A graphical icon widget drawn with a glyph from a font described in an IconData such as material's predefined IconDatas in Icons.

Icons are not interactive. For an interactive icon, consider material's IconButton.

There must be an ambient Directionality widget when using Icon. Typically this is introduced automatically by the WidgetsApp or MaterialApp.
