Video Maestro

Video Maestro 🎬

A powerful, customizable, and feature-rich Flutter video player package built on top of video_player. Video Maestro removes the boilerplate of building a video player UI from scratch — giving you smart auto-detected sources, gesture controls, captions, full-screen, theming, and localization out of the box.

Installation

Add the package to your pubspec.yaml:

dependencies:
  video_maestro: ^0.0.1

Then run:

flutter pub get

---

Quick Start

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

class MyVideoScreen extends StatefulWidget {
  const MyVideoScreen({super.key});

  @override
  State<MyVideoScreen> createState() => _MyVideoScreenState();
}

class _MyVideoScreenState extends State<MyVideoScreen> {
  late final MaestroController _controller;

  @override
  void initState() {
    super.initState();
    _controller = MaestroController(
      url: 'https://www.example.com/sample_video.mp4',
    );
    _controller.initialize();
  }

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

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: Colors.black,
      body: Center(
        child: VideoMaestro(
          controller: _controller,
        ),
      ),
    );
  }
}

Important: VideoMaestro requires a VideoMaestroTheme extension to be present in the current ThemeData. See Theming for setup.

MaestroController

MaestroController is the single entry point for all video operations. Create one instance per player and pass it to VideoMaestro.

Creating a controller

// Network URL
final controller = MaestroController(url: 'https://example.com/video.mp4');

// Asset
final controller = MaestroController(url: 'assets/videos/intro.mp4');

// Local file path
final controller = MaestroController(url: '/storage/emulated/0/video.mp4');

// Provide your own VideoPlayerController
final controller = MaestroController(
  url: 'https://example.com/video.mp4',
  videoPlayerController: myExistingController,
);

Source type (network / asset / file) is auto-detected from the string. You never need to specify it manually.

Lifecycle

// Initialize and start loading
await controller.initialize();

// Playback
controller.play();
controller.pause();

// Seek to a position
await controller.seekTo(const Duration(seconds: 30));

// Always dispose when done
controller.dispose();

State stream

MaestroController exposes a BehaviorSubject you can listen to:

StreamBuilder<VideoMaestroState>(
  stream: controller.playerStateNotifier,
  builder: (context, snapshot) {
    return switch (snapshot.data) {
      VideoMaestroInitialState()  => const SizedBox(),
      VideoMaestroLoadingState()  => const CircularProgressIndicator(),
      VideoMaestroSuccessState()  => const Text('Playing'),
      VideoMaestroFailureState(:final message) => Text('Error: $message'),
      null => const SizedBox(),
    };
  },
);

State	Meaning
VideoMaestroInitialState	Controller created, not yet initialized
VideoMaestroLoadingState	initialize() called, loading in progress
VideoMaestroSuccessState	Video ready to play
VideoMaestroFailureState	Initialization failed (optional error message)

Useful getters

Getter	Type	Description
isPlaying	bool	Whether the video is currently playing
playerController	VideoPlayerController	Direct access to the underlying controller
captionLoaderHelper	CaptionLoaderHelper	Manages caption loading and switching
playerStateNotifier	BehaviorSubject<VideoMaestroState>	Observable state stream
isInFullScreenNotifier	BehaviorSubject<bool>	Tracks full-screen state

---

VideoMaestroConfig

VideoMaestroConfig is passed to VideoMaestro to configure behavior and visible elements.

VideoMaestro(
  controller: _controller,
  config: VideoMaestroConfig(
    doubleTapSeekTime: 10, // Seek ±10 s on double-tap (default: 5)
    optionsVisibility: OptionsVisibilityControl(
      showSpeedButton: true,
      showFullScreenButton: true,
      doubleTapToSeek: true,
      holdToDoubleSpeed: true,
      showCaptions: true,
    ),
    captions: [
      CaptionData(name: 'English', path: 'assets/en.vtt'),
    ],
    bufferLoader: const CircularProgressIndicator(strokeWidth: 3),
    extraBottomButtons: [
      IconButton(icon: const Icon(Icons.share), onPressed: _shareVideo),
    ],
    onVideoWidgets: [
      const Positioned(top: 12, right: 12, child: MyBadgeWidget()),
    ],
  ),
)

Config properties

Property	Type	Default	Description
doubleTapSeekTime	int?	5	Seconds to seek on double-tap
optionsVisibility	OptionsVisibilityControl	all true	UI toggle flags
captions	List<CaptionData>?	null	Subtitle tracks to offer
bufferLoader	Widget	CircularProgressIndicator	Widget shown while buffering
extraBottomButtons	List<Widget>?	null	Extra icons appended to the bottom bar
onVideoWidgets	List<Widget>?	null	Widgets stacked on top of the video (use Positioned)

Separate full-screen config

You can provide a different config when the player enters full screen:

VideoMaestro(
  controller: _controller,
  config: VideoMaestroConfig(doubleTapSeekTime: 5),
  fullScreenConfig: VideoMaestroConfig(
    doubleTapSeekTime: 15,
    optionsVisibility: OptionsVisibilityControl(showCaptions: false),
  ),
)

---

OptionsVisibilityControl

Fine-tune which UI elements are visible.

// Show everything (default)
const OptionsVisibilityControl()

// Custom combination
const OptionsVisibilityControl(
  showSpeedButton: false,
  showFullScreenButton: true,
  doubleTapToSeek: true,
  holdToDoubleSpeed: false,
  showCaptions: true,
)

Flag	Default	Description
showSpeedButton	true	Speed icon in the bottom bar
showFullScreenButton	true	Full-screen toggle icon
doubleTapToSeek	true	Double-tap left/right to seek
holdToDoubleSpeed	true	Long-press to play at 2×
showCaptions	true	Caption text overlay + captions icon

---

Captions

Video Maestro has a built-in CaptionLoaderHelper that handles loading, caching, and switching between multiple subtitle tracks.

Supported formats

• WebVTT (.vtt)
• SubRip (.srt)

Supported sources

• App assets
• Local file paths
• Network URLs (downloaded, cached to disk, deduplicated)

Setting up captions

VideoMaestroConfig(
  captions: [
    // From asset (type auto-detected from extension)
    CaptionData(name: 'English', path: 'assets/captions/en.vtt'),

    // From network
    CaptionData(name: 'Arabic', path: 'https://example.com/ar.srt'),

    // Explicit type
    CaptionData(
      name: 'French',
      path: 'assets/fr_captions',
      type: CaptionTypeEnum.vtt,
    ),
  ],
)

• If one caption track is provided, it is loaded and applied automatically.
• If multiple tracks are provided, a bottom sheet is shown when the user taps the caption icon, allowing them to pick a track or remove captions.

CaptionData fields

Field	Type	Description
name	String	Display name shown in the selection sheet
path	String	Asset path, file path, or network URL
type	CaptionTypeEnum?	vtt or srt — auto-detected from extension if omitted

Using CaptionLoaderHelper directly

// Load and apply a track programmatically
await controller.captionLoaderHelper.loadAndApply(
  const CaptionData(name: 'English', path: 'assets/en.vtt'),
);

// Remove the active caption
await controller.captionLoaderHelper.clearCaption();

// Check if a path is the currently active caption
final bool active = controller.captionLoaderHelper.isActive('assets/en.vtt');

// Observe the active caption
ValueListenableBuilder<CaptionData?>(
  valueListenable: controller.captionLoaderHelper.activeCaptionNotifier,
  builder: (context, caption, _) => Text(caption?.name ?? 'No caption'),
);

---

Theming

Video Maestro integrates with Flutter's ThemeExtension system. Add VideoMaestroTheme to your app's ThemeData (this is required.)

Basic setup

MaterialApp(
  theme: ThemeData(
    extensions: const [
      VideoMaestroTheme(), // All defaults — dark player on black background
    ],
  ),
  home: MyVideoScreen(),
)

Full customization

MaterialApp(
  theme: ThemeData(
    extensions: [
      VideoMaestroTheme(
        // Background
        backgroundColor: Colors.black,

        // Icons
        iconColor: Colors.white,
        iconSize: 26,

        // Seek overlay (double-tap animation)
        seekOverlayGradient: [Colors.black12, Colors.black38],
        seekOverlayIconColor: Colors.white70,
        seekOverlayIconSize: 34,

        // Bottom controls gradient
        controlsBarGradient: [Colors.transparent, Colors.black54, Colors.black87],

        // Progress / seek bar
        seekBarTrackColor: Colors.black45,
        seekBarBufferColor: Color(0x64757575),
        sliderThemeData: SliderThemeData(
          trackHeight: 4,
          thumbShape: FlatThumbShape(thumbRadius: 8),
          overlayColor: Colors.transparent,
          inactiveTrackColor: Colors.white24,
        ),

        // Time labels
        timePositionStyle: TextStyle(color: Colors.white, fontSize: 14, fontWeight: FontWeight.w500),
        timeDurationStyle: TextStyle(color: Color(0xDCFFFFFF), fontSize: 14),

        // Floating time tooltip
        floatingTimeBackgroundColor: Colors.black26,
        floatingTimeTextStyle: TextStyle(fontSize: 12, color: Colors.white),

        // Captions
        captionTextStyle: TextStyle(fontSize: 15, color: Colors.white),

        // 2× speed badge shown during long-press
        doubleSpeedBadgeView: MaestroDoubleSpeedView(),

        // Device orientations to restore after exiting full screen
        appPreferredOrientations: [DeviceOrientation.portraitUp],
      ),
    ],
  ),
)

Per-widget theme override

Use VideoMaestroThemeOverrider to override the theme for a specific VideoMaestro widget without touching the global theme:

VideoMaestroThemeOverrider(
  data: (isDark, current) => current.copyWith(
    backgroundColor: isDark ? Colors.grey[900]! : Colors.white,
    iconColor: isDark ? Colors.white : Colors.black,
  ),
  child: VideoMaestro(controller: _controller),
)

The data callback receives:

• isDark — whether the current ThemeData is dark
• current — the currently resolved VideoMaestroTheme, so you can use .copyWith() to change only what you need

captionTextStyle	TextStyle?	white, 14sp
doubleSpeedBadgeView	Widget	MaestroDoubleSpeedView()
appPreferredOrientations	List<DeviceOrientation>	All orientations

FlatThumbShape

A custom SliderComponentShape included in the package that renders a flat circular thumb for the seek bar. Configurable via thumbRadius.

sliderThemeData: SliderThemeData(
  thumbShape: FlatThumbShape(thumbRadius: 6),
)

---

Localization

Video Maestro reads the Locale from Flutter's Localizations widget. English and Arabic are built in.

Setup

MaterialApp(
supportedLocales: const [
Locale('en'),
Locale('ar'),
],
localizationsDelegates: const [
GlobalMaterialLocalizations.delegate,
GlobalWidgetsLocalizations.delegate,
GlobalCupertinoLocalizations.delegate,
],
// ...
)

No additional delegate registration is required for Video Maestro itself — it hooks into the existing Localizations.localeOf(context).

---

Bottom Sheets

Video Maestro provides two ready-made modal bottom sheets accessible via MaestroBottomSheets. They are already wired into the default bottom controls bar, but you can invoke them manually too.

Speed sheet

await MaestroBottomSheets.openSpeedBottomSheet(
context: context,
controller: _controller,
// Optional route settings for navigator-based dismissal
routeSettings: const RouteSettings(name: 'maestro-speed-bottom-sheet'),
);

• Displays an interactive slider from 0.25× to 2.0× (step: 0.05×).
• Speed is applied live as the thumb is dragged.
• Video is automatically paused before opening and resumed after closing.

Captions sheet

await MaestroBottomSheets.openCaptionsBottomSheet(
context: context,
controller: _controller,
captions: myCaptionList,
routeSettings: const RouteSettings(name: 'maestro-captions-bottom-sheet'),
);

• Lists all available caption tracks.
• The active track is highlighted with a check mark.
• Includes a Remove Caption option when a caption is active.
• Video is paused/resumed automatically.

---

Full Screen

Full-screen mode is handled internally via VideoMaestroFullScreen. Tapping the full-screen icon in the bottom bar pushes a new route that forces landscape orientation.

// Entering full screen is done automatically via the button.
// To control orientations restored after exiting, configure:
VideoMaestroTheme(
appPreferredOrientations: [DeviceOrientation.portraitUp],
)

You can also pass a distinct fullScreenConfig to VideoMaestro so the full-screen player has different settings (e.g., larger seek increments, hidden captions):

VideoMaestro(
controller: _controller,
config: VideoMaestroConfig(doubleTapSeekTime: 5),
fullScreenConfig: VideoMaestroConfig(doubleTapSeekTime: 30),
)
