ComparableWrapper<T> class

Wraps a value in a Comparable interface with a specified comparison function.

For example, this can be used to combine SortWithKeyExtension.sortWithKey and compareIterables:

class Name {
  String surname;
  String givenName;

  Name(this.surname, this.givenName);
}

void main() {
  var names = [
    Name('Smith', 'Jane'),
    Name('Doe', 'John'),
    Name('Doe', 'Jane'),
    Name('Galt', 'John'),
  ];

  names.sortWithKey(
    (name) => ComparableWrapper(
      [name.surname, name.givenName],
      compareIterables,
    ),
  );
}
