File is not support on web, you should make some Platform Code Separation like

https://github.com/fluttercandies/extended_image_library/blob/33422e7f5fbc755c6ec63cf0741cabd0f71cd2cf/lib/src/platform.dart#L11

[piperun]

Thanks for the response!
I realized that too after some searching around, however when I was querying folks on the Flutter discord they pointed out:
"They don't provide a public common interface for cross-file, yet they don't use XFile from the cross_file package", which is what the issue was intended to be about.

[zmtzawqlp]

ExtendedImage.file corresponds to Image.file , this package will not to be changed before Image.file use XFile

[piperun]

Ah that's fair, then I assume I shouldn't worry about extend_image's own File class?

[zmtzawqlp]

Perhaps I can implement the [File Class] (https://github.com/fluttercandies/extended_image_library/blob/33422e7f5fbc755c6ec63cf0741cabd0f71cd2cf/lib/src/_platform_web.dart#L7) based on cross_file.

[zmtzawqlp]

it has no plan for now
