Time for Flutter on the Apple Watch
summary
Shows how a Flutter app syncs live state with an Apple Watch using Apple's WatchConnectivity and the pub package flutter_watch_connectivity, with phone → watch updates via applicationContext and a phone-side stream back to the app. Demonstrates incrementing a counter on one device and seeing it on the other, sending files (screenshots) as a screenshot-as-file hack while warning that received files are ephemeral so must be saved, and adding a watch complication widget extension (needs an app group). Notes an Apple API quirk that complications documentation is unreliable.
