Changelog

All notable changes to this project will be documented in this file.

2.0.0

• 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();
    

1.0.0

• Initial release of the unique_device_identifier Flutter plugin.
• Supports the following platforms:
  • ✅ Android (Settings.Secure.ANDROID_ID)
  • ✅ iOS (UIDevice.identifierForVendor)
  • ✅ Windows (MachineGuid from registry)
  • ✅ macOS (IOPlatformUUID via IOKit with macOS 12+ fallback)
  • ✅ Linux (/etc/machine-id)
  • ✅ Web (fingerprint-based hash with fallback to random UUID, stored in localStorage)
• No external dependencies required.
• Provides a consistent getUniqueIdentifier() interface for all platforms using MethodChannel and Dart interop.
