Which product are you integrating?
mobile app using flutter
I mean our product.
Can you share us the document that you are looking at?
결제위젯 Flutter SDK(Version 1) | 토스페이먼츠 개발자...
결제위젯 Flutter SDK를 추가하고 메서드를 사용하는 방법을 알아봅니다.
You can just follow the guide? do you have any issue?
I can't find the guide to add a credit card
You just add the payment widget, it includes a credit card method.
But does it save the credit card to the user's account?
and then add the payment widget. I call the API /v1/brandpay/payments/methods/, does it show the newly added credit card in the payment widget?
If so you need to integrate brandpay with payment widget.

and to do that, you need to make a contract with us for a brandpay
1 . How can we determine which card (the default one) is selected for payment when there are multiple saved cards? Is it based on the selectedMethodId field?: https://docs.tosspayments.com/reference/brandpay#secretkey%EB%A1%9C-%EA%B2%B0%EC%A0%9C%EC%88%98%EB%8B%A8-%EC%A1%B0%ED%9A%8C
2. Is there a way to automatically retrieve the selected payment card information?
@Kimoon Lee
Are you only planning to use Brand Pay, or will you be integrating other payment methods as well? I can guide you based on that.
I’m running a WebView that loads an HTML file in Flutter, and I get the error: "null is not an object (evaluating 'history.state.tosspayments')".
Does this mean I must host the file on a real server, or is there another way to fix it?
Are you working for Korea Company?
I want to clearly understand which payment methods and products you need to integrate, so I can provide you with the right guidance.
1. yes
2. i use brandpay : https://docs.tosspayments.com/sdk/v2/js#brandpayaddpaymentmethod
I want to add a card from any bank, but currently I only see the method brandpay.addPaymentMethod(), which only works in JavaScript (browser).
I'm developing a Flutter app, so I tried using a inappWebView to load the HTML file that uses this JavaScript.
However, I encountered this error:
"null is not an object (evaluating 'history.state.tosspayments')"
Is there any way to make this work in Flutter? Or do I have to host the HTML file on a real server for it to work?

ok now i understand the problem.
I'll summarize and let you know.
First, is it correct that we should look for the UI we provide like this?
no it like
what is the UI for selecting the card?
no i can add to card.It seems I’ve managed to make it work, but there’s one remaining issue: when I open the WebView, how can I detect when the user presses the back button so that I can close the WebView?
What method you called to open this window?
