Fixes PopupMenu does not update when PopupMenuTheme in Theme changes

Code sample

import 'package:flutter/material.dart';

void main() => runApp(const App());

class App extends StatelessWidget {
  const App({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      debugShowCheckedModeBanner: false,
      theme: ThemeData(
        colorScheme: const ColorScheme.light(),
        popupMenuTheme: PopupMenuThemeData(
          elevation: 10,
          color: Colors.red,
          shadowColor: Colors.black,
          surfaceTintColor: Colors.white,
          shape: RoundedRectangleBorder(
            borderRadius: BorderRadius.circular(10),
          ),
          menuPadding: EdgeInsets.all(10),
        ),
      ),
      darkTheme: ThemeData(
        colorScheme: const ColorScheme.dark(),
        popupMenuTheme: PopupMenuThemeData(
          elevation: 20,
          color: Colors.blue,
          shadowColor: Colors.white,
          surfaceTintColor: Colors.black,
          shape: RoundedRectangleBorder(
            borderRadius: BorderRadius.circular(20),
          ),
          menuPadding: EdgeInsets.all(20),
        ),
      ),
      home: const HomePage(),
    );
  }
}

class HomePage extends StatelessWidget {
  const HomePage({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Hello Flutter'),
        actions: [
          PopupMenuButton<int>(
            itemBuilder: (context) => <PopupMenuEntry<int>>[
              const PopupMenuItem<int>(value: 1, child: Text('Item 1')),
              const PopupMenuItem<int>(value: 2, child: Text('Item 2')),
              const PopupMenuItem<int>(value: 3, child: Text('Item 3')),
            ],
          )
        ],
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: const [Text('Nothing here')],
        ),
      ),
    );

Code Review

This pull request effectively addresses the issue where PopupMenu would not update its theme when the PopupMenuTheme in the Theme changes. The fix correctly removes the cached theme properties from PopupMenuButtonState and delegates the theme resolution to the showMenu implementation, which properly handles dynamic theme updates. The newly added regression test is comprehensive and accurately verifies that the menu's visual properties update correctly after a theme change. The changes are clean, well-targeted, and improve the framework's consistency.

packages/flutter/lib/src/material/popup_menu.dart

  void showButtonMenu() {
    // Ensure cached render objects are initialized
    _updateCachedObjects();
-    final PopupMenuThemeData popupMenuTheme = _popupMenuTheme;


If we remove the use of _popupMenuTheme here, do we still need it at all? Can we just remove this property?

Hi, thanks a lot for taking a look at this PR!
Unfortunately, no, as it is used in the _positionBuilder method to fix a possible crash. Some details can be found here: #171970.
