WebAssetSourceHandler class
Handles installation of models from Flutter assets on web platform
On web, Flutter assets are served by the web server at paths like:
- assets/models/gemma.task
- assets/lora/weights.bin
This handler:
- Registers the asset URL with WebFileSystemService
- Saves metadata to ModelRepository
- MediaPipe loads directly from the URL (no file copy)
Features:
- No file copying (web has no local file system)
- Direct URL registration for MediaPipe
- Simulated progress for UX consistency
- Instant "installation" (assets already bundled)
Platform: Web only
