Handling Software and Hardware Back Buttons in MAUI Shell

The back button can be software-based (in-app button) or hardware-based (OS back key). In MAUI Shell mode, these two types of back buttons are handled differently.

Handling software button
In the page, bind an event handler to the back button. In this case, the hardware back button will still navigate to the previous page.

<Shell.BackButtonBehavior> <BackButtonBehavior Command="{Binding ButtonCommand}"/> </Shell.BackButtonBehavior>

Handling hardware button
The hardware back button requires overriding the OnBackButtonPressed method in the page’s .cs file.
