How do you approach performance optimization in mobile apps built with Flutter or React Native?

Question

Coco Maiolo · Accepted Answer

I recently updated mine, so it’s less than a year old. Do you think a more recent photo has a better impact?

Answer

Flutter has some nice built-in performance profiling tools like the Timeline view and Flutter inspector. For React Native, I've found the React DevTools profiler super helpful for identifying perf bottlenecks. Beyond that, common strategies like lazy loading, avoiding unnecessary re-renders, and optimizing expensive calculations go a long way. Oh and make sure your app bundles are tree-shaken and minified for prod!

Answer

Mine is more than 3 years old! I guess I should consider refreshing it soon.

Answer

Keep mine updated every year. What’s your strategy for updating your LinkedIn profile picture?

Answer

With React Native, I usually start by using native modules for heavy tasks and keep an eye on reducing unnecessary renders to keep the app smooth.

Answer

For Flutter, I focus on minimizing widget rebuilds and optimizing animations. Profiling tools are super helpful to spot performance bottlenecks

When optimizing mobile apps with Flutter or React Native, I concentrate on reducing unnecessary renders and leveraging efficient state management

Answer

My strategy involves minimizing the use of expensive operations during rendering and optimizing the state management. I also make use of lazy loading and asynchronous operation to improve performance.

Performance optimization in mobile apps developed with Flutter or React Native focuses on efficient state management, minimizing unnecessary rendering, and leveraging appropriate libraries for animations and network handling. For instance, Flutter's const widgets and React Native's memoization techniques help streamline performance by reducing rebuilds. This article https://www.cogniteq.com/blog/fl... on Flutter's pros and cons offers valuable insights into how Flutter’s capabilities can influence app efficiency. Ensuring smooth animations and optimizing native integrations for demanding tasks like media processing is also crucial for delivering high-performing applications.

One thing I do is to make sure we’re only building what’s necessary. For me, keeping the widget tree simple and avoiding unnecessary complexity can make a big difference.

Answer

I tackle performance  optimization by focusing on efficient component rendering and managing state effectively. For Flutter, I use the DevTools suite, and for React Native, I rely on tools like Flipper.

I usually profile the app to identify performance bottlenecks, then optimize code in those areas - things like minimizing re-renders, caching data, and using async operations. Also make sure to test on lower-end devices. What specific techniques have worked well for you?

Mae Twyman · Answer

I make sure to optimize images and assets in both Flutter and React Native apps. Lazy loading and caching strategies go a long way in improving performance.
