Android Crash: Missing Stripe PaymentSheet GooglePayConfiguration ButtonType Class

I'm encountering an Android-only crash when initializing the Flutter Stripe PaymentSheet, with the error indicating that the class "com.stripe.android.paymentsheet.PaymentSheet$GooglePayConfiguration$ButtonType" is missing. I have followed all the integration steps, and the payment process works fine on iOS, but the Android build fails. Below is the relevant code and manifest snippet that I used:

DARTCopied
Future<void> openPaymentSheet() async {
 try {
  Map<String, dynamic> paymentIntentData = await callPaymentIntentApi('200', 'USD');
  print(paymentIntentData);
  UpPrint(name: "CheckSecretKey", value: paymentIntentData['client_secret'].toString());

  var gPay = const PaymentSheetGooglePay(merchantCountryCode: "US",
    currencyCode: "USD",
    testEnv: true);

  await Stripe.instance
    .initPaymentSheet(
      paymentSheetParameters:  SetupPaymentSheetParameters(
        paymentIntentClientSecret: paymentIntentData['client_secret'],
        googlePay: gPay,
        style: ThemeMode.system,
        merchantDisplayName: 'MyProject',
      )
    )
    .then((value) {
      showPaymentSheet();
    });
 } catch (e, s) {
   print('Exception:$e$s');
 }
}

Future callPaymentIntentApi(String amount, String currency) async {
 try {
   Map<String, dynamic> body = {
     'amount': calculateAmount(amount),
     'currency': currency,
   };
   print(body);
   var response = await http.post(
     Uri.parse('https://api.stripe.com/v1/payment_intents'),
     body: body,
     headers: {
       'Authorization': 'Bearer ${UpConfigure.secretKey}',
       'Content-Type': 'application/x-www-form-urlencoded'
     }
   );
   return jsonDecode(response.body);
 } catch (err) {
   print('callPaymentIntentApi Exception: ${err.toString()}');
 }
}

The error in the logs is as follows:

E/AndroidRuntime( 1947): java.lang.NoClassDefFoundError: Failed resolution of: Lcom/stripe/android/paymentsheet/PaymentSheet$GooglePayConfiguration$ButtonType;

Additional log lines:
E/AndroidRuntime( 1947): at com.reactnativestripesdk.PaymentSheetFragment.(PaymentSheetFragment.kt:360)
... (stack trace continues) ...

Here is the snippet from my manifest file:

XMLCopied
<intent-filter android:autoVerify="true">
  <action android:name="android.intent.action.VIEW"/>
  <category android:name="android.intent.category.DEFAULT" />
  <category android:name="android.intent.category.BROWSABLE" />
  <data android:scheme="flutterstripe" android:host="safepay" />
</intent-filter>

I've completed all the integration steps, but I'm still facing this issue on Android. Could someone point out what might be missing or misconfigured in my setup? Thanks in advance!
