I have error with external libs for my flutter project. When I run my project as a debug version everything is working okay, but when I run my project as a release version then I have issue like below. I tried to change compileSdk version, but it's not helped. I tried to change buildType, but still not working. Problem is with 2 libraries:
android_package_manager: ^0.6.0
flutter_logs: ^2.1.11
App gradle:
def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
localPropertiesFile.withReader('UTF-8') { reader ->
localProperties.load(reader)
}
}
def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}
def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
flutterVersionCode = '7'
}
def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
flutterVersionName = '2.7.0'
}

This is a problem with the android_package_manager package that you use. If you look at its build.gradle file, you'll notice it's missing namespace which is required as of Android Gradle Plugin v8.
Alternatively you can downgrade to AGP v7 and Gradle v7, but I don't recommend doing that, unless for a brief moment (if you're in an emergency situation).
