Flutter Staggered Grid View with different column

Flutter Staggered grid view :

Flutter Staggered grid view supports multiple columns with different row sizes.
In this blog, we will look to design a page with the different column count at the different row.

Read more about Flutter app development from mobikul.

Different Column Count At Different Row

StaggeredTileBuilder is used to create different no of the column in row and height of each tile.

There are three types of staggered tile, StaggeredTile.count , StaggeredTile.fit StaggeredTile.extent .

We will use StaggeredTile.extent(this.crossAxisCellCount, this.mainAxisExtent).

Where crossAxisCellCount is the number of column in a row and mainAxisExtent is the height of row item/tile.

Here, we will show the 1,2,3 column count on different rows.

Calculation of crossAxisCellCount

Let’s calculate crossAxisCellCount

SingleColumn crossAxisCellCount = 1*2*3=6/1 =6

TwoColumnGrid crossAxisCellCount = 1*2*3=6/2 =3

ThreeColumnGrid crossAxisCellCount = 1*2*3=6/3 =2

  staggeredTileBuilder: (int index) {
          if (listData[index].itemViewType == "TwoColumnGrid") {
            return new StaggeredTile.extent(
                3, (1 / 2) * MediaQuery.of(context).size.width);
          } else if (listData[index].itemViewType == "ThreeColumnGrid") {
            return new StaggeredTile.extent(
                2, (1 / 3) * MediaQuery.of(context).size.width);
          } else {
            return new StaggeredTile.extent(
                6, (1 / 2) * MediaQuery.of(context).size.width);
          }
        });

staggeredTileBuilder: (int index) {

if (listData[index].itemViewType == "TwoColumnGrid") {

return new StaggeredTile.extent(

3, (1 / 2) * MediaQuery.of(context).size.width);

} else if (listData[index].itemViewType == "ThreeColumnGrid") {

return new StaggeredTile.extent(

2, (1 / 3) * MediaQuery.of(context).size.width);

} else {

return new StaggeredTile.extent(

6, (1 / 2) * MediaQuery.of(context).size.width);

}

});

We will get the result as attached image

Staggered grid view example:

Let’s check the complete code.

class _HomePageState extends State<MyHomePage> {
  List<HomePageItems> listData = [];

  @override
  void initState() {
    super.initState();
    listData.add(HomePageItems(itemViewType: "SingleColumn"));
    listData.add(HomePageItems(itemViewType: "TwoColumnGrid"));
    listData.add(HomePageItems(itemViewType: "TwoColumnGrid"));
    listData.add(HomePageItems(itemViewType: "TwoColumnGrid"));
    listData.add(HomePageItems(itemViewType: "TwoColumnGrid"));
    listData.add(HomePageItems(itemViewType: "ThreeColumnGrid"));
    listData.add(HomePageItems(itemViewType: "ThreeColumnGrid"));
    listData.add(HomePageItems(itemViewType: "ThreeColumnGrid"));
    listData.add(HomePageItems(itemViewType: "ThreeColumnGrid"));
    listData.add(HomePageItems(itemViewType: "ThreeColumnGrid"));
    listData.add(HomePageItems(itemViewType: "ThreeColumnGrid"));
  }

  @override
  Widget build(BuildContext context) {
    return StaggeredGridView.countBuilder(
        crossAxisCount: 6,
        shrinkWrap: true,
        itemCount: listData.length,
        itemBuilder: (BuildContext context, int index) {
          switch (listData[index].itemViewType) {
            case 'TwoColumnGrid':
              {
                return Container(
                  color: Colors.blue,
                  margin: EdgeInsets.all(4),
                );
              }
              break;
            case 'ThreeColumnGrid':
              {
                return Container(
                  color: Colors.yellow,
                  margin: EdgeInsets.all(4),
                );
              }
              break;

            default:
              {
                return Container(
                  color: Colors.red,
                  margin: EdgeInsets.all(4),
                );
              }
              break;
          }
        },
        staggeredTileBuilder: (int index) {
          if (listData[index].itemViewType == "TwoColumnGrid") {
            return new StaggeredTile.extent(
                3, (1 / 2) * MediaQuery.of(context).size.width);
          } else if (listData[index].itemViewType == "ThreeColumnGrid") {
            return new StaggeredTile.extent(
                2, (1 / 3) * MediaQuery.of(context).size.width);
          } else {
            return new StaggeredTile.extent(
                6, (1 / 2) * MediaQuery.of(context).size.width);
          }
        });
  }
}

class _HomePageState extends State<MyHomePage> {

List<HomePageItems> listData = [];

@override

void initState() {

super.initState();

listData.add(HomePageItems(itemViewType: "SingleColumn"));

listData.add(HomePageItems(itemViewType: "TwoColumnGrid"));

listData.add(HomePageItems(itemViewType: "ThreeColumnGrid"));

}

@override

Widget build(BuildContext context) {

return StaggeredGridView.countBuilder(

crossAxisCount: 6,

shrinkWrap: true,

itemCount: listData.length,

itemBuilder: (BuildContext context, int index) {

switch (listData[index].itemViewType) {

case 'TwoColumnGrid':

{

return Container(

color: Colors.blue,

margin: EdgeInsets.all(4),

);

}

break;

case 'ThreeColumnGrid':

{

return Container(

color: Colors.yellow,

margin: EdgeInsets.all(4),

);

}

break;

default:

{

return Container(

color: Colors.red,

margin: EdgeInsets.all(4),

);

}

break;

}

staggeredTileBuilder: (int index) {

if (listData[index].itemViewType == "TwoColumnGrid") {

return new StaggeredTile.extent(

3, (1 / 2) * MediaQuery.of(context).size.width);

} else if (listData[index].itemViewType == "ThreeColumnGrid") {

return new StaggeredTile.extent(

2, (1 / 3) * MediaQuery.of(context).size.width);

} else {

return new StaggeredTile.extent(

6, (1 / 2) * MediaQuery.of(context).size.width);

}

});

}

I hope this blog will help to make the different number of columns in different rows.

Happy Learning 🙂
