showWidgetDialog<T> static method

Future<T?> showWidgetDialog<T>(BuildContext context, Widget content, { String? title, List<Widget>? actions, DialogActions defaultActions = DialogActions.ok, String? okActionText, String? cancelActionText, })

Shows a dialog with the given content.

Set the title to display the title on top Specify custom actions to provide dialog specific actions, alternatively specify the defaultActions.
