- Diagnose UI jank performance issues in a Flutter app.
- Source-level debugging of a Flutter or Dart command-line app.

How do I install DevTools?
How do I try DevTools written in Flutter?
To test the alpha version of DevTools written in Flutter, click the “beaker” icon in the upper-right corner of DevTools. This will launch DevTools running on Flutter web. This version is in early preview with only the inspector tab feature complete. It is under active development.
Please give DevTools a try, provide feedback, and file issues in the DevTools issue tracker. Thanks!
For more information on using DevTools with Dart command-line apps, see the DevTools documentation on dart.dev.
