Worked on the linagora/tmail-flutter repository to enhance debugging capabilities for Flutter Web applications by integrating source maps into the web build process. This feature allows developers to trace runtime errors directly back to the original Dart source code, streamlining issue diagnosis and improving maintainability. The technical approach involved modifying the Docker-based build pipeline and leveraging Flutter’s web tooling to generate and include source maps. No bugs were addressed during this period, as the focus remained on feature development. The work strengthened the project’s foundation for future monitoring and error reporting, utilizing skills in Docker, Flutter, and Dockerfile configuration.
