I could reproduce this error in Flutter 3.10.5 as well:

Flutter 3.10.5 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 796c8ef792 (5 weeks ago) • 2023-06-13 15:51:02 -0700
Engine • revision 45f6e00911
Tools • Dart 3.0.5 • DevTools 2.23.1

Solution

Please, update your gradle version from ext.kotlin_version = '1.7.10' to ext.kotlin_version = '1.8.0' in /android/build.gradle.

And you'll be able to build successfully:

√  Built build/app/outputs/flutter-apk/app-release.apk (18.4MB).

---

The error cause is because the shared_storage is using kotlin version 1.8.x and it leads to conflicts within flutter projects using kotlin version 1.7.x.
