Dart DevTools is a suite of performance tools for Dart and Flutter. It‘s currently in preview release, but we’re actively working on improvements and on shipping new versions.
DevTools supports inspecting the UI layout and state of a Flutter app, diagnosing UI jank performance issues in a Flutter app, source-level debugging of a Flutter or Dart command-line app, and viewing general log and diagnostics information about a running app.
We expect developers to use DevTools in conjunction with their existing IDE or command-line based development workflow.

DevTools is currently in a preview release stage. Please try it out, and provide feedback and file issues at github.com/flutter/devtools/issues. Thanks!
