In this directory, you'll find samples that target Flutter's master channel. They may take advantage of new SDK features that haven't landed in the stable channel, and they may crash, lock up your machine, or otherwise fail to run correctly. In other words, consider everything in this directory to be an experiment.

We're maintaining these samples here so that folks can see some of Flutter's upcoming features as they evolve and get a sense for how they'll eventually be used. If you'd like to run the apps, make sure to switch to the master channel first:

flutter channel master
flutter upgrade

When you're done, use this command to return to the safety of the stable channel:

flutter channel stable
