Connection problem to backend

[aksebzeci]

Hello,

I run backend on localhost. When I run app on I get authentication errors. Also, I get internet connection error in registration screen.

Here is my .env file:
API_BASE_URL = 'http://localhost:8000/app/'

Also, I tried these links in API_BASE_URL too. But It didn't work.
'http://localhost:8000/api/'
'http://localhost:8000/'

When the app load I get errors on console log:
flutter: AuthBloc AuthAppStartedEvent()
flutter: AuthBloc Transition { currentState: AuthStateInitial(), event: AuthAppStartedEvent(), nextState: AuthStateLoading() }
flutter: AuthBloc Change { currentState: AuthStateInitial(), nextState: AuthStateLoading() }
flutter: AuthBloc type 'String' is not a subtype of type 'int' of 'index'
flutter: AuthBloc _AuthStatusChangedEvent(Instance of 'AuthUnknown')
flutter: AuthBloc Transition { currentState: AuthStateLoading(), event: _AuthStatusChangedEvent(Instance of 'AuthUnknown'), nextState: AuthStateUnknown([]) }
flutter: AuthBloc Change { currentState: AuthStateLoading(), nextState: AuthStateUnknown([]) }

The error in registration screen:

Are you running the app in a browser?

I have fixed the type casting error on the register page

@override
  Future<void> register(User user, String password) async {
    FormData formData = FormData();

    if (user.profileImageUrl != null) {
      formData.files.add(MapEntry(
        "profile_image",
        await MultipartFile.fromFile(user.profileImageUrl!, filename: user.profileImageUrl!.split('/').last),
      ));
    }

    // i added this line
    Map<String, dynamic> newUser = user.toJson().map((key, value) => MapEntry(key, value ?? 'null'));

    formData.fields.addAll(newUser.cast<String, String>().entries);
    formData.fields.add(MapEntry('password', password));

    await _dio.post(
      '/users',
      data: formData,
    );
  }

I've tried using localhost:8080 (using php spark serve) but it doesn't work.
My suggestion is to use local hosting using a webserver like apache or XAMPP.

Hello again,

I setup local and remote backend servers. But I couldn't get it run. Can you use this url and debug the problem?

API_BASE_URL = 'https://mezatla-backend-aaebd516df80.herokuapp.com/'

Also, I get this error in login screen:

LoginBloc type 'String' is not a subtype of type 'int' of 'index'
