Flutter :如何在多页面中使用带有SharedPreference和List<String>变量的Riverpod？

dependencies:
  riverpod: ^0.15.0
  shared_preferences: ^2.0.6

import 'package:flutter_riverpod/flutter_riverpod.dart';
import 'package:shared_preferences/shared_preferences.dart';

final sharedPreferencesProvider = Provider<SharedPreferences>((ref) {
  throw UnimplementedError();
});

final myDataListProvider = Provider<List<String>>((ref) {
  final sharedPreferences = ref.watch(sharedPreferencesProvider);
  final dataList = sharedPreferences.getStringList('dataList');
  return dataList ?? [];
});

final saveDataListProvider = Provider<VoidCallback>((ref) {
  final sharedPreferences = ref.watch(sharedPreferencesProvider);
  return () async {
    // 从Riverpod的Provider中获取数据列表
    final dataList = ref.read(myDataListProvider).state;
    await sharedPreferences.setStringList('dataList', dataList);
  };
});

Consumer(
  builder: (context, watch, _) {
    final dataList = watch(myDataListProvider);
    return ListView.builder(
      itemCount: dataList.length,
      itemBuilder: (context, index) {
        return ListTile(
          title: Text(dataList[index]),
          onTap: () {
            // 点击时删除数据列表项
            final updatedList = dataList.toList()..removeAt(index);
            context.read(myDataListProvider).state = updatedList;
            context.read(saveDataListProvider)();
          },
        );
      },
    );
  },
)
