collectBankAccount returns PlatformException

[chilimsv]

Describe the bug
Calling collectBankAccount on both iOS and Android returns PlatformException(Invalid Params, , , null)

To Reproduce
Call this function

 const billingDetails = BillingDetails(
        name: 'Flutter Stipe',
        email: 'email@stripe.com',
        phone: '+48888000888',
        address: Address(
          city: 'Houston',
          country: 'US',
          line1: '1459  Circle Drive',
          line2: 'S',
          state: 'Texas',
          postalCode: '77063',
        ),
      );
      await Stripe.instance.collectBankAccount(
        isPaymentIntent: true,
        clientSecret: paymentInfo.clientSecret,
        params: const CollectBankAccountParams(
          paymentMethodType: PaymentMethodType.USBankAccount,
          billingDetails: billingDetails,
        ),
      );

This is returned:

[   +1 ms] flutter: PlatformException(Invalid Params, , , null)
[        ] flutter: 
           #0      JSONMethodCodec.decodeEnvelope (package:flutter/src/services/message_codecs.dart:171:7)

           #4      Stripe.collectBankAccount (package:flutter_stripe/src/stripe.dart:583:12)
           <asynchronous suspension>

Expected behavior
I expect a modal to show up to collect bank details after calling this method with required parameters

Package version: flutter_stripe: 9.5.0+1
Flutter version: stable, 3.13.0

Additional context
Is this the wrong usage or a bug? Every parameter is filled

No luck. Decided to collect the bank details on our client side as a workaround

Hey, any update on this? collectBankAccount still doesn't work.

I've found 2 problems:

1. Flutter plugin send
   'isPaymentIntent':isPaymentIntent and ios side use wrong key
   let isPaymentIntent = arguments["intentType"] as? Bool,

2. Flutter plugin send as params CollectBankAccountParams parsed to json and both ios and android side try to extract this by paymentMethodData which is not in that model.

What with this draft PR?
