Segmenter - Conditional Export Router

This file uses Dart's conditional imports to automatically select the correct platform-specific implementation at compile time.

How It Works

export 'segmenter_stub.dart'          // Default (fallback)
    if (dart.library.io) 'segmenter_mobile.dart';  // Android/iOS

The compiler picks the RIGHT implementation based on the target platform. No runtime checks needed - it's resolved at build time.

Adding Web Support (Future)

When TensorFlow.js support is added:

export 'segmenter_stub.dart'
    if (dart.library.html) 'segmenter_web.dart'    // Web
    if (dart.library.io) 'segmenter_mobile.dart';  // Mobile

Usage

import 'package:mediasfu_sdk/components/background_components/segmenter/segmenter.dart';

final segmenter = createSegmenter();
await segmenter.initialize();

Classes

BackgroundSegmenterBase: Abstract base class for background segmenters.
SegmenterConfig: Configuration options for the segmenter.
SegmenterInputMetadata: Metadata for input images.
StubSegmenter: Stub implementation that returns frames unprocessed.

Enums

SegmenterInputFormat: Input image format for the segmenter.

Functions

createSegmenter() → BackgroundSegmenterBase: Factory function - returns StubSegmenter.

Typedefs

SegmenterFactory = BackgroundSegmenterBase Function(): Factory function type for creating segmenters.
