AboutDialog class
An about box. This is a dialog box with the application's icon, name, version number, and copyright, plus a button to show licenses for software used by the application.
To show an AboutDialog, use showAboutDialog.
If the application has a Drawer, the AboutListTile widget can make the process of showing an about dialog simpler.
The AboutDialog shown by showAboutDialog includes a button that calls showLicensePage.
The licenses shown on the LicensePage are those returned by the LicenseRegistry API, which can be used to add more licenses to the list.
