showModalBottomSheet refresh patent view

[Igor Karelin]

I have a view which opening a ModalBottomSheet.

How can I refresh a parent controller state when the sheet is closing ?

From the modal sheet I'm adding/changing data in sqflite, and I need the way to refresh the data in parent view with the updated values.

How about passing a ValueNotifier from the parent to the ModalBottomSheet?

I’ve found a simple solution:

2-nd Page:

// sending "Bar" from 2nd
Navigator.pop(context, "Bar");

1-st Page:

// receiving "Bar" in 1st
String received = await Navigator.push(context, MaterialPageRoute(builder: (_) => Page2("Foo")));

So I receiving the String in the 1st controller and can execute the code regarding the ‘answer’ from the modal view.

Hi,

I think your controller calls every time that class loaded and it will unnecessarily waiting for something if you are coming from other places. Can’t you use popAndPushNamed in the second page,

Navigator.popAndPushNamed(comentext, '/page1');

Thanks

So this way I’ll dismiss a modal (second) controller and execute initState in the first controller (i. e. fully load parent controller) ?
