Jankiness and performance degradation on mid-range devices in production

7/10 High

Apps that run flawlessly during development exhibit performance issues on real mid-range Android devices. Causes include excessive widget rebuilds, unoptimized images, synchronous main-thread operations, and unclosed streams. Flutter's reactive nature amplifies these problems in poorly structured widget trees.

Query: “What are the most common pain points with Flutter for developers in 2025?”4/4/2026

I have debugged apps that were flawless during development, but exhibited jankiness on real devices, particularly the mid-range Android phones that continue to dominate in emerging markets. The culprits? Excessive widget rebuilds, unoptimized images, synchronous operations on the main thread, and memory leaks from unclosed streams.
