My Flutter application feels sluggish—screens hesitate before reacting to taps and the initial launch drags longer than it should. I need a developer who can dive into the codebase, pinpoint the bottlenecks, and leave the app noticeably more responsive. Key focus • Improve overall UI responsiveness (animation jank and frame drops must disappear). • Shorten the first-time startup lag. I’m expecting you to profile the current build (DevTools, Dart Observatory, etc.), propose concrete fixes, implement them, and provide before-and-after metrics so we can see the gains on both iOS and Android. Deliverables 1. Optimized code committed to my Git repo. 2. Performance report showing FPS, frame build times, and cold-start duration before vs. after. 3. A concise walkthrough of the changes so I can maintain them going forward. No design or feature work is required—just streamlined, buttery-smooth performance.
