Compose Columns Permit For Free

You can read about layouts in Jetpack Compose here. The main difference between the Row and LazyRow functions is that the LazyRow creates a horizontally scrollable list of content. The LazyRow and LazyColumn allow us to use the following functions to add content to it: item adds an item.

Lazy layouts are a set of UI components that enable you to show huge datasets in your app in an effective manner. Only the objects that are visible on the screen are loaded and rendered for these components, which optimizes performance by using less memory.

LazyColumn produces a vertically scrolling list, and LazyRow produces a horizontally scrolling list. The Lazy components are different to most layouts in Compose. Instead of accepting a @Composable content block parameter, allowing apps to directly emit composables, the Lazy components provide a LazyListScope.() block.

We can make the Column scrollable by using the verticalScroll() modifier. See the Gestures documentation for more information.

Surface is used when you want a surface for your UI , you can set the background color, shape etc. Card on the other hand, have default elevation(Material Design Standard) and pretty much have every property as the surface .

The critical difference between Column and LazyColumn lies in their rendering mechanism. Rendering: While Column will render all its children regardless of whether they're visible on the screen or not, LazyColumn only renders items that the user can currently see.

Use Column to place items vertically on the screen. Similarly, use Row to place items horizontally on the screen. Both Column and Row support configuring the alignment of the elements they contain. Use Box to put elements on top of another.

A LazyColumn is a vertically scrolling list that only composes and lays out the currently visible items. It's similar to a Recyclerview in the classic Android View system.
