How to use StaggeredGridView inside Column in flutter?

Question

I have a code that is working fine without using StaggeredGridView.count() inside Column. Can anyone help me out ? I'm totally new in flutter!

import 'package:flutter/material.dart';
import 'package:http/http.dart';
import 'smooth_star_rating.dart';
import 'package:flutter_staggered_grid_view/flutter_staggered_grid_view.dart';

void main() => runApp(MaterialApp(
      theme: ThemeData(primaryColor: Colors.black),
      home: Home(),
    ));

class Home extends StatelessWidget {
  Container TopArtist(String imageVal, String heading, double count) {
    return Container(
      width: 200,
      child: Card(
        shape: RoundedRectangleBorder(
            borderRadius: BorderRadius.all(Radius.circular(15.0))),
        color: Color(0xFFf2630a),
        child: Wrap(
          children: [
            Padding(

Solution

You have to put Column inside a Material() widget and also add the very important properties shrinkWrap: true, and physics: NeverScrollableScrollPhysics(),

Full example below:

import 'package:flutter/material.dart';
import 'package:flutter_staggered_grid_view/flutter_staggered_grid_view.dart';

Future<List<String>> _getPictures() async {
  /// replace with your async query to your REST api.
  return [
    'https://apod.nasa.gov/apod/image/0708/hh49_spitzer_c29.jpg',
    'https://apod.nasa.gov/apod/image/1507/trifid_spitzerR1024.jpg',
    'https://apod.nasa.gov/apod/image/1409/rippledsky_dai_960.jpg'
  ];
}

class StaggeredInsideColumn extends StatefulWidget {
  const StaggeredInsideColumn({
    Key? key,
  }) : super(key: key);

  @override
  _StaggeredInsideColumnState createState() => _StaggeredInsideColumnState();
}

class _StaggeredInsideColumnState extends State<StaggeredInsideColumn> {
  late final Future<List<String>> _pictureUrlList;

  @override
  void initState() {
    super.initState();
    _pictureUrlList = _getPictures();
  }

  @override
  Widget build(BuildContext context) {
    return SingleChildScrollView(
        child: Material(
            child: Column(children: [
      Text('hello world'),

      /// ... your other column items

      FutureBuilder<List<String>>(
          future: _pictureUrlList,
          builder: (context, AsyncSnapshot<List<String>> snapshot) {
            if (snapshot.connectionState == ConnectionState.done &&
                snapshot.hasData) {
              List<String> pictures = snapshot.data!;
              return StaggeredGridView.countBuilder(
                shrinkWrap: true,
                physics: NeverScrollableScrollPhysics(),
                crossAxisCount: 3,
                itemCount: snapshot.data!.length,
                itemBuilder: (BuildContext context, int index) => Container(
                  child: Image.network(
                    pictures[index],
                    fit: BoxFit.fitWidth,
                  ),
                ),
                staggeredTileBuilder: (int index) {
                  int tileCount = index % 7 == 0 ? 2 : 1;
                  return StaggeredTile.count(tileCount, tileCount);
                },
                mainAxisSpacing: 8.0,
                crossAxisSpacing: 8.0,
              );
            } else
              return CircularProgressIndicator();
          })
    ])));
  }
}
