camera_extended_android

Android implementation of camera_extended with native aspect ratio support.

Built with the CameraX library.

Features

This package extends the original camera_android_camerax with:

  • Native Aspect Ratio Selection - Configure aspect ratio at CameraX level
  • Native 1:1 Square Support - Uses native square formats (1088x1088, 720x720)
  • Automatic Fallback - Falls back to 4:3 when requested ratio not available

Aspect Ratio Support

Ratio Support Resolution Examples
16:9 Native 1920x1080, 1280x720
4:3 Native 1440x1080, 640x480

How It Works

The plugin uses CameraX's ResolutionSelector with AspectRatioStrategy:

// For 1:1, requests native square format
ResolutionSelector(
  resolutionStrategy: ResolutionStrategy(
    boundSize: Size(1088, 1088),
    fallbackRule: CLOSEST_HIGHER_THEN_LOWER
  ),
  aspectRatioStrategy: AspectRatioStrategy(
    preferredAspectRatio: RATIO_4_3, // fallback
    fallbackRule: AUTO
  )
)

<uses-permission android:name="android.permission.CAMERA" />
