/// Defaults to 1 second. This can be used as a place holder for cached images. By
/// delaying for several milliseconds it can reduce the occurrences of placeholders
/// flashing on screen as the cached image is loaded. Images that take longer to fetch
/// or process from the cache will result in a [PlatformProgressIndicator] indicator
/// being displayed.
