+## Migration from Unity 2022 to Unity 6.
+The 6000 version is currently based on a 6000 branch in the original repo. See [this issue](https://github.com/juicycleff/flutter-unity-view-widget/issues/967) for more details.
+
+Make sure to import a new unitypackage of version 6000.x.y. 
+
+### Android
+In short:  
+1. Follow the regular android setup like in the readme.  
+But for Android do **NOT** use `ndk.dir=` in `local.properties`.  
+Use the `ndkVersion = "<ndk version number here>"` in build.gradle approach.
+
+1. Your Flutter project will need to use Java 17 and gradle 8.x to match the versions used by Unity. 
+
+Try to match or exceed these gradle and AGP versions:
+
+| Unity Version                     | Gradle Version  | Android Gradle Plug-in Version | NDK                  | JDK |

+
+Check [the Unity documentation](https://docs.unity3d.com/6000.0/Documentation/Manual/android-gradle-version-compatibility.html) for any updates. You can change the editor version in the top left.
+
+
+3. Make sure to import a 6000.0.x unitypackage into your Unity project. The export scripts have been updated.
+
+2. Make sure to delete any old exports in `ios/UnityLibrary` and `android/unityLibrary` before making a new export.
