Tiny Flutter: The future of Dart & Flutter on small devices?

Dart recently added experimental support for the new RISC-V CPU architecture and the first boards with these new chips are now starting to be available. One of these is the Sipeed Lichee D1, a RaspberryPi type device that is able to run Linux and Dart. At the same time, tiny but very cheap OLED screens are showing up in all sorts of devices, from soldering irons to high end music synthesizers. But what does it mean for Flutter and its mission "Beautiful apps for every screen" when the screen is 1 inch with a resolution of 128x64? Is that even possible?

Blocking behaviors include hiding elements, blocking loads, and, on iOS and macOS, stripping cookies from WebView requests.
