How do I create a "fake" dart:io File from in-memory bytes?

Question

I have the in-memory bytes of a "blob", but the API that I want to process this "blob" with only accepts dart:io File objects.

Is there a way to create a "fake" dart:io File , simply wrapping my in-memory bytes, so that I can pass this "fake" File to my API?

Assume that a file system doesn't exist, and assume that I can't write the in-memory bytes to a "real" file.

Thanks!

You can create a memory-file using MemoryFileSystem from the package file:

Example:

File file = MemoryFileSystem().file('test.dart')
  ..writeAsBytesSync(blobBytes);
