Flutter – how can I check the one element in list has repeated three times In dart?

I have the list of elements in flutter like this in dart:

[3, 1, 0, 1, 3, 1]

I want to this:
if ‘1’ element of this list is repeated three times then do something.
as you see ‘1’ number has been repeated three times.

    Try this

    void main() {
  List<int> myList = [3, 1, 0, 1, 3, 1];

  // Count the occurrences of '1' in the list
  int countOfOnes = myList.where((element) => element == 1).length;

  // Check if '1' is repeated three times
  if (countOfOnes == 3) {
    // Do something
    print("The element '1' is repeated three times.");
  } else {
    // Do something else
    print("The element '1' is not repeated three times.");
  }
}

  int count = 0;

  for (int number in numbers) {
    if (number == 1) {
      count++;
      if (count == 3) {
        print("The number '1' is repeated three times.");
        break;
