updateUserAvatar method

Future<MyUserEventsVersionedMixin?> updateUserAvatar(
  1. MultipartFile? file,
  2. CropAreaInput? crop, {
  3. void onSendProgress(
    1. int count,
    2. int total
    )?,
})

Updates or resets the MyUser.avatar field with the provided image file.

HTTP request for this mutation must be Content-Type: multipart/form-data containing the uploaded file and the file argument itself must be null, otherwise this mutation will fail.

Authentication

Mandatory.

Result

One of the following MyUserEvents may be produced on success:

Idempotent

Succeeds as no-op (and returns no MyUserEvent) if the authenticated MyUser uses the specified image file already as his avatar with the same crop area.
