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,
),
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();
_controller = VideoPlayerController.network(
_controller!.initialize();
_controller!.play();
}
@override
Widget build(BuildContext context) {
return AspectRatio(
aspectRatio: _controller!.value.aspectRatio,
child: VideoPlayer(_controller!),
);
}
@override
void dispose() {
super.dispose();
_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,
),
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();
_controller = VideoPlayerController.network(
_controller!.initialize();
_controller!.play();
}
@override
Widget build(BuildContext context) {
return AspectRatio(
aspectRatio: _controller!.value.aspectRatio,
child: VideoPlayer(_controller!),
);
}
@override
void dispose() {
super.dispose();
_controller!.dispose();
}
}
