In my Widget which calls the ReaderWidget i have a logon page Button. When the user clicks this button, he is navigated to a logon oage. After Logging in the user can create a qr-code. But when he navigates back, i don't want to call the login page. Instead i want the user to go back to the Reader Widget page. So i use Navigator.popUntil(context, "QRCodeScanner"); . But then the ReaderWidget closes the camera connection. See log below:
