initialize method

@override Future<void> initialize([ SegmenterConfig config = const SegmenterConfig() ])

Initialize the segmenter with optional configuration.

This may download models, allocate GPU resources, etc. Returns a Future that completes when ready.

Implementation

@override
Future<void> initialize([
  SegmenterConfig config = const SegmenterConfig(),
]) async {
  _config = config;

  // On iOS, macOS, and Windows, initialize native segmentation for preview
  if (_supportsNativeSegmentation) {
    try {
      final result = await _channel.invokeMethod<Map>('initialize', {
        'useGpu': true,
      });
      _nativeInitialized = result?['success'] as bool? ?? false;

      // Log initialization result with model status
      final modelLoaded = result?['modelLoaded'] as bool? ?? false;
      final engine = result?['engine'] as String? ?? 'unknown';
      final message = result?['message'] as String? ?? '';
      debugPrint(
          'MobileSegmenter: Native init result - success=$_nativeInitialized, modelLoaded=$modelLoaded, engine=$engine, message=$message');
    } catch (e) {
      debugPrint('MobileSegmenter: Native init failed - $e');
      _nativeInitialized = false;
    }
  }

  _isReady = true;
}
