Maybe something like this:

 @override
 Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title)),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.start,
            children: <Widget>[
              Flexible(
                child: child: gridView(),
              ),
              Container(
               child: Padding(
                padding: const EdgeInsets.all(5),
                child: Column(
                  mainAxisAlignment: MainAxisAlignment.center,
                  children: <Widget>[
                    Text(
                      "Enter the Device Details",
                      style: TextStyle(
                        color: Colors.white,
                        fontSize: 30,
                        fontWeight: FontWeight.bold,
                      )
                    )
                  ]
                )
               )
              ),
            ],
          ),
        )
    );
  }
