As a part of this effort, the following API changes were made in addition to internal changes <ul> <li>Added a new Indication API, <code translate="no" dir="ltr">IndicationNodeFactory</code>. This leads to more performant Indication implementations compared to the previous (now deprecated) <code translate="no" dir="ltr">rememberUpdatedInstance</code> API. For migration information, see <a href="http://developer.android.com/">developer.android.com</a>.</li> <li><code translate="no" dir="ltr">clickable</code> / <code translate="no" dir="ltr">combinedClickable</code> / <code translate="no" dir="ltr">selectable</code> / <code translate="no" dir="ltr">toggleable</code> now accepts a nullable <code translate="no" dir="ltr">MutableInteractionSource</code> parameter. If null, and the provided Indication is an <code translate="no" dir="ltr">IndicationNodeFactory</code>, the Indication can be lazily created only when needed, which improves performance. If you are not hoisting and using the <code translate="no" dir="ltr">MutableInteractionSource</code>, it is recommended to pass null instead of passing <code translate="no" dir="ltr">remember { MutableInteractionSource() }</code>.</li> <li><code translate="no" dir="ltr">Indication#rememberUpdatedInstance</code> has been deprecated.

We are excited to announce enhancements to the experimental <code translate="no" dir="ltr">FlowRow</code> and <code translate="no" dir="ltr">FlowColumn</code>, now featuring <code translate="no" dir="ltr">maxLines</code> and overflow support, alongside the debut of <code translate="no" dir="ltr">ContextualFlowRow</code> and <code translate="no" dir="ltr">ContextualFlowColumn</code>. This update is designed to provide performance optimal components, where <code translate="no" dir="ltr">ContextualFlow*</code> is perfect for a large number of items making use of a small maxLines config and dynamic +N see more buttons, and <code translate="no" dir="ltr">FlowRow</code> and <code translate="no" dir="ltr">FlowColumn</code> is perfect for a small number of items, less than 100 items.

This was done in order to get behavior to scale up the underlying Painter if the layout size is larger than the intrinsic size of the painter while maintaining the aspect ratio. This behavior better matches expectations for providing fixed sizes to the Image while not affecting the default behavior if only the intrinsic size is used to compute the size of the composable.
