I need to integrate Flutter with an already existing SSO for a client. I am using url_launcher to open up an external webpage in Flutter for them to sign on, however I cannot find a way to return data from that website to Flutter via url_launcher. I can't use HTML get/posts because it won't work for the SSO apparently since it uses SAML? Is there a way to circumvent this? I have access to a NodeJS server which I can use for this project, if any solution could be made around that.
Best regards,
Chai
