Performance Profiling

Optimizing your app's performance is crucial for a smooth and responsive user experience. Performance profiling is the process of analyzing your app's resource usage to identify bottlenecks.

A slow or laggy app can frustrate users and lead to uninstalls. We want our Flutter apps to run at a consistent 60 frames per second (fps), or 120 fps on supported devices, to feel fluid.

Flutter DevTools is a suite of debugging and performance tools for Flutter and Dart. It's your primary companion for understanding what's happening under the hood of your app.

You can launch DevTools from your IDE (like VS Code or Android Studio) or from the command line while your Flutter app is running. It opens in a web browser.
