No More Anxiety: How to Use iOS Extensions in Your Flutter App
summary
Shows a working action/share extension built with storyboard UI that reads an image attachment, writes the file into an app group container, saves a small metadata object to shared UserDefaults, and opens the host app via a deep link to hand the data off. Explains required Xcode fixes like reordering build phases and setting NSExtension activation rule: image max count=1, and demonstrates embedding a Flutter engine in extension with the caveat of a 100 MB limit so use debug simulator and careful profiling.
