UnsupportedError: A new runtime is likely necessary to play this file.

[yinleiCoder]

Oh! please help me. I upgraded to the new version(v0.7.0), then can't load my file. It throws such an error: Unsupported property key , A new runtime is likely necessary to play this file.

void _loadRiveFile() async {
    // Load the animation file from the bundle, note that you could also
    // download this. The RiveFile just expects a list of bytes.
    rootBundle.load(riveFileName).then(
          (data) async {
        // Load the RiveFile from the binary data.
        final file = RiveFile.import(data);
        // The artboard is the root of the animation and gets drawn in the
        // Rive widget.
        final artboard = file.mainArtboard;
        // Add a controller to play back a known animation on the main/default
        // artboard.We store a reference to it so we can toggle playback.
        artboard.addController(_riveController = SimpleAnimation('drive'));
        setState(() => _artboard = artboard);
      },
    ).catchError((e) => print(e));
  }

Unsupported operation: Unsupported property key 1351. A new runtime is likely necessary to play this file.

i clone your example project and run ,It's the same mistake

It is probably related with:

New binary format 7.0 with improved flexibility which is not compatible with 6.0 files. The Rive editor will be able to export both format 6.0 and 7.0, but please note that 6.0 is now deprecated and all new improvements and bug fixes to the format will be done on 7.0.

it's right. I solved the problem by changing the RIV file.Thank you!

I don't know if any of you guys are devs, but it's pretty ridiculous that most of the few Rive examples don't actually work/aren't supported with the new version of rive. Personally I'm using Rive for a production project and am able to work around that, but it's pretty unfair to any of the other devs out there trying to learn how to use this package.

Sorry for all the confusion around all of this. We sometimes add features that require modifying the runtime format. The format is getting more resilient to breaking changes so we hope to need to do this even more rarely in the future.

Two examples are provided in this repo under the example folder. If there's something specific you're looking for, please let us know. We also have a pretty strong community on Discord.

All old v6 files will still work on 0.6.x packages if you cannot get a newer export. The editor also offers exporting both v6 and v7 files, so whichever package version you are on you should still able to export content for it.
