padEnd method

Iterable<T> padEnd(
  1. int length, {
  2. required T padding,
})

Pads the iterable to be at least length, adding padding to the end as needed to guarantee the length.

If the iterable is already has at least length elements, the iterable is unchanged.

Implementation

Iterable<T> padEnd(int length, {required T padding}) sync* {
  if (length < 0) {
    throw ArgumentError.value(
      length,
      'length',
      'The value for "length" cannot be less than zero.',
    );
  }

  if (length == 0) {
    yield* this;
    return;
  }

  var count = 0;

  for (final o in this) {
    yield o;
    count++;
  }

  for (; count < length; count++) {
    yield padding;
  }
}
