My gradle version is actually 6.1.1.
Here is my gradle-wrapper.properties from android/gradle code:
...
distributionUrl=https\://services.gradle.org/distributions/gradle-6.1.1-all.zip

I have tried to change the version to 5.4.1 but I got a similar error:

If someone could help me I would be grateful!

Answer 1

After one month of struggle I found how to solve the problem:
I have changed gradle version from android/gradle/wrapper/gradle-wrapper.properties from 6.1.1 to 5.6.2 . So my file looks like:
...
distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.2-all.zip
...
In android/build.gradle I have changed gradle tool version from 4.0.0 to 3.5.0:
dependencies {
classpath 'com.android.tools.build:gradle:3.5.0'
...
}
In android/app/build.gradle I have added checkReleaseBuilds false to lintOptions :
lintOptions {
...
checkReleaseBuilds false
}
In android/app/appcenter-post-clone.sh I have added two builds before --release build:
...
# build APK
flutter build apk --debug
flutter build apk --profile
flutter build apk --release
...
I hope this will help others :)
