are following the guidelines. So, yeah, that's it. If there is any question, please
23:58
feel free to ask. I will stop sharing my screen. Yeah, Simon
24:08
That was really neat. Yeah, that was good. There are always some
24:16
into the demo and when it works with the Android Studio, it kind of always lags
24:20
We don't have any question at this instance. MD, but MD, I know you work with Flutter
24:26
in the development. So, is this the same tool that you also use when you
24:30
have to work in your production environment? So, yeah. Good question, Simon. Actually
24:36
take an example, you are having an app, okay, and that app is
24:40
serving millions of users. And suddenly, you are facing some issues in the production
24:46
So, you want to fix that issue as soon as possible. You can't fix the issue
24:54
on a cube mode. Like we are fixing the issue in the development
24:58
You have to make a build. You have to send to the
25:02
App Store and Play Store. They will first review it. Then they will make it public
25:08
So, it is like tedious task sometimes. Then this code came into the picture
25:16
What they will do? They will directly roll out the changes to
25:20
end-user device. So, you don't have to wait for small changes for the Play Store
25:26
and App Store to review your build. There are lots of apps
25:32
already doing. Like, take an example of LinkedIn. Sometimes, you will not update the
25:40
LinkedIn, but you will see some changes over there. So, LinkedIn is already
25:46
doing, I guess, Prime Video is already doing these changes. For React Native
25:52
App Center, the code whose name is App Center is there. So, Native developers are
25:58
using App Center. And for Flutter, there was not any single platform for the
26:04
code whose, but recently, I guess, one year back, one of the Google
26:10
team who was in the core team member of Flutter, they created this code whose platform
26:16
Okay. Currently, the Android version is in a stable mode, but the iOS is in alpha mode
26:22
So, they are really working very hard to make the iOS also in a
26:26
stable mode. And it is an open source project. So, if someone wants
26:30
to contribute in their project, they can go on GitHub and they can
26:34
see the issues and they can start contributing in the open source as well
26:40
That's good. I think this is a really handy tool one should learn, because
26:44
you are right. I mean, I use Instagram a lot throughout my day, and I see
26:50
sometimes they'll push some changes, and I don't have to go and update the
26:54
app. I can see the changes in the app. So, I think
26:58
having to learn this thing is really nice. And, if I just
27:04
missed it, where can people learn more of this stuff like this? I mean
27:08
this is a really nice thing, and I don't think people get to know
27:12
about this if they are learning it from YouTube or anywhere else, right? So
27:16
where do you share any of your tips or where do you learn
27:20
about Flutter and all that? So, most of the time, I am more
27:26
active on LinkedIn. So, if you are a Flutter developer, join any Flutter group, so
27:32
you will see lots of posted posts. Okay, whenever there are new things will come, they will post
27:38
You will see really nice posts. So, if you find anything which is interesting
27:42
just go and check them out, and you can follow the official social
27:48
handles of the Flutter. So, if there is any update and anything, you will get to know
27:54
And C-Sub Corner is one of them. So, there are a good community
27:58
of Flutter, so you can check out the C-Sub Corner as well
28:02
Yeah, MD, and that reminds me that we talk about starting a Flutter show
28:08
right? And I think it is time we start, but I need someone like you along
28:14
with me to co-host the Flutter show, because you are an expert, right
28:20
I reminded you for that show, I guess, in October. Yeah, you know
28:30
we did everything, I know this is getting off-topic, but you know, we had everything
28:34
for the show, logos and all. The show was supposed to be called Flutter Flight
28:40
I saw your post on LinkedIn, and I guess so many people recommended
28:44
you to host as well. Yeah, about 30-40 people, I think, you know what, MD
28:50
if I don't do it in the next two weeks, you complain to my boss
28:56
Because I think there's no real Flutter show going on in the
29:00
community, there may be one or two, but I don't know, but I think
29:04
we should start. The show is going on, actually, but those are not
29:10
from India, actually. Those are from the European countries. So, yeah, definitely we need
29:16
to do some show in India. Okay. And one thing I would like to add here is
29:22
Sourpad is not a free tool. Okay, so up to a certain limit
29:26
okay, it is free. If you are having a big user base
29:30
okay, then you have to pay the premium for that. So you can
29:34
go and check out the Sourpad platform and you can check out all these
29:38
premium and all these like, how much they are charging. Okay. Done. I'll definitely
29:46
do that. Thank you so much, MD. I really love this session. I believe everyone
29:50
watching in and who will watch later on when this video is on YouTube
29:54
they'll watch it at your face, their face, they will really love it. Any final thing you want
29:58
to plug in before we wrap up the show? For example? I mean, any
30:04
final words that you want to say before we, you know, finish
30:08
the show today? Okay. So, I would like to thank Cesar Pernel for
30:14
giving this opportunity to come and present and you, you are really great host. Okay, so
30:20
I am one, if you are an upcoming Flutter developers, okay, so yeah, as I said
30:26
like, try to follow Flutter's channel and all Flutter handles on all the social medias. Okay. And
30:34
try to brush up the basic things of Dart, okay, don't directly go and jump into the
30:40
like, getX or block and provider, first try to understand the basic
30:44
thing, then come into the restrict management, and yeah, Flutter is very good
30:50
SDK to build a really nice app. Yeah, so that's it. Nothing more
30:54
from my side. Thank you so much, Emily, you're always very kind and
30:58
thanks for all that you do for the community and for the C Sharp. We're really, really
31:02
blessed to have you. As I say, whenever we think of Flutter
31:08
MDSFrag is the name that strikes our head. So thank you so much, MD, and
31:12
thank you so much, everyone. That was it in the C Sharp on the MVP show. We'll see you
31:16
some other time. Until then, take care of yourself, and we'll see you soon. Ta-da
31:20
Bye-bye. Okay, bye, Simon. Bye. Have a good day
