Flutter DevTools

Performance tools for Flutter.

What is this?

This repo is a companion repo to the main flutter repo. It contains the source code for a suite of Flutter performance tools.

But there's not much here?

It's still very early in development - stay tuned.

Issues

Please file any issues, bugs, or feature requests in the main flutter repo.

Trying it out

• git clone https://github.com/flutter/devtools
• cd devtools
• pub get
• pub global activate webdev

From a separate terminal:

• cd <path/to/flutter-sdk>/examples/flutter_gallery
• ensure the iOS Simulator is open (or a physical device is connected)
• flutter run

From the devtools directory:

• webdev serve

Then, open a browser window to the local url specified by webdev. After the page has loaded, append ?port=xxx to the url, where xxx is the port number of the service protocol port, as specified by the flutter run output.
