Getting parent object info from Flutter app












0















I’m creating mobile application with Flutter.
This application has two forms (screens).
For example:



class MainScreen  extends StatelessWidget {

@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AdvertAppBar(context),
body: Container(…),

),
);
}
}


And



class ListScreen  extends StatelessWidget {
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AdvertAppBar(context),
body: Container(…),

),
);
}
}


As you could see I’m using shared appBar which instantiates from external class (AdvertAppBar).
Is there any way to know from appBar class what the class of parent object (MainScreen or ListScreen)?

  • You may be able to do this using the inheritedWidgetOfExactType method but it might be better if you simply pass data into your AdvertAppBar class. What exactly are you trying to acheive?

  • did you context.widget.runtimeType

  • @JordanDavies From MainScreen I want to call ListScreen (Navigator.push(context, MaterialPageRoute(builder: (context) => ListScreen()),); ), but from ListScreen I want only refresh content of the ListScreen. Yeah, I can pass some parameter (say current form name) into AdvertAppBar constructor, but I think is there some more appropriate approach?

  • From what I understood from your question is that you are trying to only load the content of your ListView widget without reloading your appBar am I right ?
