Overview
The cupertino_will_pop_scope package extends Flutter's Cupertino widgets by enabling onWillPop callbacks during page transitions on iOS-style navigation. It enhances user experience by providing visual feedback when a swipe-to-go-back gesture is rejected, ensuring smoother and more intuitive navigation. This package is particularly useful for apps that require custom confirmation logic before navigating back, such as form validation or unsaved changes. It integrates seamlessly with existing CupertinoPageScaffold and CupertinoPageRoute implementations.
