cachedCursorContainerId property

String? get cachedCursorContainerId

O(1) when pre-computed, falls back to O(1) cache-miss otherwise.

Implementation

String? get cachedCursorContainerId {
  return _cachedCursorContainerId ??
      (cursor.focusId.isNotEmpty
          ? findLogicalContainerId(cursor.focusId)
          : null);
}
