Build in layouts #

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

fit: BoxFit.fill,
);
},
itemCount: 10,
itemWidth: 300.0,

Very easy to create you own custom animation:

new Swiper(
layout: SwiperLayout.CUSTOM,
customLayoutOption: new CustomLayoutOption(
startIndex: -1,
stateCount: 3
).addRotate([
-45.0/180,
0.0,
45.0/180
]).addTranslate([
new Offset(-370.0, -40.0),
new Offset(0.0, 0.0),
new Offset(370.0, -40.0)
]),
itemWidth: 300.0,
itemHeight: 200.0,
itemBuilder: (context, index) {
return new Container(
color: Colors.grey,
child: new Center(
child: new Text("$index"),
),
);
},
itemCount: 10)

copied to clipboard
The CustomLayoutOption is designed to describe animations.
It is very easy to specify every state of items in Swiper.
new CustomLayoutOption(
startIndex: -1, /// Which index is the first item of array below
stateCount: 3 /// array length
).addRotate([ // rotation of every item
-45.0/180,
0.0,
45.0/180
]).addTranslate([ /// offset of every item
new Offset(-370.0, -40.0),
new Offset(0.0, 0.0),
new Offset(370.0, -40.0)
])
