Key Points
- The article provides senior-level interview questions focused on production-grade AI agent architecture, using a real-world Flutter chat streaming bug scenario as the core case study.
- It asks candidates to design a generic streaming state update mechanism for SSE-delivered AI responses that correctly handles packet out-of-order/latency, Markdown truncation causing rendering failures, and concurrent state update race conditions.
- The expected solution emphasizes decoupling “backend data reception” from “UI rendering” via an accumulator pattern with immutable state updates and buffering for stream fragments.
- It also requests key state-management code logic and an accompanying logging design to quickly determine whether failures originate from backend stream cessation or front-end rendering logic errors.
- A pseudocode example introduces a StreamMessageHandler concept with chunk validation/logging, incremental content accumulation, and UI-triggering state updates to avoid overwriting or partial-only display issues.
