bluetooth_state_manager

The Bluetooth State Manager package only meets the needs of those who want to monitor the bluetooth status.The example scenario is to separate the state process from the processes done in its native layer instead of using other Bluetooth packages.

android/app/src/main/AndroidManifest.xml

    xmlns:tools="http://schemas.android.com/tools"
    package="com.example">
    <uses-permission android:name="android.permission.BLUETOOTH_CONNECT"/>
    <uses-permission android:name="android.permission.BLUETOOTH"/>
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>

You only need add the permission message on the Info.plist

	<key>NSBluetoothAlwaysUsageDescription</key>
	<string>NSBluetoothAlwaysUsageDescription</string>

Usage/Examples

main.dart

class _MyAppState extends State<MyApp> {
  final bluetoothManager = BluetoothManager();
  bool? isBleEnable;
  late Stream<bool> bluetoothManagerSubs;
  @override
  void initState() {
    bluetoothManagerSubs = bluetoothManager.listenBleState();
    if (isBleEnable == null) {
      bluetoothManager.onBle();
    }
    bluetoothManagerSubs.listen((event) {
      setState(() {
        isBleEnable = event;
      });
    });
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Plugin example app'),
        ),
        body: Center(
          child: Column(
            children: [
              Text('BLE STATUS: $isBleEnable\n'),
              ElevatedButton(onPressed: () => bluetoothManager.onBle(), child: const Text("On")),
              ElevatedButton(onPressed: () => bluetoothManager.offBle(), child: const Text("Off"))
            ],
          ),
        ),
      ),
    );
  }
