concat4 method

Iterable<T> concat4(Iterable<T> c1, Iterable<T> c2, Iterable<T> c3, Iterable<T> c4,)

Concatenates this iterable and four another iterables.

Appends the values of four given Iterables to the end of this iterable, resulting in an iterable that is the concatenation of all of them.

Example:

void main() {
  final list = [0, 1];
  final result = list.concat4(
    [2, 3],
    [4, 5],
    [6, 7],
    [8, 9],
  );

  // Result: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
}

Implementation

Iterable<T> concat4(
  Iterable<T> c1,
  Iterable<T> c2,
  Iterable<T> c3,
  Iterable<T> c4,
) {
  return followedBy(c1).followedBy(c2).followedBy(c3).followedBy(c4);
}
