Camera: Incompatible version 0.9.4+12 #98660
Description
It seems that the version 0.9.4+12 of the camera package is not compatible with older ones.
I used to have camera: ^0.9.4+5 in my pubspec.yaml and during building, I get the following error:
../programs/flutter/.pub-cache/hosted/pub.dartlang.org/camera-0.9.4+12/lib/src/camera_controller.dart:813:15: Error: The argument type 'Future<void>?' can't be assigned to the parameter type 'Future<void>' because 'Future<void>?' is nullable and 'Future<void>' isn't.
- 'Future' is from 'dart:async'.
unawaited(_deviceOrientationSubscription?.cancel());
However, when I change the version of the package to camera: 0.9.4+11, there is no error and the build is successful.
