#flashlight react native

Today's Talk introduces Flashlight, a tool for measuring mobile app performance. Flashlight provides a performance report that highlights issues like high CPU usage on low-end devices. To fix these issues, the Shopify component Flashlist can be used. Flashlight can also be used locally to measure performance changes in React Native apps, with the ability to see the score rapidly changing and improved performance after implementing fixes. More information can be found in the documentation and an article comparing scrolling performance in React Native.
