We probably need a mechanism here for handling large arrays, so that the content
can be partial, and more elements can be fetched in batches.

Please open an issue on this.

I made an issue and a TODO.

+  /// An [Array] describing the remote instance.
+  final ArrayStructure array;
+
+  /// The values of the array as [DartValue]s of the remote instance.
+  final List<DartValue> values;
+
+  RemoteArray(this.array, this.values, {String name}) : super(name);
+}
+
 /// A representation of a remote primitive value (i.e. used for non-instances).
 class RemoteValue extends RemoteObject {
   /// A [DartValue] describing the remote object.
   final DartValue value;
 
   RemoteValue(this.value, {String name}) : super(name);
   bool get isError => false;
 }
 
 /// A representation of a failure to retrieve a remote object.
