  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
    body: Swiper(
        itemBuilder: (BuildContext context,int index){
          return Image.network("https://via.placeholder.com/350x150",fit: BoxFit.fill,);

onTap	void onTap(int index)	Called when user tap ui.
duration	300.0	The milliscends of every transaction animation costs
pagination	null	set SwiperPagination() to show default pagination
control	null	set SwiperControl() to show default control buttons

Pagination

Build in layouts

Swiper(
  itemBuilder: (BuildContext context, int index) {
    return Image.network(
      "https://via.placeholder.com/288x188",
      fit: BoxFit.fill,
    );
  },
  itemCount: 10,
  viewportFraction: 0.8,
  scale: 0.9,
)

Swiper(
  itemBuilder: (BuildContext context, int index) {
    return Image.network(
      "https://via.placeholder.com/288x188",
      fit: BoxFit.fill,
    );
  },
  itemCount: 10,
  itemWidth: 300.0,
  layout: SwiperLayout.STACK,
)

Swiper(
    itemBuilder: (BuildContext context, int index) {
      return Image.network(
        "https://via.placeholder.com/288x188",
        fit: BoxFit.fill,
      );
    },
    itemCount: 10,
    itemWidth: 300.0,
    itemHeight: 400.0,
    layout: SwiperLayout.TINDER,
 )

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)
]);

                ),

              ],
