onAvailabilityChanged static method
Get a Stream for the availability of a Bluetooth adapter. If a user inserts or removes a bluetooth adapter from their devices this stream will update. It will not necessarily update if the user enables/ disables a bluetooth adapter.
Implementation
static Stream<bool> onAvailabilityChanged() {
if (!isBluetoothAPISupported()) {
return Stream.value(false);
}
if (_availabilityStream != null) {
return _availabilityStream!.stream;
}
_availabilityStream = WebBehaviorSubject();
_nativeBluetooth.availabilityChanged.listen((final event) {
final value = event.value.toDart;
_availabilityStream?.add(value);
});
unawaited(getAvailability());
return _availabilityStream!.stream;
}
