fromFile method Null safety

Future<MultipartFile> fromFile(
  1. String filePath,
  2. {String? filename,
  3. MediaType? contentType}

Creates a new MultipartFile from a path to a file on disk.

filename defaults to the basename of filePath. contentType currently defaults to application/octet-stream, but in the future may be inferred from filename.

Throws an UnsupportedError if dart:io isn't supported in this environment.
