How can show grid view with other view in single page #flutter

Question

How to add grid view and other view in same page?
I try with listview but it is showing error

I/flutter (10293): Another exception was thrown: 'package:flutter/src/rendering/sliver_multi_box_adaptor.dart': Failed assertion: line 461 pos 12: 'child.hasSize': is not true. I/flutter (10293): Another exception was thrown: NoSuchMethodError: The getter 'scrollOffsetCorrection' was called on null. I/flutter (10293): Another exception was thrown: NoSuchMethodError: The method 'debugAssertIsValid' was called on null. I/flutter (10293): Another exception was thrown: NoSuchMethodError: The getter 'visible' was called on null

  body:ListView(
      children: <Widget>[
        Text("checking"),
        Container(
        child: GridView.count(
          crossAxisCount: 3,
          childAspectRatio: .6,
          children: _list.map((p) => ProductManagment(p)).toList(),
        ),
      ) 
      ],
    )

Another attempt

  body:ListView(
      children: <Widget>[
        Text("checking"),
         GridView.count(
          crossAxisCount: 3,
          childAspectRatio: .6,
          children: _list.map((p) => ProductManagment(p)).toList(),
        ) 
      ],
    )

again error

I think you should just set height of the Container or warp it by Expanded widget. And tell what happen?. Might be size is missing thats way error occurred.

EDITED :

 body:ListView(
      children: <Widget>[
        Text("checking"),
        Container(
        height: 300.0
        child: GridView.count(
          crossAxisCount: 3,
          childAspectRatio: .6,
          children: _list.map((p) => ProductManagment(p)).toList(),
        ),
      ) 
      ],
    )

Set height: 300.0 in container. (You can set height/width as per your requirement or try with Expanded widget)
