Flutter 小结

1. If you're running pod install manually, make sure flutter pub get is executed first"

cd 到工程的iOS目录执行以下命令：flutter packages get

2. 空安全运行：

flutter run --no-sound-null-safety

3.创建Flutter项目时指定语言：

flutter create -i objc -a java

4.Tabbar

class MyApp extends StatelessWidget {
  MyApp({Key? key}) : super(key: key);
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false, // debug 图标
      home: Tabs(),
      theme: ThemeData(primarySwatch: Colors.lightBlue),
    );
  }
}

class _TabsState extends State<Tabs> {
  int _current = 0;
  List pageList = [Home(), Product(), Discover(), MinePage()];
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: this.pageList[this._current],
      bottomNavigationBar: BottomNavigationBar(
        iconSize: 40,
        currentIndex: this._current,
        type: BottomNavigationBarType.fixed,
        onTap: (value) {
          setState(() {
            this._current = value;
          });
        },
        items: [
          BottomNavigationBarItem(icon: Icon(Icons.home), label: '首页'),
          BottomNavigationBarItem(icon: Icon(Icons.catching_pokemon), label: '项目'),
          BottomNavigationBarItem(icon: Icon(Icons.badge_sharp), label: '发现'),
          BottomNavigationBarItem(icon: Icon(Icons.settings), label: '设置'),
        ],
      ),
    );
  }
}

5 Navigation导航

    return Scaffold(
      appBar: AppBar(
        title: Text('标题'),
      ),
      body: Container(),
    );
