pub package

async_redux_core

This is the core Dart-only package for the async_redux package.

In your Flutter app:

  • Do NOT include this core package directly.

    Instead, go to the async_redux package which already exports this core code, plus provides Flutter related code.

In your Dart server or Dart-only code:

  • For the moment, this Dart-only package simply contains the UserException class, and nothing more.

    • If you are creating code for a Dart server (backend) like Serverpod, or Celest, or developing some other Dart-only package that does not depend on Flutter, then you can use this package directly:

      import 'package:async_redux_core/async_redux_core.dart';

    Note: When using Serverpod or Celest, you can throw UserException in your backend code, and that exception will automatically be thrown in the frontend. As long as the Serverpod or Celest cloud function is called inside redux actions, Async Redux will display the exception message to the user in a dialog (or other UI element that you can customize). This can also be used with package i18n_extension_core to make sure the error message gets translated to the user's language. For example: UserException('The password you typed is invalid'.i18n); in the backend, will reach the frontend already translated as UserException('La contraseña que ingresaste no es válida') if the user device is in Spanish.

    Note: For this to work in Serverpod, after you import async_redux_core in the pubspec.yaml file of the server project, you must add the UserException class to your generator.yaml file, in its extraClasses section:

    type: server

client_package_path: ../my_client
server_test_tools_path: test/integration/test_tools

modules:
  serverpod_auth:
    nickname: auth
  
extraClasses:
  - package:async_redux_core/async_redux_core.dart:UserException
