dialog<T> method

Future<T?> dialog<T>(Widget widget, { bool barrierDismissible = true, Color? barrierColor, bool useSafeArea = true, GlobalKey<NavigatorState>? navigatorKey, Object? arguments, Duration? transitionDuration, Curve? transitionCurve, String? name, RouteSettings? routeSettings, })

Show a dialog. You can pass a transitionDuration and/or transitionCurve, overriding the defaults when the dialog shows up and closes. When the dialog closes, uses those animations in reverse.
