A Flutter plugin to expose the features of Bluetooth Adapter for Android only.
Objective #
The primary purpose of this project was to communicate between flutter and paired Wear OS devices using Bluetooth. It is developed based on the code of bluetoothadapter package and the only ideal was to make it in compliance with null-safety.
Main Features #

Setting up a UUID from user end.
Checking Bluetooth connection status and giving alerts if its off or not right.
Getting list of paired devices.
Get a particular paired device info.
Start Bluetooth server.
Start Bluetooth client.
Start Bluetooth client.
Send message to a connected device.
Stream for listening to received messages.
Stream for listening to connection status (CONNECTED, CONNECTING, CONNECTION FAILED, LISTENING, DISCONNECTED).

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
BluetoothConnector flutterbluetoothconnector = BluetoothConnector();

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

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