animate property
Whether multi-frame images, such as GIFs, play automatically.
When false only the first frame is shown and the image is frozen there. Defaults to true.
This is part of the provider key, so toggling it at runtime resolves a different image stream. Which frame that stream starts on depends on whether its key is still held by the ImageCache: an animation that played before is likely to resume where it left off rather than restart. Use TickerMode instead to pause and resume in place without changing the key.
Implementation
final bool animate;
