flutter 简单存token到本地

用到shared_preferences

dependencies:
            shared_preferences: ^2.2.0

 

import 'package:shared_preferences/shared_preferences.dart';

// 保存token
Future<void> setToken(String token) async {
  SharedPreferences prefs = await SharedPreferences.getInstance();
  await prefs.setString('token', token);
}

Future<String?> getToken() async {
  SharedPreferences prefs = await SharedPreferences.getInstance();
  String? token = prefs.getString('token');
  return token;
}
