SlideWidget class abstract

An abstract class helpful to create a Slide to be use in PresentationWidget.

A slide can be created by extending this class and by overriding the methods slide (foreground of the slide) and background (background of the slide)

It uses a Stack to place the foreground and background widgets.

It also takes in a controller where we pass a SlideController to handle custom methods of the advancement and reversal of the slide. Take a look at SlideController for more information.

The below example shows how to create a slide using SlideWidget

class CustomSlide extends SlideWidget {
  const CustomSlide({super.key});

  @override
  Widget slide(BuildContext context) => ForegroundWidget();

  @override
  Widget background() => BackgroundWidget();
}

  • TitleSlide, a template slide that takes title and subtitle as input.
  • SectionHeader, a template slide that takes in just title as input.
  • BlankSlide, a template slide that is blank without any foreground.
  • CaptionSlide, a template slide that is used for captions.
