How can I solve this problem This problem occurs every time a FLUTTER build occurs flutter 2.10.1 Dart SDK version: 2.16.1 (stable) (Tue Feb 8 12:02:33 2022 +0100) on "windows_x64"

In app/build.gradle change jdk7 to Java jdk8

before

dependencies {
 implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
}

after

dependencies {
 implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"
}

  • thanks ... ```flutter build apk --release``` shows no Issue found but now it is stuck at ```Running Gradle task 'assembleRelease'...``` – Ali Yar Khan Apr 30 '22 at 15:34
