MessagesListController<T extends MessageBase> class

A class that manages the item list; as such, this class should be the only one holding the list of items it controls You should perform all add/remove items with the api this class provides. This class also handles click management: longPressing an item will select it; tapping an item will toggle its selection if isSelectionModeActive is true. Listen to selectionEventStream to catch any selection event SelectionEvent. Make sure to call MessagesListController.dispose when disposing the widget.
