data_ext library

Data structures to represent data objects and arrays with JSON integration.

DataObject can represent data like JSON Objects or properties as a map. DataArray can represent data like JSON Arrays or properties as a list.

This package is same as the package:attributes/data.dart but contains also base implementation classes to help implementing data object and array classes.

DataObjectView implements DataObject and is a default implementation for viewing data objects.

DataArrayView implements DataArray and is a default implementation for viewing data arrays.

Both DataObjectView and DataArrayView can be extended by external code packages as necessary.

Usage: import package:attributes/data_ext.dart
