Basic usage :
ImageView360(
key: UniqueKey(),
imageList: imageList,
),
copied to clipboard
Note: For ImageView360 to show instant changes on hot reload, you need to provide UniqueKey() so that the widget rebuilds every time.
Customisable usage :
ImageView360(
key: UniqueKey(),
imageList: imageList,
autoRotate: true, //Optional
rotationCount: 2, //Optional
rotationDirection: RotationDirection.anticlockwise, //Optional
frameChangeDuration: Duration(milliseconds: 50), //Optional
swipeSensitivity: 2, //Optional
allowSwipeToRotate: true, //Optional
onImageIndexChanged: (currentImageIndex) { //Optional
print("currentImageIndex: $currentImageIndex");
},
)

Note: For better experience always precache image before providing the images to the widget as follows.
Example for loading and precaching images from assets :
List<ImageProvider> imageList = List<ImageProvider>();
for (int i = 1; i <= 52; i++) {
imageList.add(AssetImage('assets/sample/$i.png'));
// To precache images so that when required they are loaded faster.
await precacheImage(AssetImage('assets/sample/$i.png'), context);
}
