ZdsNetworkAvatar class

A circular container used to display a user's profile picture fetched from the internet.

This widget will prioritize showing the image fetched from url. If an image can't be loaded, the avatar will show a circle with a plain background using backgroundColor and the user's initials.

The image fetched from url is not loaded again every time, but is rather cached to reduce network usage.

See also:

  • ZdsAvatar, an avatar used to display an image that is stored locally, or just the initials.
  • CachedNetworkImage, which this avatar uses to not have to download the image every time.
