Back Button didn't show up in new Page of Flutter-CodePudding

i make a new page of flutter but in my case the back button didn't show up automatically. I watch many tutorial and they always have the back button automatically when they make a new page in flutter. anybody know how to solve this problem of mine?

CodePudding user response：

Use Navigator.push() instead of Navigator.pushAndRemoveUntil()

Add some sample of your code please. Meanwhile you can do this

           return Scaffold(
           appBar: AppBar(
          leading: GestureDetector(
             onPress:(){
          Navigator.of(context).pop();
         }          ,
      child: Icon(
             Icons.arrow_back,//add color of your choice
          ), 
        ),
          title: const Text(
            "Where to?",
          ),
        ),
);
