ErrorHandler class abstract

Interface for GetxControllerPlus that simplifies error handling by delegating caught error-like Objects under most try-catch blocks into:

• Exposed View (Widgets, GetViews) codes
• Mutating existing state values under the GetxControllerPlus

Example:

Delegating handlers to a View scope (GetView example)

Widget build(BuildContext context) {

  controller.setErrorHandler<FormatException>(
    showDialog(
      context,
      builder: (context,) => AlertDialog(
        title: Text("Error",),
        message: Text("Failure to format something",),
      ),
    );
  );

  return MyWidget(
  ...
  );
}

Yet another example:

Mutate Observable states under GetXController itself

@override
void onInit() {
  setErrorHandler<IOException>(...);
  setErrorHandler<ArgumentError>(...);
}
