Hi, I am using flutter.
Within my flutter app, I have a WebView, and I am already rendering the PayPal buttons in it successfully :).
Find out more about the plugin I am using here: webview_flutter
The plugin uses WKWebView for iOS, and WebView for Android.
Please also check out my StackOverflow question I have asked here - it also contains screenshots:

It seems that the PayPal secure checkout fails on the last step of subscriptions.
All I see after pressing "Agree and Subscribe" is a "Processing" screen on iOS, and a bank page on Android.
This occurs right before the checkout finishes and calls "onApprove" - however - "onApprove" is never called!
Any assistance will be greatly appreciated!
