Veli bey selamlar, nasılsınız?
Sizi youtube ve google dsc eğitimlerinden biliyorum.

Ben flutter upgrade yaptıktan sonra bu hatayı almaya başladım. Google search yaptım çözüm olarak karşıma çıkan her şeyi denedim. flutter clean, paketlerin vesiyonları, compileSdk versiyonu, kotlin versiyonu, pub cahce repair, jdk sürümü yükselttim,tekrar downgrade yaptım olmadı, aynı hata devam ediyor. Belki de ben yaptıklarımı düzgün yapamadım. Son çare sizin issue lara bakıyorum dediğiniz aklıma geldi o yüzden buradayım.
Umarım günlerdir savaştığım şu sorununun çözümü sizdedir, teşekkürler şimdiden :)
