This a a flare issue, for the moment it is safe to ignore is more like a warning. When they fixed i will update de version of dependency.

dependency_overrides:
flare_flutter :
git:
url: https://github.com/mdpe-ir/Flare-Flutter
path: flare_flutter

Flare is not maintained anymore. You have to migrate to Rive 2 instead.

There is no easy migration from flare to Rive. Rive 2 is not fully backguard compatible, i do not have time to recreate al animation in rive2. So by now i will be using dependency override for the flare package pointing to a PR with the Fix.

[Ruslanbek0809]

If you still get issue using dependency override put it like this:

dependency_overrides:
  flare_flutter :
    git:
      url: https://github.com/mdpe-ir/Flare-Flutter
      path: flare_flutter
      ref: stable

It should work without a problem.

[marcos930807]

The version 3.0 is out with new Rive runtime for animation a some other changes. Now the problem is gone.
