Flutter image automatic slideshow/carousel with random intervals given












1















I seen there is an image carousel package for flutter.



Widget Carousel = new Container(
child: new Carousel(
children: [
new AssetImage('images/img1.jpg'),
new AssetImage('images/img2.jpg'),
new AssetImage('images/img3.jpg'),
].map((bgImg) => new Image(image: bgImg, width: 1500.0, height: 1500.0, fit: BoxFit.cover)).toList(),
displayDuration: const Duration(seconds: 1),
),


);



I wanted to know if there is any chance to make this automatic and with random intervals given in an array.



Thank you.



Tried this - is this not consuming too much?



Widget build(BuildContext context) {

SystemChrome.setEnabledSystemUIOverlays();

setNewImage() {
List<int> duration = [5, 7, 3, 10];
List<String> imageURLs = ["assets/logo.jpg", "assets/logo.png", "assets/side-logo.png", "assets/background.jpg"];

(i == 4) ? i = 0 : i = i;

int waitTime = duration[i];
print("wait time: " + waitTime.toString() + " i: " + i.toString());

Future.delayed(Duration(seconds: waitTime), () {

setState(() {
i++;
int nextImg = (i+1 == 5) ? 0 : i;
print("Setting: " + nextImg.toString());
currentMainImage = imageURLs[nextImg];
});
});
}

setNewImageFunction() async {
await setNewImage();
}

setNewImageFunction();

}


ignore the if statements and the list building... just to image change itself.
