Low dependency modern bluetooth plugin written in swift and kotlin. The current implementation will only allow connecting to one bluetooth device at a time and only have one socket per uuid open.
In Android O this plugin leverages the Companion Device Manager which allows easy bluetooth device connections by pattern matching against available bluetooth devices and/or matching the service uuids reported by bluetooth devices.
There are tests for if bluetooth is supported await FlutterBluetooth.isSupported and if it is enabled await FlutterBluetooth.isEnabled. On android it is possible to enable bluetooth programatically, to do so await FlutterBluetooth.enable().
To connect to a device first call await FlutterBluetooth.connect() with the Device Attributes of the device you wish to connect to. Either the name pattern or a service uuid must be present.
Once the future returns a PairdDevice it's properties should be propagated with the device it connected with.
After connected to a device FlutterBluetooth.write() with socket data containing the uuid to write to and data to write will write to the provided uuid. FlutterBluetooth.read() with the socket uuid will provide a stream of byte arrays as they are returned by the device. If expecting a response from the device after a write, it is suggested the read stream be opened first.
Once you are done you can call FlutterBluetooth.disconnect() and all open sockets will be closed. Freeing flutter bluetooth resources.
