flutter使用shared_preferences本地存储基础信息

请求类：

import 'package:shared_preferences/shared_preferences.dart';

class Storage {
  static Future<void> setString(key, value) async {
    SharedPreferences sp = await SharedPreferences.getInstance();
    sp.setString(key, value);
  }

  static Future<String?> getString(key) async {
    SharedPreferences sp = await SharedPreferences.getInstance();
    return sp.getString(key);
  }

  static Future<void> remove(key) async {
    SharedPreferences sp = await SharedPreferences.getInstance();
    sp.remove(key);
  }

  static Future<void> clear() async {
    SharedPreferences sp = await SharedPreferences.getInstance();
    sp.clear();
  }
}

import 'storage.dart';

Storage.setString("password", _password);

Storage.setString("username", _username);
