Unable to generate g.dart with retrofit flutter

I am migrating my flutter project to 3.3.0 and i am calling API with retrofit which was working fine, after upgrading all packages i delete .g.dart file and run the following command to rebuild the .g.dart file

flutter pub run build_runner build it thrown the following error.

    Error: No named parameter with the name 'autoCastResponse'.
      autoCastResponse: annotation?.peek('autoCastResponse')?.boolValue,

[SEVERE] Failed to precompile build script .dart_tool/build/entrypoint/build.dart.
This is likely caused by a misconfigured builder definition.
pub finished with exit code 78

I also try this command flutter packages pub run build_runner build --delete-conflicting-outputs But the result remains the same.

Here is how my abstract class looks like,

part 'rest_client.g.dart';
@RestApi(baseUrl: "https://myapi.com/")
abstract class RestClient {
   factory RestClient(Dio dio, {String baseUrl}) = _RestClient;

  @POST("/Flag")
  Future<LoginResponse> login(@Body() LoginRequest loginRequest)`;}`

These are my packages version:

retrofit: ^3.3.0

dev_dependencies:
flutter_test:
    sdk: flutter
  retrofit_generator: ^4.1.2
  build_runner: ^2.2.1
  json_serializable: ^6.4.1

  dependency_overrides:
    analyzer: '5.1.0'
Solution

  • According to this githubLink

    retrofit: 3.3.0 had bugs and the author forgot to publish the generator accordingly. So after resolving that bug using retrofit: ^3.3.1 and retrofit_generator: 4.2.0 is working fine
