Avoid regressions

Every code change will have to pass the CI with various checks and tons of tests (see the CI part of this page), so things are usually stable.

However, if you want to be 100% sure that your own use case will work forever, feel free to make a PR to add some tests for your scenario (mainly located in frb_example/pure_dart/).

This is in similar spirit as rfw, a package published by Flutter itself, quoted below:

We plan to keep the format and supported widget set backwards compatible, so that once a file works, it will keep working. However, this is best-effort only. To guarantee that files keep working as you expect, submit tests to this package (e.g. the binary file and the corresponding screenshot, as a golden test).
