  "summary": "This article provides a detailed guide on optimizing Flutter applications for Meta Smart Glasses, focusing on backpressure, frame pacing, and event coalescing. The tutorial emphasizes the importance of separating acquisition from presentation and keeping safety-critical control loops on the robot. It recommends defining measurable service objectives, such as freshness, event-to-display latency, throughput, and battery usage, while avoiding the reliance on a single FPS number. The article also suggests instrumenting the complete path of sensor capture and Flutter event handling, establishing a repeatable baseline for profiling, and implementing bounded buffering with overflow policies to protect the Flutter frame budget.",
