  print(strArr);  
  
}

Example 2: inserting elements to integer array dart

void main() {
  
  List<int> intArr = [1,2,3,4,5];
  
  //adding single int to list
  intArr.add(6);
  
  //adding multiple int to list
  intArr.addAll([7,8]);
  
  //adding element or elements to specific location
  //syntax: List.insert(index,value)
  intArr.insert(0,0);
  
  //syntax: List.insertAll(index, iterable_list_of _values)
  intArr.insertAll(0,[-2,-1]);
