list.length

Example

In this example, we take a list of integers and find the length of this list programmatically using List.length property.

main.dart

void main() {
  var list = [2, 4, 8, 16, 32];
  var len = list.length;
  print('Length of given list : $len');
}

Output

Length of given list : 5
