For ascending

var dataList = [1, 6, 8, 2, 16, 0] //your dynamic list
dataList.sort((a, b) => a.compareTo(b));

For descending

var dataList  = [1, 6, 8, 2, 16, 0] //your dynamic list
dataList .sort((b, a) => a.compareTo(b));

don't forgot to call setState to reload your UI again

Thank you Harizh, I believe this is the easiest way, it 'is collecting the result in a separate list then sort it then return it back to widget.
