Flutter學習，第一個自己想實現的方法，界面跳轉的實現

flutter學習，也看了幾天了，想做下筆記爲以後使用做好筆記， 今天做了一個界面跳轉的筆記

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
        accentColor: Colors.cyan[600],
      ),
      home: MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key, this.title}) : super(key: key);
  final String title;
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
        actions: <Widget>[
          new IconButton(icon: new Icon(Icons.list), onPressed: _pushSaved)
        ],
      ),
    );
  }
  void _pushSaved(){
    Navigator.of(context).push(
      new MaterialPageRoute(builder: (context){
        return new Scaffold(
          appBar: new AppBar(
            title: new Text('Save Suggestions'),
          ),
        );
      }),
    );
  }
}
