通常和CupertinoPageScaffold一起使用 2 构造函数 CupertinoNavigationBar({ Key key, this.leading, this.automaticallyImplyLeading...defaultHeroTag, }) 3 常用属性 3.1 leading:导航栏左侧组件,leading优先级高于previousPageTitle leading: Icon(Icons.arrow_back), 3.2 automaticallyImplyLeading...:是否显示左边组件 automaticallyImplyLeading : true, 3.3 automaticallyImplyMiddle:是否显示中间组件 automaticallyImplyMiddle
* AppBar({ Key key, this.leading,//在标题前面显示的一个控件,在首页通常显示应用的 logo;在其他界面通常显示为返回按钮 this.automaticallyImplyLeading...onPressed: () { print('返回'); }, ), //自定义返回图标样式 automaticallyImplyLeading
Material | automaticallyImplyLeading 取消 AppBar 前面的返回图标有多种方式; Scaffold 外层嵌套 Material; @override Widget...Scaffold( appBar: AppBar(title: Text('Dialog Page')), body: _bodyWid())); } AppBar 中的 automaticallyImplyLeading...Widget build(BuildContext context) { return Scaffold( appBar: AppBar(title: Text('Dialog Page'), automaticallyImplyLeading
automaticallyImplyLeading automaticallyImplyLeading是用在AppBar中的属性,表示是否需要实现leading widget。
和尚这次尝试用 SliverAppBar 来处理; SliverAppBar 源码分析 const SliverAppBar({ Key key, this.leading, this.automaticallyImplyLeading...this.floating = false, this.pinned = false, this.snap = false, }) leading:顶部左侧 Widget 常见的是返回按钮; automaticallyImplyLeading...title: Text('Sliver Title Sliver Title Sliver Title'), leading: Icon(Icons.reply), automaticallyImplyLeading
2 构造函数 AppBar({ Key key, this.leading, this.automaticallyImplyLeading = true, this.title
context) { return Scaffold( appBar: AppBar( centerTitle: true, // 标题内容居中 automaticallyImplyLeading...BuildContext context) { return Scaffold( appBar: AppBar( centerTitle: true, automaticallyImplyLeading...BuildContext context) { return Scaffold( appBar: AppBar( centerTitle: true, automaticallyImplyLeading...BuildContext context) { return Scaffold( appBar: AppBar( centerTitle: true, // automaticallyImplyLeading
return Scaffold( appBar: AppBar( automaticallyImplyLeading: false, title: Text("Custom...override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( automaticallyImplyLeading
AppBar( automaticallyImplyLeading: false, // simple as that!...key, this.leading,//左侧显示的图标 通常首页显示的为应用logo 在其他页面为返回按钮 this.automaticallyImplyLeading = true,/
AppBar AppBar({ Key key, this.leading, this.automaticallyImplyLeading = true, this.title, this.actions...automaticallyImplyLeading 官方的解释为 Controls whether we should try to imply the leading widget if null...icon: Icon( Icons.nature ), ), automaticallyImplyLeading
AppBar 的使用细节 AppBar 在构造时可以传入 automaticallyImplyLeading 属性,用于控制是否在 leading 为 null 时,根据场景自动添加某些图标:比如 Scafflod...如果不想启用个功能,将 automaticallyImplyLeading 置为 false 即可。
