Implementing ScalingLazyColumn to showcase your content

ScalingLazyColumn extends LazyColumn, which is very powerful in Jetpack Compose. You can think of ScalingLazyColumn as a component in Wear OS that is used to display a list of items that can be scrolled vertically. The items are scaled and positioned based on their position in the list, and the entire list can be scrolled by dragging the top or bottom of the list.

You can use it, for example, to display a list of components; in our example, we will use it to display all the elements we created in previous recipes. You will also notice we used it in the Implementing a scrollable list recipe, where we have a list and displayed the items.

Getting ready

You will need to have completed the previous recipes to continue with this recipe. In addition, in this recipe, instead of commenting on all the elements we created, we will display them as items in ScalingLazyColumn.
