我想知道，如果有人知道一种方法，以删除显示在appBar在颤振应用程序，当你使用Navigator。pushNamed转到另一个页面。我不希望它出现在这个结果页面上的原因是它来自导航，我希望用户使用注销按钮，这样会话就可以重新开始。

SliverAppBar ( automaticallyImplyLeading:假的,}

只是让它透明，没有行动，而现在
AppBar(
leading: IconButton(
icon: Icon(
Icons.arrow_back,
color: Colors.white.withOpacity(0),
),
onPressed: () {},
),
使用这个条子AppBar
SliverAppBar (
automaticallyImplyLeading: false,
elevation: 0,
brightness: Brightness.light,
backgroundColor: Colors.white,
pinned: true,
),
使用这个正常的Appbar
appBar: AppBar(
title: Text
("You decide on the appbar name"
style: TextStyle(color: Colors.black,),
elevation: 0,
brightness: Brightness.light,
backgroundColor: Colors.white,
automaticallyImplyLeading: false,
),
appBar: new AppBar(title: new Text("SmartDocs SPAY"),backgroundColor: Colors.blueAccent, automaticallyImplyLeading:false,
leading: new Container(),
),
工作正常
我认为解决办法如下
你实际上可以:
Don't want to display that ugly back button ( :] ), and thus go for : AppBar(...,automaticallyImplyLeading: false,...); Don't want the user to go back - replacing current view - and thus go for: Navigator.pushReplacementNamed(## your routename here ##); Don't want the user to go back - replacing a certain view back in the stack - and thus use: Navigator.pushNamedAndRemoveUntil(## your routename here ##, f(Route<dynamic>)→bool); where f is a function returning truewhen meeting the last view you want to keep in the stack (right before the new one); Don't want the user to go back - EVER - emptying completely the navigator stack with: Navigator.pushNamedAndRemoveUntil(context, ## your routename here ##, (_) => false);
只需在AppBar()中使用automcallyimplyleading即可
appBar: AppBaar(
automaticallyImplyLeading: false,
)
