version property
version
The identifier that is used to identify this version of the
terminology capabilities when it is referenced in a specification,
model, design or instance. This is an arbitrary value managed by the
terminology capabilities author and is not expected to be globally
unique. For example, it might be a timestamp (e.g. yyyymmdd) if a
managed version is not available. There is also no expectation that
versions can be placed in a lexicographical sequence.
Implementation
String? get version => throw _privateConstructorUsedError;
