<itemvalue="The `wasSynchronouslyLoaded` argument specifies whether the image was available synchronously (on the same [rendering pipeline frame](renderingRendererBindingdrawFrame.html) as the `Image` widget itself was created) and thus able to be painted immediately. If this is false, then there was one or more rendering pipeline frames where the image wasn't yet available to be painted. For multi-frame images (such as animated GIFs), the value of this argument will be the same for all image frames. In other words, if the first image frame was available immediately, then this argument will be true for all image frames."/>
<itemvalue="The `child` argument contains the default image widget and is guaranteed to be non-null. Typically, this builder will wrap the `child` widget in some way and return the wrapped widget. If this builder returns `child` directly, it will yield the same result as if [Image.frameBuilder] was null. The `frame` argument specifies the index of the current image frame being rendered. It will be null before the first image frame is ready, and zero for the first image frame. For single-frame images, it will never be greater than zero. For multi-frame images (such as animated GIFs), it will increase by one every time a new image frame is shown (including when the image animates in a loop)."/>

<itemvalue="Gestures from a trackpad. A trackpad here is defined as a touch-based pointer device with an indirect surface (the user operates the screen by touching something that is not the screen). When the user makes zoom, pan, scroll or rotate gestures with a physical trackpad, supporting platforms dispatch events with kind [trackpad]. Events with kind [trackpad] can only have a [PointerChange] of `add`, `remove`, and pan-zoom related values. Some platforms don't support (or don't fully support) trackpad gestures, and might convert trackpad gestures into fake pointer events that simulate dragging. These events typically have kind [touch] or [mouse] instead of [trackpad]. This includes (but is not limited to) Web, and iOS when `UIApplicationSupportsIndirectInputEvents` isn't present in `Info.plist` or returns NO. Moving the pointing cursor or clicking with a trackpad typically triggers [touch] or [mouse] events, but never triggers [trackpad] events."/>
