toast function

ScaffoldFeatureController<Widget, dynamic> toast({ required BuildContext context, String? title, required String message, Icon? icon, Duration duration = const Duration(seconds: 8), dynamic onTap(Function)?, bool? error, bool hideCloseButton = false, Color? backgroundColor, Color? foregroundColor, double runSpacing = 12, })

Display a snackbar

When the body of the snackbar is tapped, onTap will be called with a callback that will hide the snackbar.

Call the function parameter passed on the callback to close the snackbar.

toast( title: 'title',  message: 'message', onTap: (close) => close());
toast(  title: 'error title', message: 'error message',  error: true );
