### Describe the bug
I read your code on how ```Pedometer.pedestrianStatusStream``` return stream on Android, and see that ```_androidPedestrianStreamController``` currently does not handle incoming error.
Current version:

### To Reproduce
Using device with no StepDetection to test steam error handling.

### Expected behavior
Should add addError to ```_androidPesdetrianStreamController``` so that it can be handle when create streamSubscription with Pedometer.pedestrianStream.listen().onError((e) {})

### Actual behavior
Error being log as UnhandledException and ```Pedometer.pedestrianStatusStream.listen().onError((e) {})``` can not catch this error.
