int _current = 0;
@override
Widget build(BuildContext context) {
return Stack(
children: [
CarouselSlider(
items: child,
autoPlay: true,
aspectRatio: 2.0,
onPageChangedCallback: (index) {
setState(() {
_current = index;
});
},
),
Positioned(
top: 0.0,
left: 0.0,
right: 0.0,
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: map<Widget>(imgList, (index, url) {
return Container(
width: 8.0,
height: 8.0,
margin: EdgeInsets.symmetric(vertical: 10.0, horizontal: 2.0),
decoration: BoxDecoration(
shape: BoxShape.circle,
color: _current == index ? Color.fromRGBO(0, 0, 0, 0.9) : Color.fromRGBO(0, 0, 0, 0.4)
),

}),

)
]
);
}
}
Yes.
Use the pauseAutoPlayOnTouch which takes a duration and when set, enables touch detection.
Touch Detection is only active if the autoPlay property is set to true.
If the screen is touched it will pause the automatic playback for the set duration.
if touched again during the time out the timer is reset to the duration passed to pauseAutoPlayOnTouch.
This feature can be useful if you want users to be able to interact with the screen and not have the pages continue sliding, forcing the user to repeatedly swipe back. One such example could be a commercial advertisement where the customers can react to something they like.
Yes. This was added by popular demand in patch 1.2.0.
Just set the constructor argument enableInfiniteScroll to false.
The example folder contains an example showcasing all features.
