I have a subscription form online on a website. Now I am trying to build a mobile app with flutter. I want to give my app users the possibility to subscribe as well. But I don't want to do the form validation in the app, since it can change from time to time.
What I did is create a webview widget in flutter, this worked, untill the very last step. The last step for a subscription is pay for it. This can be done with a banking app on the phone, but when I click the link to the banking app from the webview, it throws an error:
net::ERR_UNKNOWN_URL_SCHEME
The link it's trying to reach is: intent://bankieren.ideal.ing.nl/..........
So the problem seems to me this intent... Is there a way I can make this intent work in the webview? If not, is there a way I can 'mirror' my web-form so I don't have to validate on 2 different locations (web and app)?
