goto your project -> android -> app -> src -> package name -> AndroidManifest.xml and paste the below code before tag begins.. then stop the app and run again

<uses-permission android:name="android.permission.BLUETOOTH" /> <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" /> <uses-permission android:name="android.permission.BLUETOOTH_ADVERTISE" /> <uses-permission android:name="android.permission.BLUETOOTH_CONNECT" /> <uses-permission android:name="android.permission.BLUETOOTH_SCAN" /> <uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />

Try checking for permission

  void initBTprinter() async {
    await Permission.bluetoothScan.isDenied.then((value) {
if (value) {
  Permission.bluetoothScan.request();
  printerManager.startScan(Duration(seconds: 2));
}
});
}
