When uploading a flutter App to Google Play, I get the following error:
We've detected this app uses an unsupported version of Play billing. Please upgrade to Billing Library version 3 or newer to publish this app. Learn More about Billing Library 3.
I have updated the app/build.gradle dependencies with this:
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
def billing_version = "4.0.0"
implementation "com.android.billingclient:billing-ktx:$billing_version"
}
I am using purchases_flutter plugin:
purchases_flutter: ^3.4.5
I have also run flutter clean multiple times.
Here is my flutter doctor output:

I can't create any Subscription because of this.
Any help is appreciated!

Publishing your Flutter app to Google Play and Apple App Stores. A few lessons I learnt the hard way! The real magic in Flutter is the ease in which it can create multiple production-ready binaries from a single code base.
During a typical development cycle, you test an app using flutter run at the command line, or by using the Run and Debug options in your IDE. By default, Flutter builds a debug version of your app. When you’re ready to prepare a release version of your app, for example to publish to the Google Play Store , this page can help.
Flutter is a Google's UI kit, made for cross-platforms, meaning that with just one set of codes, it can be used to run in Android, iOS, and Web. Pretty neat, right? Anyways, I've been hitting my keyboard here and there, and was lucky enough to create two simple apps and deploy it on both Play Store and App Store.
Supported in versions 4.0 and higher of the Google Play Billing Library, Google Play allows customers to purchase more than one of the same in-app product in one transaction by specifying a quantity from the purchase cart. Your app is expected to handle multi-quantity purchases and grant entitlement based on the specified purchase quantity.
Add this dependency in your app/build.gradle file
implementation 'com.android.billingclient:billing:3.0.0'
This works for me.
