May 2026: Focused on reliability and clarity of WebSocket error handling in the Dart SDK. Implemented local-only error reporting for WebSocket.addError, ensuring errors are not transmitted to the remote peer; added regression tests to enforce local handling. The change reduces remote error leakage, decreases unnecessary network chatter, and improves developer confidence in error reporting workflow. This work demonstrates solid testing discipline, documentation updates, and collaborative code review across the SDK team.

April 2026: Delivered end-to-end Network payload size visibility in flutter/devtools. Implemented a new Size column in the Network tab and wired it through the data path from socket readBytes and HTTP content-length, through the data model to the UI. Refactored and centralized size formatting, added robust unit tests, and documented the changes. This work enhances network profiling capabilities, enabling quicker performance optimizations and more actionable insights for developers.
