downgrade analysis failed failed with 17 errors:

• URI_DOES_NOT_EXIST - lib/utils.dart:1:8 - Target of URI doesn't exist: 'dart:ui'.
• NON_TYPE_AS_TYPE_ARGUMENT - lib/utils.dart:13:8 - The name 'Image' isn't a type, so it can't be used as a type argument.
• UNDEFINED_FUNCTION - lib/utils.dart:14:23 - The function 'instantiateImageCodec' isn't defined.

Run flutter pub downgrade and then flutter analyze to reproduce the above problem.

You may run dart pub upgrade --tighten to update your dependency constraints, see dart.dev/go/downgrade-testing for details.
