New tooling releases — polish and stability (Flutter)
Here are the details for new tooling releases! The focus for this release is on polish and stability. There are quite a few changes to the UI — largely based on ongoing UX research — so this announcement is heavy on screen shots!
Performance Tooling Changes
The Performance tab in the inspector has been moved to a dedicated window, accessible from the bottom of the IDE, to accommodate new features such as the Rebuild stats table in the screenshot below. This table shows you widget rebuild counts on the current screen of your app and helps you locate the code responsible for rebuilding particular widgets.
The FPS display has been renamed to “Frame rendering time” to more accurately reflect its purpose. In addition, its tooltips have been improved. Toolbar actions have been reorganized, and various other changes improve usability.
We’d like to call out that many of the UI changes here were directly driven by user studies and feedback; thanks for all your input into the tooling!

Interacting with the Inspector while paused at a breakpoint was causing crashes. That’s been fixed. Plus, the error reporting for problems encountered in the Flutter tool has been improved. It now includes a stack trace from the Dart code in the Flutter tool.
Thanks for your reading.
