install method

  1. @override
Future<void> install(
  1. ModelSource source
)
override

Installs the model from the given source

This method performs the actual installation:

  • NetworkSource: downloads from URL
  • AssetSource: copies from Flutter assets
  • BundledSource: accesses native resources
  • FileSource: registers external file path

Throws:

  • UnsupportedError if this handler doesn't support the source type
  • ArgumentError if the source is invalid
  • Platform-specific exceptions for download/file errors

Implementation

@override
Future<void> install(ModelSource source) async {
  if (source is! BundledSource) {
    throw ArgumentError('BundledSourceHandler only supports BundledSource');
  }

  // Get platform-specific bundled resource path
  // This path is used directly by the native layer (no copying needed)
  final bundledPath = await fileSystem.getBundledResourcePath(source.resourceName);

  // Get file size for metadata
  final sizeBytes = await fileSystem.getFileSize(bundledPath);

  // Save metadata to repository
  final modelInfo = ModelInfo(
    id: source.resourceName,
    source: source,
    installedAt: DateTime.now(),
    sizeBytes: sizeBytes,
    type: ModelType.inference,
    hasLoraWeights: false,
  );

  await repository.saveModel(modelInfo);
}
