Welcome to our Data Visualization demo for Flutter Web. This was part of the initial set of demos for Flutter Web when it was announced at Google I/O 2019. This project uses activity data from the main Flutter github repository over the four year lifespan of the project, then plots it in an animated layered chart.

More details are available on the project page on our website.

How to run the app

Generally just follow the instructions at https://github.com/flutter/flutter_web, but the following steps are usually enough:

1. Install the flutter_web build tools:

   $ flutter pub global activate webdev
   

2. Update packages.

   $ flutter packages upgrade
   ! flutter_web 0.0.0 from path ../../flutter_web
   ! flutter_web_ui 0.0.0 from path ../../flutter_web_ui
   Running "flutter packages upgrade" in hello_world...                5.0s

   If that succeeds, you're ready to run it!

3. Build and serve the example locally.

   $ webdev serve
