Getting Started

For a full example please check /example folder. Here are only the most important parts of the code to illustrate how to use the library.

//Initiatinng the bluetooth adapter
Bluetoothadapter flutterbluetoothadapter = Bluetoothadapter();

//Listening to the connection status listener
String _connectionStatus = "NONE";
StreamSubscription _btConnectionStatusListener =flutterbluetoothadapter.connectionStatus().listen((dynamic status) {
  setState(() {
    _connectionStatus = status.toString();
  });
});

//Listening to the recieved messages
String _recievedMessage;
StreamSubscription _btReceivedMessageListener = flutterbluetoothadapter.receiveMessages().listen((dynamic newMessage) {
  setState(() {
    _recievedMessage = newMessage.toString();
  });
});

Getting paired devices

List<BtDevice> devices = await flutterbluetoothadapter.getDevices();

Getting paired device

await flutterbluetoothadapter.getDevice(deviceAddress);

Starting BT server

await flutterbluetoothadapter.startServer();

Starting BT client

flutterbluetoothadapter.startClient(devices.indexOf(element), true);

Sending message

flutterbluetoothadapter.sendMessage(messageString);

Check BT connection

await flutterbluetoothadapter.checkBluetooth(); //returns bool

Set UUID

flutterbluetoothadapter.initBlutoothConnection(uuid);
