When I compile the app with Visual Studio Code it gives me the following error:

e: C:\Projects\flutter.pub-cache\hosted\pub.dartlang.org\flutter_foreground_task-3.5.0\android\src\main\kotlin\com\pravera\flutter_foreground_task\service\ForegroundService.kt: (210, 53): Unresolved reference: S

#15 (comment)

Use the 'flutter clean' command as shown on this page.

I also have this issue and flutter clean doesn't seem to fix it.
I tried running flutter clean multiple times, together with the other steps mentioned in #15 But they don't work for my project.

I also tried it on the example, where I first changed the pubspec.yaml file to not get this package from ../, and there, indeed, the issue was fixed after running flutter clean.

Do you have any clue why this fix doesn't work on my project?

@erueloi, @Ruud14

Can you try setting the compileSdkVersion and targetSdkVersion values ​​to 31 in the app level build.gradle file?

android {
    compileSdkVersion 31

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    defaultConfig {
        applicationId "com.pravera.flutter_foreground_task_example"
        minSdkVersion 23
        targetSdkVersion 31
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }

    ...
}

And add the exported option to the MainActivity tag of the AndroidManifest file.

        <activity
            android:name=".MainActivity"
            android:launchMode="singleTop"
            android:theme="@style/LaunchTheme"
            android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
            android:hardwareAccelerated="true"
            android:windowSoftInputMode="adjustResize"
            android:exported="true"> // here
