      Android studioda açıkken böyle hata verdi

        SerkanKul Bunun kodlarla ilgisi olduğunu sanmıyorum.
        Androdi jdk ile iligili sorun var galiba

          evet suan kodlarla ilgili değil gradle ilgili sorunlar var

            firebase işlemleri varmı projede ?

            Studio ile sadece /android/ klasörünü tek aç synchronize edecektir studio.

              tamamen gradle sorunu bu ama aşamıyorum

              You are building a fat APK that includes binaries for android-arm, android-arm64.
              If you are deploying the app to the Play Store, it’s recommended to use app bundles or split the APK to reduce the APK size.
              To generate an app bundle, run:
              flutter build appbundle –target-platform android-arm,android-arm64
              Learn more on: https://developer.android.com/guide/app-bundle
              To split the APKs per ABI, run:
              flutter build apk –target-platform android-arm,android-arm64 –split-per-abi

              Projenizi çalıştıramamıştım. Bende gradle sorunu almıştım.
              IOS içinde aynı şeyi yaşadım ya
              Projede kullanılan bir pakete ya güncelleme gelmiş ya da kullanmka için native kod yazmak gerekiyor sanırsam.

                      ilki için flutter run kullanılması gerektiğini döylüyor . ama vscode terminalinde değil ..

                      ikinci için böyle bir şey mevcut .

                      bunlar dışında firebase ile işlem yaptığımda benzer sorunlar ile karşılaşmıştım
                      şunları izleyebilirsiniz.
                      android/gradle.properties dosyasına aşağıdakileri ekle;

                      android.useAndroidX=true
                      android.enableJetifier=true

                      ardından android/gradle/wrapper/gradle-wrapper.properties dosyasında surumu güncelle
                      distributionUrl=https\://services.gradle.org/distributions/gradle-5.4.1-all.zip

                      devamında android/build.gradle gradle builde versionunu 3.5.1 yap

                      classpath 'com.android.tools.build:gradle:3.5.1'

                      sonrasında android/app/build.gradle dosyasında defaultConfig kısmında multiDexEnabled eklemen gerek.

                      multiDexEnabled true

                      sorun çözülmesi lazım…
                      eğer hata verirse Android Studio ile uygulamanın sadece androis dosyasını aç . Studio onu sycronised edecektir..
