ParseLiveListWidget<T extends ParseObject> class
A widget that displays a live list of Parse objects.
The ParseLiveListWidget is initialized with a query that retrieves the
objects to display in the list. The childBuilder function is used to
specify how each object in the list should be displayed.
The ParseLiveListWidget also provides support for error handling and
lazy loading of objects in the list.
