core_video_player 1.1.0

A customizable video player widget for Flutter.

core_video_player

A customizable video player widget for Flutter.

Built on top of video_player, core_video_player provides a ready-made layout and controls, plus extra functionality such as fullscreen, picture-in-picture, subtitles, Chromecast hooks, and automatic reconnection handling.

Features

• Playback controls (play/pause, seek, forward/rewind 10s, speed, resolution switching)
• Fullscreen mode
• Picture-in-picture (Android only)
• Subtitles (SRT and WebVTT)
• Keeps the screen on during playback
• Automatic connectivity checks and reconnection
• Chromecast UI hooks (click and layout events only — connection and playback are handled through your own Cast integration)
• Fully customizable icon set

Getting started

Add core_video_player to your pubspec.yaml:

dependencies:
  core_video_player:
    git:
      url: <your-repository-url>
      ref: master

Then install the dependency:

flutter pub get

Usage

import 'package:core_video_player/core_video_player.dart';

// Create a controller.
final playerController = CorePlayerController.init();

// (Optional) Register callbacks for player events.
playerController.events = CorePlayerEvents(
  onInitialized: (datasource) {},
  onPlay: (state) {},
);

// Set the video to be played.
playerController.changeDatasource(
  CorePlayerDatasource(
    title: 'My video',
    description: 'Video description',
    hasNext: false,
    hasPrev: false,
    resolutions: {
      CorePlayerResolution.p480: Uri.parse('https://example.com/video.mp4'),
    },
  ),
);

// Render the player.
CorePlayer(playerController)

Customizing icons

The default icons can be overridden through CorePlayerConfig:

final playerController = CorePlayerController.init(
  config: CorePlayerConfig(
    icons: CorePlayerIcons(
      arrow_back: CoreIconData(Icons.arrow_back_ios, size: 20, color: Colors.white),
    ),
  ),
);
