CheckInternet Mixin

The CheckInternet mixin verifies device connectivity before an action executes. If there's no internet connection, the action aborts and displays a dialog with the message: "There is no Internet. Please, verify your connection."

Basic Usage

class LoadText extends AppAction with CheckInternet {

  Future<AppState?> reduce() async {
    var response = await http.get('https://api.example.com/text');
    return state.copy(text: response.body);
  }
}

The mixin works by overriding the before() method. If the device lacks connectivity, it throws a UserException which triggers the standard error dialog.
