Flutter Rive on iOS stopped Working

[vilorel]

Description

All the rive animations stopped working on iOS -- we see a blank screen.

Steps To Reproduce

The following halts execution; it cannot get past this point.
await RiveFile.asset(path);

Both the following and network animations also don't work. It shows a blank widget, no errors or warnings:

return rive.RiveAnimation.asset(path,
          antialiasing: true,
          fit: BoxFit.fill,
        );

Source .riv/.rev file

We tried different files, some old and some that we generated yesterday. We tried simple animations, and they don't work.

Expected behavior

We expect the animation to work on iOS instead of seeing nothing.

Screenshots

No screenshots are necessary as you just see a blank screen.

Additional context

By the way, the animations DO work on both Android and the web without any issues.

It was not a rive issue after all, my Flutter workspace has been upgraded too many times and it needed a fresh restart. Once I ported my existing code into a new clean project, everything worked like a charm.
