Describe the bug
Calling collectBankAccountToken fails due to missing params parameter when calling the Method Channel. An Invalid Parameters Exception is thrown.

To Reproduce
Steps to reproduce the behavior:

1. Get a financial connections session client secret with a secret key.
2. Pass that client secret to the collectBankAccountToken method as a parameter. Passing the params parameter is optional, but the failures occurs whether it's present or not.
3. Observe a failure with exception PlatformException with the following stack trace:

#0      JSONMethodCodec.decodeEnvelope (package:flutter/src/services/message_codecs.dart:168:7)
#1      MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:370:18)
<asynchronous suspension>
#2      MethodChannel.invokeMapMethod (package:flutter/src/services/platform_channel.dart:570:43)
<asynchronous suspension>
#3      MethodChannelStripe.collectBankAccountToken (package:stripe_platform_interface/src/method_channel_stripe.dart:559:20)
<asynchronous suspension>
 ... 

Expected behavior
The method is called correctly and the modal sheet that allows user to connect a bank is show.
