Notification Error

[gulmensedat]

════════ Exception caught by scheduler library ═════════════════════════════════════════════════════
The following assertion was thrown during a scheduler callback:
Tried to listen to a value exposed with provider, from outside of the widget tree.

This is likely caused by an event handler (like a button's onPressed) that called
Provider.of without passing listen: false.

To fix, write:
Provider.of(context, listen: false);

It is unsupported because may pointlessly rebuild the widget associated to the
event handler, when the widget tree doesn't care about the value.

The context used was: HomePage(dependencies: [_DefaultInheritedProviderScope], state: _HomePageState#074c3)
'package:provider/src/provider.dart':
Failed assertion: line 193 pos 7: 'context.owner.debugBuilding || listen == false || _debugIsInInheritedProviderUpdate'

Either the assertion indicates an error in the framework itself, or we should provide substantially more information in this error message to help you determine and fix the underlying cause.
In either case, please report this assertion by filing a bug on GitHub:
https://github.com/flutter/flutter/issues/new?template=BUG.md

When the exception was thrown, this was the stack:

I got this error after reinstalling it. I think the reason I got this error is because I did not set the notification correctly. I couldn't find how to produce Key.
