Overview

We often use pop-ups in our apps to show messages or some basic UI. These pop-ups aren’t full pages but overlays that stack on the current page. However, navigating to and back from these overlays uses the same system.

There are three kinds of overlays in Flutter: snackbar, dialog, and bottom sheet. Let’s discuss each one.

Flutter requires us to use context to open up these overlays, but GetX removes that dependency. This means we are not restricted to opening the overlays from the view; we can open them from anywhere in the code.

Snackbar

Snackbars are tiny message overlays that appear for a set duration and are typically used to give the user feedback about an action or error.
