• OS: Android 14
• Package version: flutter_stripe: ^10.1.1 flutter_stripe_web: ^5.1.0
• Flutter version: Flutter 3.19.2 • channel stable

Additional context Even on normal Chrome browser still it didn't launch, however, the Google Pay button on top of this stripe docs page works as expected on the same Chrome browser which means Google Pay is setup correctly in the device.

Sample Code

final options = PlatformPayWebPaymentRequestCreateOptions(
  country: 'JP',
  currency: 'jpy',
  total: PlatformPayWebPaymentItem(amount: 1000, label: "Total Amount"),
  disableWallets: [PlatformPayWebWalletType.link],
);

// Widget
if (isPlatformPaySupported)
  CustomPlatformPayButton(
    onPressed: handlePayment,
  )

Future<void> handlePayment() async {
  await stripe.createPlatformPayPaymentMethod(
    params: PlatformPayPaymentMethodParamsWeb(
      options: options,
    ),
  );
}
