Well done! I've heard only good things about rust_flutter_bridge. Some questions though (more like flutter question), how bloated flutter is (i.e. final app size) compared to mobile native (Java, Swift?) for simple app? And how's the UI performance looks like?
For app size, it depends on your specific scenario, because e.g. Flutter automatically removes library code that is not used. I remembered (but the memory is blur) simple app has something like ~5MB. Btw remember to split .so file per abi. For UI performance, I personally find it quite good, and Flutter(Dart) is compiled to assembly code via AOT (instead of e.g. JIT or interpreted), which theoretically speaking is also fast. For both, I would suggest to make a demo for your specific case to have more accurate results. Also I guess ask/discuss on the Flutter community may help.
