A flutter clean architecture series, the way we build clean apps.

flutter-clean-architecture's Issues

Imports of core package into domain package.

In the domain package you have some imports from the core package ( in usecases and repositories folders ). The main advantage of the hexagonal architecture is explicitly to avoid such imports.
The problem here is that the ports aren't part of the domain but of the application layer ( core package ).

Rename "usecaes" folder name

DioError

DioError does not work with the new version of Dio:

1. "request" renamed to requestOptions
2. DioErrorType.RESPONSE -> DioErrorType.response

It is no good idea to use DioError in DataState I think. HTTP 403/404/500 etc.. is not a Dio error in fact.

BlocWithState Deprecated

Some new useful packages

I am reading your medium articles and checking your code so I thought that you might be able to make the code cleaner by using freezed instead of the regular class generated with the VSCode extensions.
Which will need a few tweaks in order to implement it cause you are already using the build runner

mapEventToState removed in favor of on<Event>

[Help] How to use Token authorization in header instead of API key

Thanks for the great articles and example code!

My system uses Token Authentication in which an user token is attend to the Http Request header. How would you recommend migrating the example to place this in the header rather than using the APIKey?

Thank you,
