How we can change BottomNavigationBar page using Navigator push method without losing each page state?
extra details: that is useful on nested navigation, when we want to use Navigator.of method to access nearest Navigator on widget hierarchy. so we can change tabs from inside a tab content.
this situation is also a part of explained scenario on this question Flutter integrated stacked and tabbed navigations.
Use AutomaticKeepAliveClientMixin . After loading first time page state,there is no need to reload this(mens it's not losing it's old state)
Like this,
class ListWidget extends StatefulWidget { @override
_ListWidgetState createState() => _ListWidgetState();
}
class _ListWidgetState extends State<ListWidget> with AutomaticKeepAliveClientMixin<ListWidget>{ // ** here
@override
Widget build(BuildContext context) { return Container();
}
@override
bool get wantKeepAlive => true;
}
