Snackbar is a brief message that appears at the bottom of the screen to provide feedback to a user. They contain non-critical information, typically indicating the status of an operation - such as the successful completion of a task, or the arrival of new data.

Snackbars are usually transient and disappear automatically after a few seconds, but may also offer a manual dismiss option or an action button. They are non-intrusive and allow users to continue their work undisturbed. Snackbar component plays a vital role in communication and the improvement of overall user experience by providing timely and context-appropriate feedback.
