2.0.4 16 Jun 2025
Release notes
- Fixed a bug on the Web platform where all devices were generating the same UUID (00000000-0000-4000-8000-000000000000)
- Implemented Web-specific UUID generation: attempts to generate a UUID using a browser fingerprint; if that fails, falls back to a randomly generated UUID using Dart
- The randomly generated UUID is stored in window.localStorage and reused across page reloads and browser sessions

2.0.0 15 Apr 2025
Release notes
- Breaking Change: getUniqueIdentifier() has been converted to a static method.
  - You can now call it directly without creating an instance:
    final deviceId = await UniqueDeviceIdentifier.getUniqueIdentifier();
  - This change simplifies usage but breaks compatibility with the previous instance-based approach:
    // ❌ This will no longer work: final deviceId = await UniqueDeviceIdentifier().getUniqueIdentifier();
