01 - AboutDialog |
#shorts #flutter #aboutdialog #widgets
About Dialog is a wrapper over Dialog. You can use it to show About page of the application.
Invoke `showAboutDialog` to show the dialog . By default this Dialog shows a title, and 2 buttons. The title of the dialog is fetched from `title` that you have given to the `MaterialApp`.
Tapping the View licenses button will navigate to a Licenses page. This page is called as LicensePage in Flutter SDK. LicensePage contains the dependencies that the app depends on. You can go inside each of these dependencies as well and see their licenses.
Tapping the Close button will close the dialog.
You can also customise the UI of this dialog. A typical About Dialog will have
1. application name - this will override the MaterialApp title.
2. application icon - shown towards left of title
3. a legalese - short description of legal
4. application version
You can also add children to this dialog, that will be shown between these two buttons and short description.
