英文:
Flutter Injectable - Object/factory with type xxxxx is not registered inside GetIt
问题
I understand that you're having issues with the Injectable Flutter plugin and the error message you provided. It appears to be related to the registration of the FirebaseAuthRepository within the dependency injection configuration.
In your code, you have registered FirebaseAuthRepositoryImpl but not the abstract class FirebaseAuthRepository. To resolve this issue, you should register the abstract class as well. You mentioned that you tried injecting the abstract class, but it resulted in another error.
Here's the corrected code where you register the abstract class and the implementation:
import 'package:injectable/injectable.dart';
@prod
@lazySingleton
@Injectable(as: FirebaseAuthRepository)
class FirebaseAuthRepositoryImpl extends FirebaseAuthRepository {
// Implementation details here
}
Make sure that you have properly imported the required packages, especially the injectable package.
If you continue to face issues or have further questions, please provide more details about the specific error message you encountered when injecting the abstract class.

Im trying to use flutter plugin 'Injectable' but i got this error.
This error keeps coming even after having tried all the possible solutions provided in other questions
he following assertion was thrown building SignInPage(dirty, state: _SignInPageState#16126):
Object/factory with type FirebaseAuthRepository is not registered inside GetIt.
(Did you accidentally do GetIt sl=GetIt.instance(); instead of GetIt sl=GetIt.instance;
Did you forget to register it?)
'package:get_it/get_it_impl.dart':
Failed assertion: line 372 pos 7: 'instanceFactory != null'
the dependency injection config :
as you can see down below, i was confused with the error because the FirebaseAuthRepository have already registered inside the injection config
const String _prod = 'prod';
// ignore_for_file: unnecessary_lambdas
// ignore_for_file: lines_longer_than_80_chars
// initializes the registration of main-scope dependencies inside of GetIt
_i1.GetIt init(
_i1.GetIt getIt, {
String? environment,
_i2.EnvironmentFilter? environmentFilter,
}) {
final gh = _i2.GetItHelper(
getIt,
environment,
environmentFilter,
);
final registerModul = _$RegisterModul();
gh.lazySingleton<_i3.FirebaseAuth>(() => registerModul.firebaseAuth);
gh.lazySingleton<_i4.FirebaseAuthRepositoryImpl>(
() => _i4.FirebaseAuthRepositoryImpl(
remoteDataSource: gh<_i5.FirebaseAuthenticationRemoteDataSource>()),
registerFor: {_prod},
);
gh.lazySingleton<_i6.FirebaseAuthResetPassword>(
() => _i6.FirebaseAuthResetPassword(
repository: gh<_i7.FirebaseAuthRepository>()),
registerFor: {_prod},
);
gh.lazySingleton<_i8.FirebaseAuthSignIn>(
() => _i8.FirebaseAuthSignIn(repository: gh<_i7.FirebaseAuthRepository>()),
registerFor: {_prod},
);
gh.lazySingleton<_i9.FirebaseAuthSignOut>(
() => _i9.FirebaseAuthSignOut(repository: gh<_i7.FirebaseAuthRepository>()),
registerFor: {_prod},
);
gh.lazySingleton<_i10.FirebaseAuthSignUp>(
() => _i10.FirebaseAuthSignUp(repository: gh<_i7.FirebaseAuthRepository>()),
registerFor: {_prod},
);
gh.lazySingleton<_i5.FirebaseAuthenticationRemoteDataSourceImpl>(
() => _i5.FirebaseAuthenticationRemoteDataSourceImpl(
firebaseAuth: gh<_i3.FirebaseAuth>()),
registerFor: {_prod},
);

firebaseAuthResetPassword: gh<_i6.FirebaseAuthResetPassword>(),
));
return getIt;
}
class _$RegisterModul extends _i12.RegisterModul {}
the problem file :
this is the file mentioned in the debug console
abstract class FirebaseAuthRepository {
Future<Either<Failure, UserCredential>> authSignInEmailPassword(String email, String password);
Future<Either<Failure, UserCredential>> authSignUpEmailPassword(String email, String password);
Future<Either<Failure, void>> resetPassword(String email);
Future<Either<Failure, void>> authSignOut();
}
@prod
@lazySingleton
@Injectable(as: FirebaseAuthRepository)
class FirebaseAuthRepositoryImpl extends FirebaseAuthRepository {
final FirebaseAuthenticationRemoteDataSource remoteDataSource;
FirebaseAuthRepositoryImpl({
required this.remoteDataSource
});
@override
Future<Either<Failure, UserCredential>> authSignInEmailPassword(String email, String password) async {
try {
final result = await remoteDataSource.authSignInEmailPassword(email, password);
return Right(result);
} on SocketException {
return Left(ConnectionFailure('Failed to connect to network'));
} on FirebaseAuthException catch (e) {
if (kDebugMode) {
print('Failed with error code: ${e.code}');
return Left(FirebaseFailure('Failed with error code: ${e.code}'));
}
if (e.code == 'user-not-found') {
return Left(FirebaseFailure('No user found for that email'));
}
if (e.code == 'wrong-password') {
return Left(FirebaseFailure('Wrong password provided for that user'));
}
return Left(FirebaseFailure('Failed with error code: ${e.code}'));
}
}
@override
Future<Either<Failure, void>> authSignOut() async {
try {
final result = await remoteDataSource.authSignOut();
return Right(result);
} on SocketException {
return Left(ConnectionFailure('Failed to connect to network'));
} on FirebaseAuthException catch (e) {
if (kDebugMode) {
print('Failed with error code: ${e.code}');
}
return Left(FirebaseFailure('Failed with error code: ${e.code}'));
}
}
@override
Future<Either<Failure, UserCredential>> authSignUpEmailPassword(String email, String password) async {
try {
final result = await remoteDataSource.authSignInEmailPassword(email, password);
return Right(result);
} on SocketException {
return Left(ConnectionFailure('Failed to connect to network'));
} on FirebaseAuthException catch (e) {
if (kDebugMode) {
print('Failed with error code: ${e.code}');
return Left(FirebaseFailure('Failed with error code: ${e.code}'));
}
if (e.code == 'weak-password') {
return Left(FirebaseFailure('The password provided is too weak'));
}
if (e.code == 'email-already-in-use') {
return Left(FirebaseFailure('The account already exists for that email'));
}
return Left(FirebaseFailure('Failed with error code: ${e.code}'));
}
}
@override
Future<Either<Failure, void>> resetPassword(String email) async {
try {
final result = await remoteDataSource.resetPassword(email);
return Right(result);
} on SocketException {
return Left(ConnectionFailure('Failed to connect to network'));
} on FirebaseAuthException catch (e) {
if (kDebugMode) {
print('Failed with error code: ${e.code}');
}
return Left(FirebaseFailure('Failed with error code: ${e.code}'));
}
}
}
i tried injecting the abstract class but it won't work, instead i got another error
@injectable
abstract class FirebaseAuthRepository {
Future<Either<Failure, UserCredential>> authSignInEmailPassword(String email, String password);
Future<Either<Failure, UserCredential>> authSignUpEmailPassword(String email, String password);
Future<Either<Failure, void>> resetPassword(String email);
Future<Either<Failure, void>> authSignOut();
}

你应该使用 @injectable 或 lazySingleton 中的任何一个注解，不应该为单个实例使用两个注解 Injectable，两者表示相同的意思。
@prod
@LazySingleton(as: FirebaseAuthRepository)
或者
@prod
@Injectable(as: FirebaseAuthRepository)
你应该决定哪一个适合这个情况。
另外，FYI：你也可以在注解中使用 env 参数来决定环境。
@LazySingleton(as: FirebaseAuthRepository, env: ['prod'])
英文:
You should use either of one annotation @injectable or lazySingleton, You should not use two annotation for single instance Injectable, both represents the same.
@prod
@LazySingleton(as: FirebaseAuthRepository)
Or
@prod
@Injectable(as: FirebaseAuthRepository)
You should decide, which one is suitable for this.
In Additional, FYI: you can also use env parameter in annotation to decide the environment
@LazySingleton(as: FirebaseAuthRepository, env: ['prod'])
