AboutListTileModifier class

A ListTile that shows an about box.

This widget is often added to an app's Drawer. When tapped it shows an about box dialog with showAboutDialog.

The about box will include a button that shows licenses for software used by the application. The licenses shown are those returned by the LicenseRegistry API, which can be used to add more licenses to the list.

If your application does not have a Drawer, you should provide an affordance to call showAboutDialog or (at least) showLicensePage.

{@tool dartpad} This sample shows two ways to open AboutDialog. The first one uses an AboutListTile, and the second uses the showAboutDialog function.
