ValueAt method

P ValueAt(String key, [ String? text, int? bufferSize ])

Returns the P for the keyed slot key, optionally writing text into it.

Allocates the slot on first use. If text is null the existing string is returned; asserts that the slot has been initialised at least once.

Implementation

P ValueAt(String key, [String? text, int? bufferSize]) {
  final slot = stringSlotsKeyed.putIfAbsent(
    key, () => stringSlots.length
  );

  _ensureSlotExists(slot);

  if (text != null) {
    return writeToSlot(slot, text, bufferSize);
  }

  assert(
    !isPointerNull(stringSlots[slot]),
    '[TEMP] String.ValueAt("$key") used before initialization'
  );

  return stringSlots[slot];
}
