Flutter – Implement a Simple VideoPlayer

To implement a simple video player in Flutter, you can use the video_player package, which allows you to play videos from various sources. In this article, we are going to see a step-by-step procedure to implement a VideoPlayer in a Flutter App. A sample video is given below to get an idea about what we are going to do in this article.

Required Tools

To build this app, you need the following items installed on your machine:

• Visual Studio Code / Android Studio
• Android Emulator / iOS Simulator / Physical Device device.
• Flutter Installed
• Flutter plugin for VS Code / Android Studio.

Step By Step Implementations

Step 1: Create a New Project in Android Studio

To set up Flutter Development on Android Studio please refer to Android Studio Setup for Flutter Development, and then create a new project in Android Studio please refer to Creating a Simple Application in Flutter.

Step 2 : Add the Required Dependency

Add the below dependency to your pubspec.yaml file.

dependencies:
  flutter:
    sdk: flutter
    video_player: ^2.2.15

Step 3: Import the Package

First of all import material.dart file.

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

Step 4: Execute the main Method

Here the execution of our app starts.

Dart

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

Step 5: Create MyApp Class

In this class we are going to implement the MaterialApp , here we are also set the Theme of our App.

Dart

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      theme: ThemeData(
        primarySwatch: Colors.green, // Set the app's primary theme color
      ),
      debugShowCheckedModeBanner: false,
      home: Scaffold(
        appBar: AppBar(
          title: Text('Video Player'),
        ),
        body: Center(
          child: VideoPlayerApp(),
        ),
      ),
    );
  }
}

Step 6: Create VideoPlayerApp Class

In this class we are going to Implement the Videoplayer that help to play a video in a flutter app. Comments are added for better understanding.

Dart

class VideoPlayerApp extends StatefulWidget {
  @override
  _VideoPlayerAppState createState() => _VideoPlayerAppState();
}

class _VideoPlayerAppState extends State<VideoPlayerApp> {
  VideoPlayerController? _controller;

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

    // Create a VideoPlayerController for the video you want to play.
    _controller = VideoPlayerController.network(
        'https://media.geeksforgeeks.org/wp-content/uploads/20230924220731/video.mp4');

    // Initialize the VideoPlayerController.
    _controller!.initialize();

    // Play the video.
    _controller!.play();
  }

  @override
  Widget build(BuildContext context) {
    return AspectRatio(
      aspectRatio: _controller!.value.aspectRatio,
      child: VideoPlayer(_controller!),
    );
  }

  @override
  void dispose() {
    super.dispose();

    // Dispose of the VideoPlayerController.
    _controller!.dispose();
  }
}

Here is the full Code of main.dart file

Dart

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

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      theme: ThemeData(
        primarySwatch: Colors.green, // Set the app's primary theme color
      ),
      debugShowCheckedModeBanner: false,
      home: Scaffold(
        appBar: AppBar(
          title: Text('Video Player'),
        ),
        body: Center(
          child: VideoPlayerApp(),
        ),
      ),
    );
  }
}

class VideoPlayerApp extends StatefulWidget {
  @override
  _VideoPlayerAppState createState() => _VideoPlayerAppState();
}

class _VideoPlayerAppState extends State<VideoPlayerApp> {
  VideoPlayerController? _controller;

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

    // Create a VideoPlayerController for the video you want to play.
    _controller = VideoPlayerController.network(
        'https://media.geeksforgeeks.org/wp-content/uploads/20230924220731/video.mp4');

    // Initialize the VideoPlayerController.
    _controller!.initialize();

    // Play the video.
    _controller!.play();
  }

  @override
  Widget build(BuildContext context) {
    return AspectRatio(
      aspectRatio: _controller!.value.aspectRatio,
      child: VideoPlayer(_controller!),
    );
  }

  @override
  void dispose() {
    super.dispose();

    // Dispose of the VideoPlayerController.
    _controller!.dispose();
  }
}

Output:
