Here are several ways to measure the performance of your Flutter application:
1. DevTools Performance View:
This is a built-in tool within Flutter DevTools that allows you to analyze frame rendering times and identify performance bottlenecks. It provides valuable insights like:
Flutter frames chart (visualizes frame rendering times)
Frame analysis tab (details on individual frames)
Raster stats tab (statistics on rasterization)
Steps:
Ensure you're running your app in profile mode (not debug mode) for accurate performance measurement. Use flutter run --profile command.
Launch Flutter DevTools (usually by shaking your device or using the menu option in your IDE).
Navigate to the Performance view.
2. Observatory:
Observatory is a powerful tool for analyzing your Dart application's performance and memory usage. It offers features like:
Inspecting the heap snapshot to identify memory leaks
Profiling CPU usage to pinpoint performance bottlenecks
