Unable to test Flutter app on iPhone due to certificate issue

I built a Flutter app using Android Studio. Works fine on iPhone simulator. When I go to test on my iPhone however by opening up workspace on Xcode and running it with my iPhone connected to my laptop, I get this error:

The certificate used to sign "Runner" has either expired or has been revoked. An updated certificate is required to sign and install the application.

I'm at a loss at what to do here. I am using a free apple developer account.

Any help appreciated!
