Flutter version

3.32.6

Description

If you launch play mode with the build target set to iOS, calling SendToFlutter.send will trigger the following error.

EntryPointNotFoundException: FlutterEmbedUnityIos_sendToFlutter assembly:<unknown assembly> type:<unknown type> member:(null)
SendToFlutter.Send (System.String data) (at Assets/FlutterEmbed/SendToFlutter/SendToFlutter.cs:21)

Fix

Simply checking if we are in the Unity Editor fixes this:

-#if UNITY_IOS
+#if UNITY_IOS && !UNITY_EDITOR
            // Call an obj-C function name
            FlutterEmbedUnityIos_sendToFlutter(data);
#endif

Minimum reproducible example (MRE)

Just run the example Unity project in the Unity Editor, with build target iOS.
The AR check will immediately send a message to Flutter, which triggers this error,

Happens on both 2022.3.62 and 6000.1.11
