Thanks for the reply! Just to clarify, even though the main app is built with Flutter, the Live Activity and widget extension are fully native Swift/SwiftUI and built in Xcode. The issue seems to be on the ActivityKit/WidgetKit side rather than the Flutter side. I’ve gone through Apple’s Live Activity tutorial and everything works except the actual UI rendering (Dynamic Island shows a black capsule even though the regions contain simple Text/Image views with no errors). I’m mainly hoping someone who’s run into a similar ActivityKit rendering issue can point out anything I may be missing in the widget extension setup. Any insights are appreciated!

The Live Activity does launch and when pressed takes user back into the correct app.
