- * Growable typed-data lists.
- *
- * These lists works just as a typed-data list, except that they are growable.
- * They use an underlying buffer, and when that buffer becomes too small, it
- * is replaced by a new buffer.
- *
- * That means that using the [TypedDataView.buffer] getter is not guaranteed
- * to return the same result each time it is used, and that the buffer may
- * be larger than what the list is using.
