在我使用 flutter_riverpod stateprovider 重新保存代码之前，UI 主题状态不会更新

我需要改变主题使用状态提供者的Flutter 河舱，我不明白我做错了什么

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  runApp(const ProviderScope(child: MyApp()));
}

class MyApp extends ConsumerWidget {
  const MyApp({super.key});
  @override
  Widget build(BuildContext context, WidgetRef ref) {
    final isDarkTheme = ref.watch(isDarkThemeProvider.notifier).state;

    return GestureDetector(
      onTap: () {
        FocusScope.of(context).unfocus();
      },
      child: ScreenUtilInit(
        designSize: const Size(360, 690),
        minTextAdapt: true,
        splitScreenMode: true,
        builder: (context, child) {
          return MaterialApp(
              builder: FToastBuilder(),
              debugShowCheckedModeBanner: false,
              title: 'code',
              theme: isDarkTheme ? Themes().darkTheme : Themes().lightTheme,
              onGenerateRoute: onAppGenerateRoute(),
              routes: appRoutes(),
              initialRoute: SplashPage.route);
        },
      ),
    );
  }
}

这是我的主题类和主题状态提供程序

import 'package:flutter/material.dart';
import 'package:flutter_riverpod/flutter_riverpod.dart';
import 'package:tr_qr_code/utils/colors.dart';

class Themes {
  final ThemeData lightTheme = ThemeData(
    scaffoldBackgroundColor: colorWhite,
    splashColor: Colors.transparent,
    highlightColor: Colors.transparent,
    appBarTheme: const AppBarTheme(color: colorWhite),
    fontFamily: 'OpenSans',
    useMaterial3: true,
  );

  final ThemeData darkTheme = ThemeData(
    scaffoldBackgroundColor: colorBlack,
    splashColor: Colors.transparent,
    highlightColor: Colors.transparent,
    appBarTheme: const AppBarTheme(color: colorBlack),
    fontFamily: 'OpenSans',
    useMaterial3: true,
  );
}

final isDarkThemeProvider = StateProvider<bool>((ref) => false);

在ONTAP内的拨动switch 上，使用以下代码来更新状态

onTap: () {
    
              ref.read(isDarkThemeProvider.notifier).update(
                  (state) => !ref.read(isDarkThemeProvider.notifier).state);
            },

我try 了Flutter 翼清洁，Flutter 翼wine 吧升级等.
