did you add flutter_stripe_web to you dependencies? I cannot reproduce it on our example app which has identical code

dereking commented 1 month ago

Yes, I added flutter_stripe_web to my dependencies yet.

dereking commented 1 month ago

It looks like the issue is provoked by web hot reload after a added flutter_stripe_web . I restart flutter run -d chrome, It works. But i think I should test more on iOS and Android..

dereking commented 1 month ago

Latest found:

I found that flutter-stripe depends on stripe_platform_interface: ^11.1.1

But stripe_platform_interface dosn't support web... only support Android\iOS\Linux\macOS\Windows.

stripe_err

The source code caused error is : stripe_platform_interface-11.1.1/lib/src/method_channel_stripe.dart 672:33 create

class MethodChannelStripeFactory {
  const MethodChannelStripeFactory();

  StripePlatform create() => MethodChannelStripe(
        methodChannel: const MethodChannel(
          'flutter.stripe/payments',
          JSONMethodCodec(),
        ),
        platformIsIos: Platform.isIOS,   <--------cause error: DartError: Unsupported operation: Platform._operatingSystem
        platformIsAndroid: Platform.isAndroid,
      );
}

the problem is "Platform". We need to add web support in this method:

StripePlatform create() => MethodChannelStripe(
        methodChannel: const MethodChannel(
          'flutter.stripe/payments',
          JSONMethodCodec(),
        ),
        platformIsIos: !kIsWeb && Platform.isIOS,    
        platformIsAndroid:  !kIsWeb && Platform.isAndroid,
      );

Hope can help.
