Beginne mit der Prüfung der F-Droid-Scanner-Ausgabe für edu.rit.csh.devin_5.apk und des verlinkten Flutter-Issues. Verfolge die Quelle der aufgeführten com/google/android/play/core-Klassen in der Android-Build-Konfiguration; als abgeschlossen gilt die Aufgabe, wenn der F-Droid-Build diese nicht freien Google-Play-Klassen nicht mehr enthält oder meldet.

Vom Indexierungsmodell aus dem Issue-Text verfasst.
