Hi,
I am using your plugin, I have a list of 20 items, when I scroll to the last page it does not go to the first one as expected, it gives a red screen with this error.
RangeError (index): Invalid value: Not in inclusive range 0..19: 20
and here is the configuration of the PageTransformer
TransformerPageView(
key: _key,
scrollDirection: Axis.horizontal,
pageSnapping: true,
loop: true,
physics: BouncingScrollPhysics(),
pageController: _pageController,
transformer: AccordionTransformer(),
onPageChanged: _onPageChanged,
itemCount: questionList.length,
itemBuilder: (context, i) {
}

When I tried to comment the pageController it works fine, but I need the controller to pass it to indicators class so when I click on the indicator it will animateTo page.
