Error running Teddy sample: The argument type 'Uint16List' can't be assigned to the parameter type 'Int32List'

Hi,

I have this error after run the teddy example:

`Compiler message:

Hi,

There’s a breaking change between flutter stable and dev/master. If you wish to use flutter stable, please use the corresponding Flare-Flutter stable branch. Our master and dev branches are kept up to date with flutter master and dev.

I suspect you checked out the example from our master branch. If so, either switch to flutter master/dev or checkout Flare-Flutter branch stable.

For those having this issue, you can change your pubspec.yaml to the following:

flare_flutter:
      git:
        url: https://github.com/2d-inc/Flare-Flutter.git
        path: flare_flutter
        ref: dev

This currently also happens in the betabranch

Is it master that is broken? Seeing this on a custom app build with version 1.5.1 which is the version specified on pub.

Unfortunately Flutter has changed their API between their stable and master/dev channels, but we've updated our runtime to comply with those changes.

Our README has a compatibility list, so everyone can keep using their Flutter channel, they just need to use the correct branch - that is:
Flutter Stable: Flare-Flutter "stable" branch
Flutter Master: Flare-Flutter "master" branch
Flutter Dev: Flare-Flutter "dev" branch

Use the flutter channel command in a terminal to view the currently active flutter channel.

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??

@juliengit2 you will need flutter 1.7 as the stable

[juliengit2]

@hyperionstudios thank you! I was using 1.5.4, am upgrading to 1.7 and hope it'll work

Flutter stable was upgraded a few days ago, we upgraded our stable to match. If you’re seeing this error, you likely haven’t upgraded yet.

flutter channel stable
flutter upgrade

[juliengit2]

yes it worked after upgrading
