Whether the collection contains an element equal to element.
inherited
elementAt(int index) → T
Returns the indexth element.
inherited
elementAtOrNull(int index) → T?

Available on Iterable<T>, provided by the IterableExtensions extension

The element at position index of this iterable, or null.
emit(ListFieldBlocState<T> state) → void
Updates the state to the provided state. emit does nothing if the state being emitted is equal to the current state.
inherited
