Implementation

void dispose() {
  // Ensure the handler is created all over again
  _this = null;
  // Reset allowances
  _allowNewErrorHandlers = true;
  _setErrorHandler = false;
  // Ensure error routines are reset, but then set to null
  deactivate();
  // App's FlutterError.onError
  _flutteryExceptionHandler = null;
  // the App's ErrorWidget.builder;
  _flutteryErrorWidgetBuilder = null;
  // Keep it if testing however
  if (App.inWidgetsFlutterBinding) {
    _oldBuilder = null;
  }
  _oldOnError = null;
}
