Staggered Grid View unable to show data in 2 columns

I am very new at Dart so if this problem seems trivial or not required, I apologize!!

I want to implement Pinterest-style grid layout for my feed with only 2 columns. I am using the staggered_grid_layout and I tried implementing an answer from a stackoverflow question. Here is my code till now:

home.dart

SizedBox(
            height: 535,
            width: 180,
            child: new StaggeredGridView.countBuilder(
              crossAxisCount: 2,
              itemCount: 10,
              itemBuilder: (BuildContext context, int index) => Card(
                child: Column(
                  children: <Widget>[
                    Image.network(storiesList[index]),
                    Text("Some text"),
                  ],
                ),
              ),
              staggeredTileBuilder: (int index) =>
              new StaggeredTile.fit(2),
              mainAxisSpacing: 4.0,
              crossAxisSpacing: 4.0,
            ),
          )

link to full code

NOTE: I added the SizedBox() because I was getting a Vertical viewport was given unbounded height error, please recommend an alternative if that is not alright

Thank you!

CrossAxisCount is the number of "tiles" you want to divide the grid. StaggeredTile.fit(x) is the number of tiles you want to use for item[index]. So, if CrossAxisCount is 2, StaggeredTile should be fit(1), if you want 2 columns. You can even say CrossAxisCount is 8 and StaggeredTile.fit(4) for 2 columns, StaggeredTile.fit(2) for 4 columns... and so on. In this way you can change Columns number for each row depending on any condition placed for StaggeredTile.fit.

Thanks for update, Check out below code no need of StaggeredGridView instead use GridTile,

GridView.count(
          physics: const NeverScrollableScrollPhysics(),
          scrollDirection: Axis.vertical,
          shrinkWrap: true,
          crossAxisCount: 2,
          childAspectRatio: 1.0,              
          padding: const EdgeInsets.all(4.0),
          mainAxisSpacing: 4.0,
          crossAxisSpacing: 4.0,
          children: new List<Widget>.generate(3, (index) {
            return new GridTile(
              child: InkResponse(
                child: new Card(
                // color:Colors.white,
                child: new Center(
                  child: new Text('XYZ'),
                 ),
                ),
                enableFeedback: true,
                onTap: () => _onSelected(index, items[index].toString().substring(0,10)), // Whatever you want on tap
                ),
              );
          }),
        ),
