How to detect user has cancelled paymentRequestWithCardForm

When I am calling paymentRequestWithCardForm the library opens the form where you can add payment cards. This method return promise which gives me token etc when succesful. Here is an example:

try {
  const { tokenId } = await stripe.paymentRequestWithCardForm();
  // do stuff
} catch (error) {
  // show error message
}

The problem is that when user presses Cancel on the form the catch is fired. On iOS you get this response back:

From here I can use code -3 which means it was cancelled by user. But on Android when I press Cancel I get this response:

{
  "framesToPop": 1,
  "code": "AddCardDialogFragment"
}

So how I am suppose to know on Android when user has cancelled the modal? 😄 Or am I missing something?

I used the following workaround:

Add <string name="gettipsi_user_cancel_dialog" translatable="false">-3</string> to android string resources as this is the string tipsi-stripe returns in case of user cancel on android.

stripe.paymentRequestWithCardForm(options).then((token) => {
  // Success
}).catch((error) => {
  const cancelAction = '-3';
  if((isAndroid && error.message === cancelAction) || (isIos && error.code === cancelAction)) {
    // Cancelled by user
  }
});

@hannta Can this be closed then?
