Swiper/Carousel for flutter, with multiple layouts, infinite loop. Compatible with Android & iOS.
We are using this project flutter_page_indicator now .
Finally, we have PageTransformer like android, just set a transformer to Swiper,
it returns a widget that has been transformed. For now, only support for layout DEFAULT.
Thanks to @FlutterRocks ,you've done great job 👏.
We are using this project transformer_page_view now .

Very easy to create you own custom animation:
Swiper(
layout: SwiperLayout.CUSTOM,
customLayoutOption: CustomLayoutOption(
startIndex: -1,
stateCount: 3
)..addRotate([
-45.0/180,
0.0,
45.0/180
])..addTranslate([
Offset(-370.0, -40.0),
Offset(0.0, 0.0),
Offset(370.0, -40.0)
]),
itemWidth: 300.0,
itemHeight: 200.0,
itemBuilder: (context, index) {
return Container(
color: Colors.grey,
child: Center(
child: Text("$index"),
),
);
},
itemCount: 10,
)
The CustomLayoutOption is designed to describe animations.
It is very easy to specify every state of items in Swiper.
CustomLayoutOption(
// Which index is the first item of array below
startIndex: -1,
// array length
stateCount: 3
)..addRotate([
// rotation of every item
-45.0/180,
0.0,
45.0/180
])..addTranslate([
// offset of every item
Offset(-370.0, -40.0),
Offset(0.0, 0.0),
Offset(370.0, -40.0)
]);
ConstrainedBox(
child: Swiper(
outer:false,
itemBuilder: (c, i) {
return Wrap(
runSpacing: 6.0,

return SizedBox(
