[widgets/raw_menu_anchor.dart] Remove final class modifier on MenuController #174082
Description
Steps to reproduce
- Extend MenuController()
As noted in #167806 (comment):
Making the MenuController final just broke our code, we were extending the MenuController to add some animation functionality. Was this breaking change really intended?
Expected results
MenuController should be extensible.
Actual results
MenuController is not extensible because MenuController is final. An invalid_use_of_type_outside_library error is shown.
Code sample
Code sample
import 'package:flutter/material.dart';
class ExtendedMenuController extends MenuController {
ExtendedMenuController();
}
