Since we last saw you, we released Flutter 1.0! We celebrated with a major upgrade to the Shrine demo. We also added an Elevations demo to the Material gallery, plus example code for many Material samples. We expanded the Cupertino section with new pickers and a textfield demo. Behind the scenes, we upgraded the gallery to use the latest Flutter framework, which shrunk the app size down by another couple of megabytes, and we fixed a few bugs here and there.
