How To Use

    import 'package:flutter/material.dart';
    import 'dart:async';

    import 'package:flutter/services.dart';
    import 'package:flutter_youtube_downloader/flutter_youtube_downloader.dart';

    void main() {
      runApp(MyApp());
    }

    class MyApp extends StatefulWidget {
      @override
      _MyAppState createState() => _MyAppState();
    }

    class _MyAppState extends State<MyApp> {
      String _extractedLink = 'Loading...';

      String youTube_link = "https://www.youtube.com/watch?v=nRhYQlg8fVw";

      @override
      void initState() {
        super.initState();
        extractYoutubeLink();
      }

      // Platform messages are asynchronous, so we initialize in an async method.
      Future<void> extractYoutubeLink() async {
        String link;
        // Platform messages may fail, so we use a try/catch PlatformException.
        try {
          link = await FlutterYoutubeDownloader.extractYoutubeLink(youTube_link, 18);
        } on PlatformException {
          link = 'Failed to Extract YouTube Video Link.';
        }

        // If the widget was removed from the tree while the asynchronous platform
        // message was in flight, we want to discard the reply rather than calling
        // setState to update our non-existent appearance.
        if (!mounted) return;

        setState(() {
          _extractedLink = link;
        });
      }

      Future<void> downloadVideo() async {
        final result = await FlutterYoutubeDownloader.downloadVideo(
            youTube_link, "Video Title goes Here", 18);
        print(result);
      }

      @override
      Widget build(BuildContext context) {
        return MaterialApp(
          home: Scaffold(
            appBar: AppBar(
              title: const Text('Flutter Youtube Link Downloader example app'),
            ),
            body: Center(
              child: Text('Extracted Link : $_extractedLink\n'),
            ),
            floatingActionButton: FloatingActionButton(
              onPressed: downloadVideo,
              child: const Icon(Icons.download_rounded),
            ),
