Similar to PageView, StoryPageView uses StoryPageController to control its behaviour. StoryPageController is a special type of PageController that used by PageView, which supports all features from PageController.

),

StoryPageView(
indicatorPosition: StoryPageIndicatorPosition.custom(
layoutBuilder: (c, pageView, indicator) => SafeArea(
child: Column(
children: [
Padding(
padding: const EdgeInsets.symmetric(vertical: 8, horizontal: 12),
child: indicator, // Page Indicator
