I'm developing a Flutter app that works perfectly on iOS and Android phones. However, when I run it on an iPad (e.g., iPad Air 11-inch) using the iOS simulator, the app appears centered with black bars on the left and right sides, instead of expanding to fill the full screen.
You can change the project settings [Xcode] by setting TARGETED_DEVICE_FAMILY to iPhone, iPad in Build Settings,
or by going to the General tab → Supported Destinations → and adding iPad as a supported device.
