I was able to override the back button onPressed behavior using WillPopScope. Now, whenever I press the device back button or the default AppBar back button, the code inside onWillPop runs as expected.

The problem now is that I want to have my own custom buttons to navigate backward, but Navigator.of(context).pop() doesn't check the WillPopScope as if it doesn't exist. I also tried Navigator.of(context).maybePop(), but I get the same behavior.

• Is there a way to simulate the system's back behavior or call it somehow?
• I know I can just call the same function that is called by onWillPop() manually upon pressing my custom back button, but I was eager to find a cleaner method, as in the future I could easily forget doing that and cause bugs.

In simple cases, when you need to intercept the Android back-button, you usually add WillPopScope to your widget tree. However, when developing stateful widgets that interact with the back button, it's more convenient to use the BackButtonInterceptor.

While using StateFullWidget, It is more convenient to use BackButtonInterceptor. Hope this will Helpful. For more Details Please check this: [1]: https://pub.dev/packages/back_button_interceptor
