In Flutter, it is a simple function that lets you show a pop-up or modal window on top of the current screen. The
Flutter showDialog is often used for things like alerts, confirmation messages, or custom pop-ups. You need to provide a context to use this function, and it usually returns a Dialog widget inside a builder function. You can make the pop-up fit your needs by adding buttons, text fields, and more. The dialog stops users from interacting with the app's main content until it's closed. To close it, you can use actions like Navigator.pop. It’s pretty easy to use and makes your app interactive and user-friendly.
