Use the WinBle plugin to enable Bluetooth Low Energy in Flutter Windows and pure Dart projects (Windows only)
First initialize WinBle, to initialize on Flutter Windows, get server path using await WinServer.path, and for pure dart projects ( Windows only ) Download BleServer.exe file and place in the same folder, checkout example_dart for more details
// To initialize on Flutter Windows
await WinBle.initialize(serverPath: await WinServer.path());
// For pure dart projects
await WinBle.initialize(serverPath: "Path of BLEServer.exe file");Dispose WinBle after using
WinBle.dispose();To Start Scan
WinBle.startScanning();
StreamSubscription? scanStream = WinBle.scanStream.listen((event) {
// Get Devices Here
});To Stop Scan
WinBle.stopScanning();
scanStream?.cancel();To Connect
// To Connect
await WinBle.connect(address);
// Get Connection Updates Here
StreamSubscription _connectionStream =
WinBle.connectionStreamOf(device.address).listen((event) {
// event will be a boolean , in which
// true => Connected
// false => Disconnected
});To Disconnect
await WinBle.disconnect(address);To get MaxMtuSize
await WinBle.getMaxMtuSize(address);Handle Bluetooth radio
// To get rdaio status
WinBle.getBluetoothState();
// To get updates of radio state
WinBle.bleState.listen((BleState state) {
// Get BleState (On, Off, Unknown, Disabled, Unsupported)
});
// To turn on radio
WinBle.updateBluetoothState(true);
// To turn off radio
WinBle.updateBluetoothState(false);Pairing Options
// To Pair
await WinBle.pair(address);
// To UnPair
await WinBle.unPair(address);
// To Check if Device can be Paired
bool canPair = await WinBle.canPair(address);
// To Check if Device is Already Paired
bool isPaired = await WinBle.isPaired(address);Rest All Methods are
// To Get Services
var services = await WinBle.discoverServices(address);
// To Get Characteristic
List<BleCharacteristic> bleCharacteristics = await WinBle.discoverCharacteristics(address: address, serviceId: serviceID);
// To Read Characteristic
List<int> data = await WinBle.read(address: address, serviceId: serviceID, characteristicId: charID);
// To Write Characteristic
await WinBle.write( address: address, service: serviceID, characteristic: charID, data: data, writeWithResponse: writeWithResponse);
// To Start Subscription
await WinBle.subscribeToCharacteristic(address: address, serviceId: serviceID, characteristicId: charID);
// To Stop Subscription
await WinBle.unSubscribeFromCharacteristic(address: address, serviceId: serviceID, characteristicId: charID);
// Get Characteristic Value Updates Here
StreamSubscription _characteristicValueStream = WinBle.characteristicValueStream.listen((event) {
// Here We will Receive All Characteristic Events
});

If windows release build opens cmd while running app, try this
Edit your /windows/runner/main.cpp file, this is a known flutter issue
