discoverServices method

Future<List<BluetoothService>> discoverServices({ bool subscribeToServicesChanged = true, int timeout = 15, })

Discover services, characteristics, and descriptors of the remote device

• subscribeToServicesChanged Android Only: If true, after discovering services we will subscribe to the Services Changed Characteristic (0x2A05) used for the device.onServicesReset stream. Note: this behavior happens automatically on iOS and cannot be disabled

Implementation
