Flutter test fail on Ubuntu 22.04

Submission checklist

• I have confirmed the issue is present in the latest version of the rive Flutter package
• I have searched the documentation and forums and could not find an answer
• I have searched existing issues and this is not a duplicate

Description

I’m running into an issue on GitHub Actions where jobs using Ubuntu 22.04 fail to load the dynamic library librive_native.so, even after running dart run rive_native:setup --verbose --clean --platform linux.

Ubuntu 24.04 does not appear to have this issue, and the tests pass there without any problems.

The failure was first identified on my company’s self-hosted custom runners, which are based on Ubuntu 22.04. Since those runners cannot be upgraded for now, this issue is currently blocking us.

I’m aware that there is also a --build option, although I haven’t tested it yet. Since it requires additional system packages and tooling to be installed, I would prefer to avoid that route unless it is strictly necessary. Using the existing prebuilt binaries would be preferable.

I’ve attached screenshots from the runs available in my public repo, which I created specifically to reproduce the issue.

Additional context

The reported entry points are dart run rive_native:setup --verbose --clean --platform linux and flutter test; reproduce them on Ubuntu 22.04 in GitHub Actions and compare with Ubuntu 24.04. Done means the prebuilt librive_native.so loads and the tests pass without requiring --build.
