如何使用Riverpod注入SharedPreferences依赖

dependencies:
  flutter_riverpod: ^1.0.0
  shared_preferences: ^2.0.6

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

final sharedPreferencesProvider = Provider<SharedPreferences>((ref) {
  return SharedPreferences.getInstance();
});

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

class MyWidget extends ConsumerWidget {
  @override
  Widget build(BuildContext context, ScopedReader watch) {
    final sharedPreferences = watch(sharedPreferencesProvider);

    // 读取数据
    final value = sharedPreferences.getString('key');

    // 写入数据
    sharedPreferences.setString('key', 'value');

    return Container();
  }
}
