How do I remove the top padding for iOS?

Hi, I'm quite new to flutter and programming in general. I'm wondering how to remove the top padding that is present for iOS. I looked in scaffold.dart but I'm quite confused on which parameters to adjust. Ideally, I'd like my WebViews scaffold to fill into the safe area. I'd like the WebView to extend right to the top of the phone. Would like there to be no white area as shown in the photo.

Thanks!
