first property

E first
override

Returns the first element.

Throws a StateError if this is empty. Otherwise returns the first element in the iteration order, equivalent to this.elementAt(0).

Implementation

E get first {
  if (isEmpty) {
    throw StateError('No such element');
  }
  return _first!;
}
