State listen event not firing

[andydean565]

cant get the listen event to fire for the Bluetooth state, tried it on my own project but after trying for a while downloaded the example and get the same issue.

if I run the following after trying to connect to a device it does show that iv been connected but no event from the listener.

` bool isConnected = await bluetoothManager.isConnected;

this is coming up in the console:
