Document class Null safety

Allows storage of unstructured data in a ManagedObject property.

Documents may be properties of ManagedObject table definition. They are a container for data that is a JSON-encodable Map or List. When storing a Document in a database column, data is JSON-encoded.

Use this type to store unstructured or 'schema-less' data. Example:

    class Event extends ManagedObject<_Event> implements _Event {}
    class _Event {
      @primaryKey
      int id;

      String type;

      Document details;
    }
