A Flutter package for creating smooth video splash screens using media_kit. Provides seamless transitions from native splash screens to video playback with flexible overlay support and manual controls.
## Platform Support

## Features
- ✨ **Smooth Transitions** - Defer first frame pattern prevents jank between native and video splash

- 🔄 **Looping Support** - Infinite video loops with user-controlled exit
- 📱 **Flexible Overlays** - Title, footer, and custom overlay widgets
- 🎯 **Auto-Navigation** - Automatic screen transitions or manual control
- 🎨 **Customizable** - Aspect ratio, fullscreen, volume, and more
- 🎨 **7 Scale Modes** - Cover, contain, fill, fitWidth, fitHeight, scaleDown, none

### Video Scale Modes
Control how your video fills the screen with 7 different scale modes:
```dart
SplashVideo(
source: AssetSource('assets/videos/splash.mp4'),
nextScreen: HomeScreen(),
videoConfig: VideoConfig(
fitMode: VideoFitMode.cover, // Fill screen, may crop edges (best for splash)
),
)
```
**Available Scale Modes:**
- `VideoFitMode.cover` - Fill screen, maintain aspect, may crop (recommended for splash screens)
- `VideoFitMode.contain` - Fit inside, maintain aspect, may show letterboxing
- `VideoFitMode.fill` - Stretch to fill (ignores aspect ratio, may distort)
- `VideoFitMode.fitWidth` - Match width, maintain aspect
- `VideoFitMode.fitHeight` - Match height, maintain aspect
- `VideoFitMode.scaleDown` - Like contain but won't upscale beyond original size
- `VideoFitMode.none` - Original size, centered
**Quick Comparison:**
| Fit Mode | Best For | Maintains Aspect | May Crop | May Letterbox |
|----------|----------|------------------|----------|---------------|
| `cover` | Splash screens, hero sections | ✅ | ✅ | ❌ |
| `contain` | Viewing entire video | ✅ | ❌ | ✅ |
| `fill` | Exact fill (rare) | ❌ | ❌ | ❌ |
| `fitWidth` | Horizontal content | ✅ | Vertical | Horizontal |
| `fitHeight` | Vertical content | ✅ | Horizontal | Vertical |
| `scaleDown` | Small videos | ✅ | ❌ | ✅ |
| `none` | Pixel-perfect display | ✅ | ❌ | ✅ |

videoVisibilityEnum: VisibilityEnum.useFullScreen, // Display mode
fitMode: VideoFitMode.cover, // How video fills screen (7 modes)
useSafeArea: false, // Wrap in SafeArea

volume: 80.0, // Volume (0-100), default 80
enableAudio: true, // Enable/disable audio track
onPlayerInitialized: (player) { },// Player ready callback
)
```
**Parameters:**
- `playImmediately` (bool) - Start playing immediately after load. Default: `true`
- `fitMode` (VideoFitMode) - Video sizing strategy. Default: `VideoFitMode.cover`
- `useSafeArea` (bool) - Avoid notches and system UI. Default: `false`
- `volume` (double) - Initial volume 0-100. Default: `80.0`
- `enableAudio` (bool) - Enable audio track (more efficient than volume=0). Default: `true`
- `onPlayerInitialized` (Function?) - Callback when Player is ready

### VisibilityEnum
## Migration Guide
### From v0.0.1 to v0.0.2+
The `VideoAspectRatio` enum has been replaced with `VideoFitMode` for better video sizing control:
**Old API (Deprecated but still works):**
```dart
VisibilityEnum.useFullScreen // Fill entire screen
VisibilityEnum.useAspectRatio // Maintain aspect ratio
VisibilityEnum.none // No special sizing
VideoConfig(
videoVisibilityEnum: VideoAspectRatio.useFullScreen,
)
```
**New API (Recommended):**
```dart
VideoConfig(
fitMode: VideoFitMode.cover,
)
```
**Migration Table:**
| Old API | New API | Notes |
|---------|---------|-------|
| `VideoAspectRatio.useFullScreen` | `VideoFitMode.cover` | Now properly fills screen |
| `VideoAspectRatio.useAspectRatio` | `VideoFitMode.contain` | Same behavior |
| `VideoAspectRatio.none` | `VideoFitMode.none` | Same behavior |
| `videoVisibilityEnum` parameter | `fitMode` parameter | Renamed for clarity |
The old API will be removed in v1.0.0. Update your code to use the new `fitMode` parameter.
## Lifecycle Methods
```dart
// Defer first frame (prevents jank)
SplashVideo.initialize();
// Resume Flutter rendering
SplashVideo.resume();
// Resumes frame painting
SplashVideo(
source: AssetSource(Assets.splashVideo),
backgroundColor: Colors.black,
onVideoComplete: () => _videoComplete(),
videoConfig: const VideoConfig(
scale: VideoScaleMode.fill,
useSafeArea: true,
)
);
```
