[#breaking-changes](docId:-YQg4EDdAcW2uzhJCOZ6c)

- VUID configuration is now independent of ODP ([#78](https://github.com/optimizely/optimizely-flutter-sdk/pull/78))
- When VUID is disabled:
  - `vuid` is not generated or saved.
  - `client-initialized` event will not auto fired on SDK init.
  - `vuid` is not included in the odp events as a default attribute.
  - `createUserContext()` will be rejected if `userId` is not provided.
