WebFileSourceHandler class
Handles installation of models from external file paths (WEB PLATFORM)
On web, FileSource can ONLY work with:
- HTTP/HTTPS URLs (e.g., https://example.com/model.task)
- Asset paths (e.g., assets/models/model.task)
Local file paths (e.g., /path/to/model.task) are NOT supported because web browsers cannot access the local file system.
This handler:
- Validates that the path is a URL or asset path
- Registers the URL with WebFileSystemService
- Saves metadata to ModelRepository
- MediaPipe loads directly from the URL
Features:
- URL validation (must be http://, https://, or assets/)
- Direct URL registration (no copying)
- Single-step progress (URL already exists)
- Clear error messages for unsupported paths
Platform: Web only
