Future<void> addToList<T>(
  1. String key,
  2. T item
)

Implementation

Future<void> addToList<T>(String key, T item) async {
  List<dynamic> list = await read<List<dynamic>>(key) ?? [];
  list.add(item);
  // Preservar tipo: si todos los elementos son String, guardar como List<String>
  if (item is String && list.every((e) => e is String)) {
    await write(key, List<String>.from(list));
  } else {
    await write(key, list);
  }
}
