Dart Flutter FAILURE: Build failed with an exception. Error

I took a few steps to publish my app on Play Store. Since making them, I've been getting errors when converting codes to APK.
I did the steps here: https://docs.flutter.dev/deployment/android#configure-signing-in-gradle
Error:
PS C:\Users\emiry\Desktop\KelimeOgren\kelimeogrenmeuygulamasi> flutter build appbundle

I will publish the app on Google Play Store.
https://docs.flutter.dev/deployment/android#configure-signing-in-gradle I did the ones in this link.
What is the problem? How can I solve it? Thank you very much in advance for the help.

Put both key.properties and key.jks files directly to the android folder , not inside src. And, in the key.properties file, do the following:
storePassword=secure
keyPassword=secure
keyAlias=key
storeFile=../key.jks

Flutter android release Build APK error: No signature of method

I was building the APK after checking that the flutter android app was normally run in the emulator.
I add Keystore and change: signingConfig.release in app:build.gradle
But it has an error: No signature of the method.
What is this problem?
This is app:build.gradle code

Could not find method implementation() for arguments [com.google.android.gms:play-services-instantapps:17.0.0] on project ':app'

I have the error I put in the title and put below. The error occurs when building my flutter project. I created my project with the Android Max 2D Game app on my Samsung Galaxy A10. I build by codemagic.

Can't build APK file in Flutter

I am trying to build an APK file using flutter, but I get this error although flutter run is working just fine.
I have tried the following with no result :
1- flutter clean.
2- delete the flutter inside src and reinstall it again
3- pub cache repair
I got the below error:

i find nothing on github or stackoverflow. have anyone a idea ?

try to migrate your project to androidX and if this doesn't work try to downgrade your flutter version to 1.9, I have got the same error and after I downgraded my flutter version it worked.
