Flutter Uygulaması Apk Oluştururken Hata Alıyorum?

Merhabalar CodeCanyondan bir uygulama satın aldım. Uygulama çalışıyor hatta direk android studio ile apk oluştururken hata almıyorum ancak ne zaman dosyaları değiştirsem (uygulama ismi,Package name ) vs gibi sonra apk oluştururken bu hatayı alıyorum. Bunun çözümünü bilen yada fikri olan varsa yazar mısınız?
- Şimdiden yardımcı olan herkese teşekür ederim

Aldığım Hata
