Managing app permissions
Android and iOS systems have their own security policies involving user information or device hardware. The purpose of permission is to protect the privacy of a user. An app, whether native or not, must request permission to access user data, such as the camera, for example.
In iOS's recent versions, you must include the usage description in the ios/Runner/Info.plist file keys for the types of data the app needs to access, or it will crash. To access the camera, for example, it must include NSCameraUsageDescription.
