GokhanKutlu android sdk’yı yüklemeyi tekrar deneyin

Yeni kullanici olarak ne yapsam da emulator sirununu cozemedim.
iki çözüm yolu buldum:

1. Asagidaki konudaki emulatoru yuklemek.
   https://www.flutterforum.org/d/153-en-iyi-android-emulator

2. Telefonu pcye takip, tellefonu emulator olarak kullanmak. Android Telefonunuz varsa bunu tavsiye ederim.

yigidoyum Hocam normalde hangi emülatörü kullanıyordunuz da hata aldınız ?
