    Because katana >=0.8.0-nullsafety.31 <1.0.4 depends on intl ^0.17.0 and every version of flutter_localizations from sdk depends on intl 0.20.2, katana >=0.8.0-nullsafety.31 <1.0.4 is incompat[...]

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.
