Is there a way of disabling the history of the webview [the back button]?

From what i have read, this is an intended behaviour, if the user press the back button it should go back a page in the webview. However, there is some use cases [oauth] where the back button should close the flutter page [or the webview scaffold] and go back a previous screen in the app. This is to avoid going back to auth screens that only display json, or to avoid going back to the redirect url .

So... is there a way of disabling this behaviour?
