              ),
              onPressed: (){
                Navigator.of(context).pushNamed('/logingpage');
              },
              child: Padding(
                padding: const EdgeInsets.symmetric(vertical: 15.0,horizontal: 25.0),
                  child: Text(
                    "Log In",
                  style: GoogleFonts.questrial(
                  color: Colors.white,
                  fontSize: 25.0
                  ),
                ),
              ),
        ),

`
but the context claims that the context is undefined.
i appreciate it
