Create Stream of Screenshot stream and listen call back path

    Future<void> _listenScreenShot() async {
    _stream = _screenshotDetect.screenShotStream();

    _stream.listen((String? path) {
      print("It's a screenshot of the path!\n $path");
    }).onError((error) {
      print("It's somethings wrong: \n $error");
    });
  }

Full example

import 'package:screenshot_detect_plugin_flutter/screenshot_detect.dart';

class _MyAppState extends State<MyApp> {
  final ScreenshotDetect _screenshotDetect = ScreenshotDetect();
  late Stream<String?> _stream;

  @override
  void initState() {
    super.initState();
    _checkPermission();
    _listenScreenShot();
  }

  Future<void> _checkPermission() async {
    _screenshotDetect.checkPermission().then((isGranted) {
      if (isGranted == null || !isGranted) {
        _screenshotDetect.requestPermission();
      }
    });
  }

  Future<void> _listenScreenShot() async {
    _stream = _screenshotDetect.screenShotStream();

    _stream.listen((String? path) {
      print("It is a path screenshot!\n $path");
    }).onError((error) {
      print("It is somethings wrong: \n $error");
    });
  }

   @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Screenshot example app'),
        ),
        body: SizedBox(
          width: double.infinity,
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            crossAxisAlignment: CrossAxisAlignment.center,
            children: [
              Text('Running on: $_platformVersion\n'),
              StreamBuilder<String?>(
                stream: _stream,
                builder: (_, AsyncSnapshot<String?> snapshoot) {
                  if (snapshoot.data == null) {
                    return const Text('Let\'s take screenShot now!');

                      height: 200,
                      child: Image.file(File(snapshoot.data!)));
                },
              ),
