tryGetList<T> method

List<T>? tryGetList<T>(
  1. int index, {
  2. List<int>? alternativeIndices,
  3. dynamic innerMapKey,
  4. int? innerIndex,
  5. List<T>? defaultValue,
  6. ElementConverter<T>? elementConverter,
})

Tries to convert the element at index (or fallback indices) to a List of T.
