To prevent the navigation bar from rebuilding during navigation in Flutter's widget structure, you can use the AutomaticKeepAliveClientMixin. This mixin tells Flutter to keep the state of the widget even when it's not visible on the screen.
Steps to implement this:
class MyPage extends StatefulWidget with AutomaticKeepAliveClientMixin {
@override
bool get wantKeepAlive => true;
@override
Widget build(BuildContext context) {
return Scaffold(
body: Builder(
builder: (BuildContext context) {
super.build(context);
return Container(
// Your content goes here
);
},
),
);
}
By wrapping the content in the Builder widget, we ensure that the build method is called only for the child widgets inside the Container and not for the entire Scaffold. Keeping the state of the widget alive prevents the navigation bar from being rebuilt during navigation.
