Flutter and Apple Watch
We have started experimenting and playing around with adding a Watch Kit app to a Flutter build. We now have this working, but it gets a bit complicated because the Flutter tooling will not allow an iOS app to be run or built when it contains a Watch Kit target (well not yet anyway).
From this exercise , which resulted in a fully working demo app HERE, we have now started looking at creating a more generic plug-in package for Flutter which can expose some of the Watch Kit functionality through a standard interface.
This is still W.I.P. but the demo screen shown below details a working plug-i that exposes the SendMessage functionality to Flutter.
