如何使用 auto_route package 在 flutter 应用程序中重新启动 TabPage 上的构建方法

Question

Hi a use auto_route package in flutter app. How to restart the build method on TabPage or not save the stack state when switching tabs. I should have an animation run in the build method on TabPage every time I switch a tab in the navigation bar. But the build method is not called when I click the buttons in the navigation bar

I guess you are the same user that commented on my article. I'll give the same answer here. this is not related to the autoroute package itself but it is the default behavior of a bottombar navigation. The objective being to always minimize the number of rebuilds necessary for your UI.

I didn't test it but you could try to make your tab a stateful widget (if it isn't already) and modify this behavior with the AutomaticKeepAliveClientMixin<YourWidget> :

class _YourWidgetState extends State<YourWidget> with AutomaticKeepAliveClientMixin<YourWidget>{

 // Here you build your Widget after calling the super method
@override Widget build(BuildContext context) { 
 super.build(context) 
 return Container(); 
} 

// the important part is returning false here
@override bool get wantKeepAlive => false; 

 }
