Create alert dialogs, custom dialogs, and full-screen dialogs in Flutter for a better user experience in your mobile applications.

You can see dialog on nearly every mobile application out there. Most applications use dialog to give an alert or facilitate intermediate action that is an alternative from the main flow of the application.

As an example, let’s say there is a submit button, and when the user presses submit, it shows a dialog to indicate the action is complete and to include instructions on the next steps. That is an intermediate action from the main flow.

Because dialogs are essential to mobile applications, Flutter facilitates alert and full-screen dialogs and also gives you the option to create custom dialogs. We’ll be covering these aspects of dialogs in Flutter:

• Creating an alert dialog in Flutter
• Applying action buttons to a dialog
• Closing and dismissing dialog
• Creating a custom dialog
• Creating a full-screen dialog
