onInit method

@override Future<void> onInit()

Called immediately after the widget is allocated in memory. You might use this to initialize something for the controller.

Implementation

@override
Future<void> onInit() {
  // For each field
  for (final field in fields) {
    // Set text controllers
    _textControllers[field] = TextEditingController(
      // Set the default values if they exist
      text: defaultValues[field],
    );

    // Set focus Nodes
    _focusNodes[field] = FocusNode();
  }
  return super.onInit();
}
