Flutter -重启应用程序时清除应用程序数据

import 'package:flutter/material.dart';
import 'package:shared_preferences/shared_preferences.dart';
import 'package:flutter_restart/flutter_restart.dart'; // 需要添加flutter_restart包

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: Text('Clear Data Example')),
        body: ClearDataButton(),
      ),
    );
  }
}

class ClearDataButton extends StatefulWidget {
  @override
  _ClearDataButtonState createState() => _ClearDataButtonState();
}

class _ClearDataButtonState extends State<ClearDataButton> {
  Future<void> _clearDataAndRestart() async {
    SharedPreferences prefs = await SharedPreferences.getInstance();
    await prefs.clear(); // 清除所有SharedPreferences数据
    FlutterRestart.restartApp(); // 重启应用
  }

  @override
  Widget build(BuildContext context) {
    return Center(
      child: ElevatedButton(
        onPressed: _clearDataAndRestart,
        child: Text('Clear Data and Restart'),
      ),
    );
  }
}
