February 2026 Highlights for getsentry/sentry-kotlin-multiplatform and getsentry/sentry-dart Key features delivered in February: - Kotlin Multiplatform agent development docs and build settings: Added AGENTS.md, CLAUDE.md symlink, and Claude Code settings, documenting agent-facing build commands, quality gates, repository structure, KMP conventions, and commit attribution to streamline Kotlin Multiplatform agent development. - Kotlin Multiplatform structured logging with Sentry integration: Implemented cross-platform logging with SentryLogger interface, platform-specific loggers for JVM and Apple, and SentryLog/SentryLogOptions for managing log entries. Added tests for log level conversions and attribute handling to ensure robust, typed logging across targets. - Dart telemetry and observability enhancements: Extended observability by syncing Dart traceId with native Android/iOS SDKs (setTrace propagation), wiring native setTrace across platform bindings, and introducing build-type telemetry. Removed guard around user data in logs to enable richer telemetry while maintaining safety. - Dart error reporting improvements: Added SDK name to native JavaScript error events to improve traceability of Dart-native-JS interactions. Major bugs fixed and stability improvements: - Resolved build and test stability issues across Flutter bindings and Kotlin Multiplatform tests, including improvements to test reliability for logging attributes and DSL utilities. - Addressed issues around attribute typing and logger lifecycle to prevent stale references after close/re-init cycles, improving reliability of cross-platform logging. Overall impact and business value: - Enhanced cross-platform observability and traceability across Dart/Flutter and Kotlin Multiplatform, unifying traces from Dart/native Android/iOS and JVM/Apple targets for faster incident investigation and analytics. - Improved developer onboarding and efficiency through agent development documentation and standardized build settings. - Strengthened error reporting and logging quality, enabling actionable insights for SRE and product teams. Technologies and skills demonstrated: - Kotlin Multiplatform: KMP agent development docs, structured logging with cross-platform loggers, Sentry integration, and DSL/readable attribute handling. - Dart/Flutter: Telemetry, trace propagation to native bindings (JNI, platform channels), and JS error metadata integration. - Build tooling, testing, and documentation practices, with cross-team collaboration (co-authored updates).
