Flutter App Player
App Player - browse designs and run Flutter code instantly
Flutter App Player - a mobile application where you can submit your design and browse the designs of others. Essentially the Player can compile any Dart code in seconds and run as a Flutter app right away, on the device. The speed of the app under execution is on par with runtime mode, so you get the same experience.

In addition, you can also paste a link to a code snippet, or scan it as QR code and get it running in a moment.
