Hot restarting is broken due to all the stuff going on with isolates and especially native Android services. Hot restarting will never work because IIRC Flutter doesn't stop native services.

(Correct me if I'm wrong @ryanheise , but I'm pretty sure this is why it's not worth bothering to fix any hot restarting issues.)

[ryanheise]

Yes, it's an unfortunate limitation of Flutter. Maybe the Flutter team could improve the situation if you open an issue with them. Even though it would not be practical to hot restart or reload the native code, they should at least be able to reconnect the method channels between the native code and the new isolates.

I'll close this as unfixable.
