Jetpack Compose Snackbar in Material 3 Compose

<a href="https://m3.material.io/components/snackbar/overview" class="external" target="_blank">Material Design snackbar</a>.

Snackbars provide brief messages about app processes at the bottom of the screen.

Snackbars inform users of a process that an app has performed or will perform. They appear temporarily, towards the bottom of the screen. They shouldn’t interrupt the user experience, and they don’t require user input to disappear.

A Snackbar can contain a single action. "Dismiss" or "cancel" actions are optional.

Snackbars with an action should not timeout or self-dismiss until the user performs another action. Here, moving the keyboard focus indicator to navigate through interactive elements in a page is not considered an action.

This component provides only the visuals of the Snackbar. If you need to show a Snackbar with defaults on the screen, use SnackbarHostState.showSnackbar:
