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 image provider key, so toggling it at runtime resolves a different image stream. The widget paints nothing while that stream resolves, and which frame it starts on depends on whether its key is still held by the ImageCache. Wrap the widget in a TickerMode instead to pause and resume an animation in place.
Implementation
final bool animate;
