copyAssetToFile method
Copies asset file directly to target path using LargeFileHandler This is the CORRECT way to handle large files
Implementation
Future<void> copyAssetToFile(String assetPath, String targetPath) {
// Do NOT wrap exceptions: callers (e.g. AssetSourceHandler) match by type
// — wrapping MissingPluginException in a generic Exception would defeat
// the desktop fallback path (#250).
return _handler.copyAssetToLocalStorage(
assetName: assetPath,
targetPath: targetPath,
);
}
