Flutter video player in listview

Flutter Video Player in ListView

To implement a video player in a Flutter ListView, you can use the `video_player` package. This package provides a simple way to play videos in Flutter applications.

Step 1: Install the video_player package

You need to include the `video_player` package in your project’s `pubspec.yaml` file:

  
  dependencies:
    flutter:
      sdk: flutter
    video_player:
  
  

After adding the package, run the command `flutter pub get` to install it.

Step 2: Import the necessary dependencies

In the Dart file where you want to use the video player, import the required dependencies:

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

Step 3: Create a VideoPlayer widget

Now, create a Flutter widget that represents the video player. This can be done by extending the `StatefulWidget` class and overriding the `createState()` method:

  
  class VideoPlayerWidget extends StatefulWidget {
    final String videoUrl;
  
    VideoPlayerWidget({required this.videoUrl});
  
    @override
    _VideoPlayerWidgetState createState() => _VideoPlayerWidgetState();
  }
  
  class _VideoPlayerWidgetState extends State {
    late VideoPlayerController _controller;
    late Future _initializeVideoPlayerFuture;
  
    @override
    void initState() {
      super.initState();
      _controller = VideoPlayerController.network(widget.videoUrl);
      _initializeVideoPlayerFuture = _controller.initialize();
    }
  
    @override
    void dispose() {
      _controller.dispose();
      super.dispose();
    }
  
    @override
    Widget build(BuildContext context) {
      return FutureBuilder(
        future: _initializeVideoPlayerFuture,
        builder: (context, snapshot) {
          if (snapshot.connectionState == ConnectionState.done) {
            return AspectRatio(
              aspectRatio: _controller.value.aspectRatio,
              child: VideoPlayer(_controller),
            );
          } else {
            return Center(child: CircularProgressIndicator());
          }
        },
      );
    }
  }
  
  

In the above code, the `VideoPlayerWidget` class is responsible for creating and managing the video player. It takes a `videoUrl` parameter to specify the URL of the video to be played.

In the `initState()` method, we create an instance of the `VideoPlayerController` and initialize it with the given `videoUrl`. We also save the future returned by the `initialize()` method to ensure that the video player is fully initialized before displaying it.

In the `dispose()` method, we dispose of the video player controller to release resources when the widget is no longer used.

In the `build()` method, we use a `FutureBuilder` to handle the initialization process. If the `connectionState` is `done`, we display the `VideoPlayer` widget wrapped in an `AspectRatio` widget to maintain the video’s aspect ratio. Otherwise, we show a `CircularProgressIndicator` to indicate that the video player is being initialized.

Step 4: Use VideoPlayerWidget in ListView

Now, you can use the `VideoPlayerWidget` in a ListView. Here’s an example:

  
  class VideoListView extends StatelessWidget {
    final List videoUrls = [
      'https://www.example.com/video1.mp4',
      'https://www.example.com/video2.mp4',
      'https://www.example.com/video3.mp4',
    ];
  
    @override
    Widget build(BuildContext context) {
      return ListView.builder(
        itemCount: videoUrls.length,
        itemBuilder: (context, index) {
          return VideoPlayerWidget(videoUrl: videoUrls[index]);
        },
      );
    }
  }
  
  

In the above code, we define a `VideoListView` class that extends `StatelessWidget`. We have a list of video URLs and use a `ListView.builder` to create a ListView dynamically based on the number of video URLs.

For each video URL, we create an instance of the `VideoPlayerWidget` and pass the corresponding URL as a parameter.

Step 5: Add VideoListView to your app

Finally, you need to add the `VideoListView` widget to your app’s UI hierarchy. For example:

  
  class MyApp extends StatelessWidget {
    @override
    Widget build(BuildContext context) {
      return MaterialApp(
        title: 'Video Player in ListView',
        home: Scaffold(
          appBar: AppBar(title: Text('Video Player in ListView')),
          body: VideoListView(),
        ),
      );
    }
  }
  
  

In the above code, we define a `MyApp` class that extends `StatelessWidget` and sets the `VideoListView` as the `body` of the `Scaffold` widget.

Now, when you run the app, you should see a ListView with video players playing the videos from the given URLs.
