Getting Started

What is it?

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.

What can I do with it?

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.

How do I install it?

See the Android Studio, VS Code, and command line pages for installation instructions.
