 ### Features
 
+- Add API for pausing/resuming **iOS** and **macOS** app hang tracking ([#2134](https://github.com/getsentry/sentry-dart/pull/2134))
+  - This is useful to prevent the Cocoa SDK from reporting wrongly detected app hangs when the OS shows a system dialog for asking specific permissions.
+  - Use `SentryFlutter.pauseAppHangTracking()` and `SentryFlutter.resumeAppHangTracking()`
 - Capture total frames, frames delay, slow & frozen frames and attach to spans ([#2106](https://github.com/getsentry/sentry-dart/pull/2106))
 - Support WebAssembly compilation (dart2wasm) ([#2113](https://github.com/getsentry/sentry-dart/pull/2113))
