CloseButton class
A material design close button.
A CloseButton is an IconButton with a "close" icon. When pressed, the close button calls Navigator.maybePop to return to the previous route.
Use a CloseButton instead of a BackButton on fullscreen dialogs or pages that may solicit additional actions to close.
See also:
- AppBar, which automatically uses a CloseButton in its AppBar.leading slot when appropriate.
- BackButton, which is more appropriate for middle nodes in the navigation tree or where pages can be popped instantaneously with no user data consequence.
- IconButton, to create other material design icon buttons.
