When generating code, errors occur due to disordered sequencing.

• injectable: 2.4.1
• injectable_generator: 2.6.1

Step 1 : In the code, I defined a structure like this.

@dev
@Singleton(as: EnvConfig)
class EnvConfigDev extends EnvConfig {
  EnvConfigDev() : super(Env.dev);

  @override
  String get apiUrl => Constants.saasApiDevHost;
}

@prod
@Singleton(as: EnvConfig)
class EnvConfigProd extends EnvConfig {
  EnvConfigProd() : super(Env.prod);

  @override
  String get apiUrl => Constants.saasApiHost;
}

@test
@Singleton(as: EnvConfig)
class EnvConfigTest extends EnvConfig {
  EnvConfigTest() : super(Env.test);

  @override
  String get apiUrl => Constants.saasApiHost;
}

Step 2 : use flutter packages pub run build_runner build --delete-conflicting-outputs to generate injectable.config.dart

_i1.GetIt init({
    String? environment,
    _i2.EnvironmentFilter? environmentFilter,
  }) {
    final gh = _i2.GetItHelper(
      this,
      environment,
      environmentFilter,
    );
    final registerModule = _$RegisterModule();
    .....
    /// line: 237
    gh.singleton<_i61.EnvConfig>(
      () => _i61.EnvConfigTest(),
      registerFor: {_test},
    );
    .....

    /// line: 274
    gh.singleton<_i61.EnvConfig>(
      () => _i61.EnvConfigDev(),
      registerFor: {_dev},
    );
   .....

    /// line: 288
    gh.singleton<_i75.ApiMethods>(
        () => _i75.ApiMethods.create(gh<_i61.EnvConfig>()));
   
    ....

    /// line: 342
    gh.singleton<_i61.EnvConfig>(
      () => _i61.EnvConfigProd(),
      registerFor: {_prod},
    );
     ....
    return this;
  }

Please take a look at the code. On line 288, the ApiMethods requires the EnvConfig parameter. However, if I use the prod environment parameter here, ApiMethods will not be generated. This is because the prod version of EnvConfig is defined only on line 342, which will cause an error here.

Previously, with version 2.3.2 of injectable and 2.4.1 of injectable_generator, everything worked normally.

The latest versions being used are:

• injectable: 2.4.1
• injectable_generator: 2.6.1

I have noticed a similar issue in 2.6.1.@Adam-Langley, works in <=2.6.0 with a workaround to have the same dependencies for all environments even if not needed.

Can confirm this issue: With version 2.6.1 of injectable_generator I get a wrong order of getIt registrations where in 2.6.0 it was still correct. Does it have something to do with use of environements? Cause in dev environment services everything was fine in my config, but maybe that was just pure luck...

We’re experiencing the same issue. For now, we are downgrading to 2.6.0 as a workaround.

Same issue on 2.6.2, is related with multiple enviroments
