[juliengit2]

same issue, and very annoying.

using channel stable + flare_flutter: ^1.5.4 (as indicated in https://github.com/2d-inc/Flare-Flutter/#flutter-channel) doesn't work.

I tried to change the type but it didn't work, any idea??

Also getting this, does anyone know the flare version that works?

It's a combination of the latest flutter stable (1.7.8+hotfix.3) and Flare 1.5.4. Both of those versions must be satisfied for the latest version of Flare and Flutter to work together (we strongly recommend you use these version).

It looks like you are using the old stable (v1.5.4-hotfix.2) which has a breaking change with Flutter 1.7.8+hotfix.3. Flare. Please upgrade to the latest Flutter stable.

Yea was just about to comment that updating flutter seemed to work (run "flutter upgrade") and then use the stable flare tag still. But if that isn't an option 1.5.0 also worked (although I wouldn't recommend hard versioning ever). Thanks for the reply @luigi-rosso

[luigi-rosso]

1.5.0 would work with the older Flutter stable 1.5.4-hotfix.2.

The cause of all of this is that Flutter changed the signature of a method Flare uses. This was a good change but it broke compatibility. If you use a version of Flutter with the old signature, you'll need to use a version of Flare that's <=1.5.3. If you're using the latest stable >=1.7.8+hotfix.3 then any flare_flutter >=1.5.4 will work.

In your case, flutter upgrade should get you up to the latest version. And then update your pubspec to flare_flutter: ^1.5.4 and call flutter pub get. That should get everything up to date!

[MustansirZia]

Well, shouldn't the latest version of Flutter (>=1.7.8+hotfix.3) be included in the environment section of the pubspec.yaml of this package? That shouldn't let us install the latest version of the package if we use an older Flutter version.

[luigi-rosso]

That's awesome, I didn't realize that was configurable. Thanks for the suggestion!
