}

I faced the same error.
In my case, the key.properties was missing.
I just added it in [project]/android/key.properties
The content of key.properties was;
storePassword=<password from previous step> (example: 12345678)
keyPassword=<password from previous step> (example: 12345678)
keyAlias=upload
storeFile=/Users/<user name>/upload-keystore.jks (Complete path of upload-keystore.jks
using "/" not "\")
After this I run this command to build the app bundle;
flutter build appbundle

Be sure that you use invalid key name and password
Use key path ended with ".jks" in your key.property
If failed create another release key with new alias
Downgrading the kotlin version and gradle plugin did it for me after that flutter clean && flutter pub get && flutter run

Build Gradle Could not find method signingConfigs() for arguments [build_al27st8bbmybmo7hiqzirqbvw$_run_closure2#2176e371]

I want to publish the app in the google play store and I get this error.
Most of the things were done by flutter_automation and I use api 28 for the android system.
When I try the command build flutter app bundle this error appears and I don't get any bundle created.
I cant build my flutter app bundle because of this error:
