loading<T> static method

Future<T?> loading<T>(BuildContext context, { String? message, Widget? indicator, bool useRootNavigator = true, XLook look = XLook.standard, })

Shows a non-dismissible loading dialog.

Close it with Navigator.of(context, rootNavigator: useRootNavigator) .pop() after the operation completes.
