Awesome Notifications V0.7.3 on flutter fails to build-CodePudding

I added the awesome notifications package to my flutter project and initialized it in the main.dart file but when I try to build the app I get this error: `

You need to update your flutter version:

flutter upgrade

Or downgrade awesome_notifications to older version.

Issue: DecoderBufferCallback not found / Uint8List not found

Fix: You need to update your Flutter version running flutter upgrade. These methods was added/deprecated sice version 2.12.
