universal_video_controls 1.0.7

Video player controls for all platforms based on media_kit controls but with abstraction to allow any other player to work using it (video_player is supported)

universal_video_controls

Overview

The universal_video_controls package provides a comprehensive solution for video controls that can be universally applied to various video players. This package is a port and generalization of the media_kit controls, designed to create an abstraction that allows these controls to work with any video player backend, provided that the backend's interface is compatible with the AbstractPlayer class.

Getting Started

This section will guide you through the steps to get started with the universal_video_controls package.

Installation

Add the following dependencies to your pubspec.yaml file:

dependencies:
  universal_video_controls: ^1.0.6
  universal_video_controls_video_player: ^1.0.1
  video_player: ^2.2.5

Then run flutter pub get to install the packages.

Usage

To use the universal_video_controls package, you need to integrate it with a video player backend that implements the AbstractPlayer interface. Here is a minimal example demonstrating how to set up and use the universal_video_controls with the video_player package.

Example: Single Player Single Video

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

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: SinglePlayerSingleVideoScreen(),
    );
  }
}

class SinglePlayerSingleVideoScreen extends StatefulWidget {
  @override
  State<SinglePlayerSingleVideoScreen> createState() => _SinglePlayerSingleVideoScreenState();
}

class _SinglePlayerSingleVideoScreenState extends State<SinglePlayerSingleVideoScreen> {
  late VideoPlayerController _controller;
  bool _isInitialized = false;

  @override
  void initState() {
    super.initState();
    _initializeVideoPlayer('https://www.example.com/video.mp4');
  }

  void _initializeVideoPlayer(String source) async {
    _controller = VideoPlayerController.network(source);
    await _controller.initialize();
    setState(() {
      _isInitialized = true;
    });
    _controller.play();
    _controller.addListener(() {
      if (_controller.value.hasError) {
        debugPrint(_controller.value.errorDescription);
      }
    });
  }

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

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Video Player'),
      ),
      body: Center(
        child: _isInitialized
            ? AspectRatio(
                aspectRatio: _controller.value.aspectRatio,
                child: VideoControls(
                  player: VideoPlayerControlsWrapper(_controller),
                ),
              )
            : const CircularProgressIndicator(),
      ),
    );
  }
}

Select existing video controls

Modify the controls argument. For advanced theming of existing video controls, see theming & modifying video controls section.

Scaffold(
  body: VideoControls(
    controller: controller,
    // Select [MaterialVideoControls].
    controls: MaterialVideoControls,
  ),
);

Scaffold(
  body: VideoControls(
    controller: controller,
    // Select [CupertinoVideoControls].
    controls: CupertinoVideoControls,
  ),
);

Build custom video controls

Pass custom builder Widget Function(BuildContext, VideoController) as controls argument.

Scaffold(
  body: VideoControls(
    controller: controller,
    // Provide custom builder for controls.
    controls: (state) {
      return Center(
        child: IconButton(
          onPressed: () {
            state.widget.controller.player.playOrPause();
          },
          icon: StreamBuilder(
            stream: state.widget.controller.player.stream.playing,
            builder: (context, playing) => Icon(
              playing.data == true ? Icons.pause : Icons.play_arrow,
            ),
          ),
          // It's not necessary to use [StreamBuilder] or to use [Player] & [VideoController] from [state].
          // [StreamSubscription]s can be made inside [initState] of this widget.
        ),
      );
    },
  ),
);
