• Running flutter pub outdated failed with the following output:

Note: collection is pinned to version 1.19.1 by flutter from the flutter SDK.
See https://dart.dev/go/sdk-version-pinning for details.

0/10 points: All of the package dependencies are supported in the latest version

• Could not run flutter pub outdated: flutter pub get failed:

OUT:
Resolving dependencies...
ERR:
Note: collection is pinned to version 1.19.1 by flutter from the flutter SDK.
See https://dart.dev/go/sdk-version-pinning for details.


Because every version of flutter from sdk depends on collection 1.19.1 and fp_util depends on collection 1.18.0, flutter from sdk is forbidden.
So, because fp_util depends on flutter from sdk, version solving failed.


You can try the following suggestion to make the pubspec resolve:
* Try upgrading your constraint on collection: flutter pub add collection:^1.19.1

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.
