How do you sort a list by bool in Dart

问题

How do you sort a List in dart based on a bool value, the compareTo method doesn't work with bool. I want true values to appear at the top of the list.

回答1:

You can define you own compare function for bool and pass it to the sort method of List.

Example with booleans as your bool List:

booleans.sort((a, b) {
  if(b) {
    return 1;
  }
  return -1;
});

This example tells the sort method that true elements should be sorted higher than false elements.
