Error whilst building apk

When trying to build an apk using the flutter build apk command I am getting this error, building an appbundle works fine however.

flutter build apk

The error you are encountering (resource android:attr/lStar not found) occurs because the lStar attribute was introduced in a newer version of Android (API 31), but your project or one of its dependencies, like mixpanel_flutter, might be using an older version of compileSdkVersion that does not support this attribute.

To resolve this issue, you need to ensure that your project is using a compileSdkVersion that is compatible with the lStar attribute.

1.  Update compileSdkVersion and buildToolsVersion:

subprojects {
    afterEvaluate { project ->
        if (project.plugins.hasPlugin("com.android.application") ||
                project.plugins.hasPlugin("com.android.library")) {
            project.android {
                compileSdkVersion 34
                buildToolsVersion "34.0.0"
            }
        }
    }
}

This ensures that all subprojects in your application use these versions of the SDK and build tools.

2.  Clean and Rebuild the Project:

After making these changes, perform a clean and rebuild of the project to apply the new configuration:

flutter clean
flutter build apk
