Flutter app for LG WebOS TV

We are trying to run the flutter Web app as WebOS basic app. It works well in WebOS Simulator. But in real TV, We are getting Fetch API cannot load the FontManifest.json file. URL scheme ‘file’ is not supported error. PFA error screenshot for reference.

Need your support to resolve this issue.

Note: Hosted Web OS app works file with flutter web. But we are trying WebOS Basic app as it eliminates delay in loading the page.

Please share if you have any documentation for the same.
