Research direction
Start by reproducing GFItemsCarousel with rowCount set to 5 and three children, then inspect the GFItemsCarousel implementation and its drag or scrolling behavior. Done means dragging this configuration no longer causes rapid flashing or leaves the carousel with an incorrect offset, while the expected scrolling behavior is preserved.

Description
Describe the bug
Currently there is a bug if the row count is bigger than the children itself. The ui is fine but when you start to drag, the ui will flashing faster (it's going left and right very fast) and the it eventually will stop and it will make the offset very weird.
To Reproduce
Steps to reproduce the behavior:
final List<String> imageList = [
"https://cdn.pixabay.com/photo/2017/12/03/18/04/christmas-balls-2995437_960_720.jpg",
"https://cdn.pixabay.com/photo/2017/12/13/00/23/christmas-3015776_960_720.jpg",
"https://cdn.pixabay.com/photo/2019/12/19/10/55/christmas-market-4705877_960_720.jpg",
];
GFItemsCarousel(
rowCount: 5,
children: imageList.map(
(url) {
return Container(
margin: EdgeInsets.all(5.0),
child: ClipRRect(
borderRadius: BorderRadius.all(Radius.circular(5.0)),
child:
Image.network(url, fit: BoxFit.cover, width: 1000.0),
),
);
},
).toList(),
),
- As per code block above, the row must be higher than the number of children
- Based on the screenshot above, the green color box will be initial display. When the user scroll or drag the carousel, the red color box highlighted the bug happened
Expected behavior
Is either disabling the animation or physic scrolling.
