Last element and last 10 element:

List<int> listNumber = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19];
int lastNumber = listNumber.last;

List<int> last10Number = [];
if(listNumber.length > 10){
  for(int i=listNumber.length - 10; i < listNumber.length; i++){
    last10Number.add(listNumber[i]);
  }
}

print("$lastNumber\n");
last10Number.forEach((element)=> print(element));

    **//Dart Code: Find 1st, Last, 2nd last and 3rd last value in Array**

void main() {

  List l1 = [1, 8, 5, 3, 0, 6, 7, 2, 9, 4,];
  
  print('Our original Array: $l1');

  // Sorting an array

  l1.sort();
  
  print('After sorting and Array: $l1');
  
  //Now we find the first, last, 2nd and 3rd last values of array
  
  var first = l1.first;

  print('Last value of Array: $first');
  
  var last = l1.last;

  print('Last value of Array: $last');
  
  var last2 =l1[l1.length-2];

  print('Last value of Array: $last2');
  
  var last3 =l1[l1.length-3];

  print('Last value of Array: $last3');
  
}

you can use last property for read/write, inherited-getter:

last is a returns the last element from the given list.

var lst = ["element1" , "element2" , "element3"];
lst.last // -> element3

or

lst[lst.length-1] //-> element3
