first property

File 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

File get first {
  if (this.length > 0) {
    return JS('File', '#[0]', this);
  }
  throw new StateError("No elements");
}
void first= (File value)
inherited

Updates the first position of the list to contain value.

Equivalent to theList[0] = value;.

The list must be non-empty.

Implementation

void set first(E value) {
  if (length == 0) throw IterableElementError.noElement();
  this[0] = value;
}
