Question about flutter `Isolate`

[Chengxi Gu]

I was using Isolate to upload files with v1.82.6 and it worked fine. But after I upgrade frb to 2.0.0.dev.21, when I use Isolate, it throws
should init Rustlib. I have inited RustLib in main function. I have 2 questions.

1. should I init RustLib everytime in a new Isolate?
2. should I dispose RustLib after works done in Isolate?

Good question - I should add the multi-isolate scenario in the tests and in the doc. Before that, here is my quick guess: Try to init in new isolate. As for disposal, it would be great to do; if it is not disposed, I am not sure whether dart isolate cleanup is smart enough or not to cleanup all related dart resources. Anyway, it seems to be a common style to dispose() everything in Flutter (e.g. dispose ui.Image, widget controllers, etc)

I see. Thanks for the answer.
