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.

Implementation

static Future<MultipartFile> fromFile(
  String filePath, {
  String? filename,
  MediaType? contentType,
}) =>
    multipartFileFromPath(
      filePath,
      filename: filename,
      contentType: contentType,
    );
