    Because katana_flutter >=0.14.0 <0.15.0+1 depends on katana ^0.14.0 which depends on intl ^0.17.0, katana_flutter >=0.14.0 <0.15.0+1 requires intl ^0.17.0.

    Because no versions of katana_annotation match >=0.15.0 <0.15.0+1 and katana_annotation >=0.15.0+1 depends on katana ^0.15.0, katana_annotation >=0.15.0 requires katana ^0.15.0.

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.
