To reproduce run dart pub outdated --no-dev-dependencies --up-to-date --no-dependency-overrides.

The constraint `>=0.9.7 <0.11.0` on camera does not support the stable version `0.11.0`.

Try running dart pub upgrade --major-versions camera to update the constraint.

Passed check 10/10 points: Package supports latest stable Dart and Flutter SDKs

Failed check 0/20 points: Compatible with dependency constraint lower bounds

downgrade analysis failed failed with 3 errors:

  • UNDEFINED_ENUM_CONSTANT - lib/src/ui/reader_widget.dart:534:29 - There's no constant named 'nv21' in 'ImageFormatGroup'.
  • UNDEFINED_METHOD - lib/src/utils/image_converter.dart:30:16 - The method 'getBytes' isn't defined for the type 'Image'.
  • UNDEFINED_PREFIXED_NAME - lib/src/utils/image_converter.dart:30:39 - The name 'ChannelOrder' is being referenced through the prefix 'imglib', but it isn't defined in any of the libraries imported using that prefix.

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.
