I have async function in a Flutter widget that will perform these steps:

Future<void> someFunction(BuildContext context) async {
  // step 1:
  // call async function that will result in removing current widget from the tree.
  await foo();

  // at this point the context has no widget since the widget is removed from the tree

  // step 2:
  // need to show a dialog which requires a context with a widget.
  // since the context has no widget, I am unable to show the dialog
  // What can we do here??

  showDialog(context: context, .....);
}

Can someone suggest a solution. Thanks

Did you try it with a global context? https://stackoverflow.com/questions/66139776/get-the-global-context-in-flutter – Ozan Taskiran Feb 03 '23 at 13:51
Thanks for your help. That did work. I don't have to worry about passing context to dialogs from now on. Thanks – Aimn Blbol Feb 03 '23 at 16:23
Is there any disadvantage of using the global context that the article talks about? – Aimn Blbol Feb 04 '23 at 04:25
