2.0.2 — 2026-04-29

Fixed

• Fixed a critical packaging issue where core source files were located outside the lib/ directory, causing import failures when using package:nebula_db/....

• Resolved multiple "file not found" errors affecting modules such as:

  • engine/
  • sql/
  • storage/
  • catalog/
  • index/

• Fixed invalid exports in nebula_db.dart that referenced non-existent or unpublished files.

Changed

• Reorganized the project structure to comply with Dart package conventions:

  • Moved all source files under the lib/ directory

• Established a clean public API entry point:

  • lib/nebula_db.dart

Improved

• Full compatibility with:

  • Flutter (Windows, Web, Android)
  • Dart package resolution system (pub get, pub.dev)

• Improved developer experience when integrating the package via pub.dev or local path dependencies
