Build in layouts
Swiper(
itemBuilder: (context, index) {
return Image.network(
"https://via.placeholder.com/288x188",
fit: BoxFit.fill,
);
},
itemCount: 10,
viewportFraction: 0.8,
scale: 0.9,
)
Swiper(
itemBuilder: (context, index) {
return Image.network(
"https://via.placeholder.com/288x188",
fit: BoxFit.fill,
);
},
itemCount: 10,
itemWidth: 300.0,
layout: SwiperLayout.STACK,
)
Swiper(
itemBuilder: (context, 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([
const Offset(-370.0, -40.0),
const Offset(0.0, 0.0),
const 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(
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
const Offset(-370.0, -40.0),
const Offset(0.0, 0.0),
const Offset(370.0, -40.0)
])
Codes
ConstrainedBox(
constraints: BoxConstraints.loose(Size(screenWidth, 170.0))
child: Swiper(

itemBuilder: (c, i) {
return Wrap(
runSpacing: 6.0,
