writeCount method
Writes values into the array this field points to, within the struct
at p. The pointed-to memory must already be allocated with room for
at least values.length elements (see allocate).
Returns values.
Throws StateError if the codec doesn't support contiguous arrays.
Implementation
List<E> writeCount(MemoryPointer p, List<E> values) {
final ref = codec.deref(p.offsetBy(offset));
if (ref.isNull) return values;
_innerArray().writeArray(ref, values);
return values;
}
