body: <p>I'm trying to add a gridview that has 2 columns and 3 rows. My problem is that when I try to add it to my Row it makes the whole page disappear. Here is my code</p>
  
  <pre><code>class HomePage extends StatelessWidget{
    @override
    Widget build(BuildContext context) {
      return Scaffold(
        appBar: new AppBar(
          elevation: 0.5,
          title: Text("Home", style: TextStyle(fontSize: 15, color: Colors.black45)),
          centerTitle: true,
          backgroundColor: Colors.white,
        ),
        body: SingleChildScrollView(
          child: Column(
            children: &lt;Widget&gt;[
              new Container(
                margin: const EdgeInsets.all(25),
                child: Text("Shop Category", style: new TextStyle(fontSize: 18, color: Colors.black, fontFamily: 'Raleway'),textAlign: TextAlign.left,),
              ),
              new GridView.count(
                primary: true,
                crossAxisCount: 2,
                children: &lt;Widget&gt;[
                  new Image.asset('assets/images/meat.jpg')
                ],
              )
            ],
