如何在复选框中保存复选框状态？

Question

我有100个要做的复选框，我想保存其状态。因此，重新启动后该值应该存在。 有没有简单的方法。

下面是我目前正在处理的事情。

import 'package:flutter/material.dart';
void main(){
  runApp(new MaterialApp(
    home: new MyApp(),
  ));
}

class MyApp extends StatefulWidget {
  @override
  _State createState() => new _State();
}
//State is information of the application that can change over time or when some actions are taken.
class _State extends State<MyApp>{

  bool _value1 = false;
  bool _value2 = false;

  //we omitted the brackets '{}' and are using fat arrow '=>' instead, this is dart syntax
  void _value1Changed(bool value) => setState(() => _value1 = value);
  void _value2Changed(bool value) => setState(() => _value2 = value);

@override
  Widget build(BuildContext context) {
    return new Scaffold(
      appBar: new AppBar(
        title: new Text('Name here'),
      ),
      //hit Ctrl+space in intellij to know what are the options you can use in flutter widgets
      body: new Container(
        padding: new EdgeInsets.all(32.0),
        child: new Center(
          child: new Column(
            children: <Widget>[
              new CheckboxListTile(
                  value: _value2,
                  onChanged: _value2Changed,
                  title: new Text('Check box 1'),
                  controlAffinity: ListTileControlAffinity.leading,
                  subtitle: new Text('100th'),
                  secondary: new Icon(Icons.archive),
                  activeColor: Colors.red,
              ),

              new CheckboxListTile(
                  value: _value2,
                  onChanged: _value2Changed,
                  title: new Text('Check box 2'),
                  controlAffinity: ListTileControlAffinity.leading,
                  subtitle: new Text('99th'),
                  secondary: new Icon(Icons.archive),
                  activeColor: Colors.red,
              ),
            ],
          ),
        ),
      ),
    );
  }
}
