I wanted to render multiple Rive animations on a page, but the page crashed.

[Conn-Ho]

The watchdog timed out, and the software crashed directly. The main thread (Thread 0) got stuck on the rive::gpu::RenderContext::flush() operation.
Could you please suggest any optimization methods?

[Conn-Ho]

help me！ Please！

[HayesGordon]

Can you share a reproduction?

• Which version are you using?
• Which platform is crashing?

We need to add extra warnings not to use Factory.rive for too many graphics on the same page, as it will have a big performance cost. But it shouldn't crash.

Can you share a reproduction?

• Which version are you using?
• Which platform is crashing?

We need to add extra warnings not to use Factory.rive for too many graphics on the same page, as it will have a big performance cost. But it shouldn't crash.

Can I offer you this as a reference? Thank you very much!

This should be fixed in 0.0.5! If updating doesn't resolve it, can you please share a sample project that reproduces the crash so we can investigate?

Additional note, we just release version 0.14.0-dev.2 of the rive package. Which adds rive_native to this package. This has a more fleshed out API designed for runtime usage.

You can read more here:

• Migration Guide
• Rive Native for Flutter
• Rive Flutter Docs

If you're having issues updating to the latest, please open a new issue with reproducible steps.

OK, I will update the package to use version 0.0.5 again for testing. Besides that, I will also try using the rive package version 0.14.0-dev.2. (By the way, we migrated over when the rive native was updated to 0.0.3 because at that time the rive package did not support data binding. ) Now the newly updated 0.14.0-dev.2 might help us a lot. I will give you feedback as soon as possible. Please don't close the issue. If the problem still cannot be solved, I will provide you with the rev file and the code we are developing.

[HayesGordon]

@Conn-Ho, I'll go ahead and close this. But please reopen if you're still experiencing issues. I believe this should be resolved in 0.0.5, but we also just did a release, v0.0.6, which addressed another iOS/macOS issue. The code around these mutex locks has changed and should no longer be an issue.

@HayesGordon Hello, the issue you provided regarding improving the performance of Rive was effective. Thank you very much.
Now there are some new problems. I want to control the progress of a certain animation timeline in Rive using Flutter. Do you have any related APIs? I haven't found them in the code yet.
