‏AnimatedVisibility وCrossfade

Sometimes you want content to slide or fade in rather than pop. AnimatedVisibility animates a Composable as it enters and exits the screen. ✨

Give AnimatedVisibility a boolean and a content lambda. When the boolean flips, it animates that content in or out for you.

Out of the box it uses a gentle fade plus expand and shrink. The element appears and disappears smoothly without any extra configuration.

Set the enter parameter to choose how content arrives. Combine transitions like fadeIn and slideInVertically with the plus operator.

The exit parameter controls how content leaves. You can mirror the entrance or pick a different effect like shrinkOut for variety.

Compose ships many transitions: slideIn, expandHorizontally, scaleIn, and their exit pairs. Mix them to design exactly the motion you want.

To replace one Composable with another, reach for Crossfade. It fades the old content out while the new content fades in. 🔀

Give Crossfade a targetState. Whenever that value changes, it animates between the content produced for the old and new states.

Crossfade shines when switching between distinct views, like loading versus loaded states or two tabs, giving a polished blend instead of a jarring swap.

Pass an animationSpec to Crossfade to slow down or speed up the blend. A longer tween makes the transition feel softer and more deliberate.

Use AnimatedVisibility to show or hide one thing, and Crossfade to swap between alternatives. Each solves a different appearance problem.

Which Composable smoothly swaps one piece of content for another?

You now animate appearance with AnimatedVisibility and blend between views with Crossfade, customizing enter, exit, and timing. 🎉
