问题 I'm updating an app that was compiled on Xcode 10 and running fine up through iOS 13. I wanted to make some changes so recompiled on Xcode 11 and now have a problem with the barTintColor. If 'Large Titles' is set to 'Always' my custom barTintColor is not applied -- I just get the default gray. If 'Large Titles' is set to 'Never', my custom barTintColor is applied as expected. If 'Large Titles' is set to 'Automatic', the NavBar is default gray when Large Titles are shown and my custom color

问题 When using prefersLargeTitles for a UINavigationController 's UINavigationBar in iOS 11 , the nav bar increases height. The increase is from 44 to 96 on the iPhones I have checked, but I think those numbers can change per device (or at least we need to code as if they can). I want to programmatically find the 'extra' height - the height of the large titles area that is added beneath the traditional UINavigationBar when a large title is displayed. I can easily find the entire height of the bar

问题 I would like to make my Flutter app take up the entire screen in Android while still showing both the status bar and the navigation bar, with both of them transparent, to achieve the full screen look like in iOS. The status bar color can be easily changed, but right now I'm facing problems with getting the app to fill up the screen and making the navigation bar transparent at the same time. By default, the app is not drawn below the navigation bar at all (I've set the status bar color to be
