Build Your Own Custom Code Generator in Flutter | Flutter Code Generation

It was an amazing tutorial and this may seem redundant to most but having this on your CV can give it a huge boost and make you stand out among thousands of CVs. As Rivaan mentioned, there aren't many resources where you can learn this so it's a huge contribution to the Flutter community as well.

My only issue with video is that there is an error in the model class even after running code gen which shouldn't be there and commenting a model class used in codegen is a bad practice. No one is going to remember why they did it after a few weeks. If some GDE or expert can point out the issue and the fix, it would be really helpful and Rivaan can pin it in the comment section.

I just discovered your channel, and I’m literally amused of the knowledge you covered in your videos, i have a question pls, do you have any idea about how the apps gen services (drag and drop) such as flutterflow works behind the scenes.

Hi, I did the same steps as you did but my code isn't generating .g files. However the build is successful.

example % flutter pub run build_runner build watch --delete-conflicting-outputs

Can you guide me i'm very new to this

Hi Rivan , thanks for the video , i have one question , how to use it in another app?

Alright, now I understand why everybody hates code generation in Dart.

Nice video thanks, although india english is a battle field hahaha, anyway you have a new subscriber

Amazing video rivaan

I was able to create simple generator that makes extension for class to create copyWith method without error

But unfortunately it turns out that this code doesn't work with latest plugin update i wasn't able to generate any code untill I've used your pubspec.lock file to lock to your versions 😅

I really appreciate your work if you got any new info please let us know on brief or new video for it will always be treat for eyes 🎉

Amazing video. How can I avoid using " part 'tartgetfile.g.dart' I am developing graphql types to dart class and providing help methods to initiate the classes with json(properly json from graphql request) pure graphql types

at one point your command line has "flutter pub run build_runner build watch " ... not sure but I think it should be "build" or "watch" ... not both?

this channel is amazing

You have a unique of teaching.
I appreciate your efforts and time for us.
I would request you to provide us a short video on bloc pattern in flutter.
That have main key points of bloc pattern.
Thanks 💌

How would I access the generic type of the annotation ex.: @MyAnnotation<Model> how do I get the Model classname. And how should I do imports in the generated code? Like how would I import the Model class?

great channel and great tut, well done.

Thanks bro.
How can i generate code from @Body for example ?

@POST('/login')
Future<BaseResponse<UserModel>> login({@Body() required BaseRequest<LoginRequestModel> loginRequestModel});

Super video bro.... Thanks a lot for info !!!🤟

create a series on awesome notification and local notification

At 25 minutes, you could have used `for (final entry in visitor.fields.entries)` and then referenced entry.key and entry.value without needing to reference the original structure. Much easier to avoid an off-by-1 problem as well..

Bro please make a home services app with backend..

Love from Bangladesh 🇧🇩
