Video Player With Cache Capability
Video Player plugin for Flutter #
A Flutter plugin Android for playing back video on a Widget surface.
Installation #
First, add cache_video_player
as a dependency in your pubspec.yaml file.
Android #
Ensure the following permission is present in your Android Manifest file, located in <project root>/android/app/src/main/AndroidManifest.xml
:
<uses-permission android:name="android.permission.INTERNET"/>
The Flutter project template adds it, so it may already be there.
Supported Formats #
Example #
import 'package:video_player/cache_video_player.dart';
import 'package:flutter/material.dart';
void main() => runApp(VideoApp());
class VideoApp extends StatefulWidget {
@override
_VideoAppState createState() => _VideoAppState();
}
class _VideoAppState extends State<VideoApp> {
VideoPlayerController _controller;
@override
void initState() {
super.initState();
_controller = VideoPlayerController.network(
'https://flutter.github.io/assets-for-api-docs/assets/videos/bee.mp4')
..initialize().then((_) {
// Ensure the first frame is shown after the video is initialized, even before the play button has been pressed.
setState(() {});
});
}
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Video Demo',
home: Scaffold(
body: Center(
child: _controller.value.isInitialized
? AspectRatio(
aspectRatio: _controller.value.aspectRatio,
child: VideoPlayer(_controller),
)
: Container(),
),
floatingActionButton: FloatingActionButton(
onPressed: () {
setState(() {
_controller.value.isPlaying
? _controller.pause()

Usage #
The following section contains usage information that goes beyond what is included in the documentation in order to give a more elaborate overview of the API.
This is not complete as of now. You can contribute to this section by opening a pull request.
Playback speed #
You can set the playback speed on your _controller
(instance of VideoPlayerController
) by
calling _controller.setPlaybackSpeed
. setPlaybackSpeed
takes a double
speed value indicating
the rate of playback for your video.
For example, when given a value of 2.0
, your video will play at 2x the regular playback speed
and so on.
To learn about playback speed limitations, see the setPlaybackSpeed
method documentation.
Furthermore, see the example app for an example playback speed implementation.
