Array method
Writes array into a slot of sufficient capacity and returns the pointer.
key defaults to 'default'. The slot is grown automatically if the
current capacity is smaller than array.length.
Implementation
Pointer<T> Array(List<X> array, {String? key}) {
final p = At(_slotKey(key), array.length);
for (int i = 0; i < array.length; i++) indexSetterFunc(p, i, array[i]);
return p;
}
