Flutter WillPopScope Widget - Android Back Button
The WillPopScope widget will allow you to control the back button of Android devices. The back button is not available on IOS devices, only for Android. The Will Pop Scope can be use to block or not the possibility of going back to the previous page. The widget can be useful if your user just sign-in and you don't want him to press the back button to go to the login back. If the use want to leave the application with the back button from Android , you could refresh the page with new content like some social media are now doing. In this case you could create a logic to ask the user to press two time the back button in order to leave. The Will Pop Scope Widget can be very useful in some scenarios.
