How to make flutter card auto adjust its height depend on content


In the project, I'm using images and text inside the flutter card, but the card returns a fixed height. and then I also tried just using a card with an empty value, but it still returns a fixed height. what should I do to make the height of the card auto adjust with content?


    @override
    Widget build(BuildContext context) {
    final title = 'Food Recipes';
    return MaterialApp(
      title: title,
      home: Scaffold(
        appBar: AppBar(
          title: Text(title),
        ),
        body: GridView.builder(
            itemCount: _listViewData.length,
            gridDelegate:
                SliverGridDelegateWithFixedCrossAxisCount(crossAxisCount: 2),
            itemBuilder: (context, index) {
              return Card(
                margin: const EdgeInsets.all(10.0),
                child: Column(
                  crossAxisAlignment: CrossAxisAlignment.start,
                  children: [
                    AspectRatio(
                      aspectRatio: 18.0 / 13.0,
                      child: Image.network(
                        _listViewDataImage[index],
                        fit: BoxFit.fill,
                      ),
                    ),
                    Padding(
                      padding: EdgeInsets.fromLTRB(16.0, 12.0, 16.0, 8.0),
                      child: Column(
                        crossAxisAlignment: CrossAxisAlignment.start,
                        children: [
                          Text(
                            _listViewData[index],
                            textAlign: TextAlign.center,
                          ),
                        ],
                      ),
                    ),
                  ],
                ),
              );
            }),
      ),
    );
  }

Solution

  • The problem comes from SliverGridDelegateWithFixedCrossAxisCount:

    Creates grid layouts with a fixed number of tiles in the cross axis
    This delegate creates grids with equally sized and spaced tiles.

    I recommend you to use flutter_staggered_grid_view: and to give up to AspectRatio widget. More about tiles here.

    body: StaggeredGridView.countBuilder(
       crossAxisCount: 2,
       itemCount: 6,
       itemBuilder: (BuildContext context, int index) => 
         Card(
           margin: const EdgeInsets.all(10.0),
           child: Container(
             child: Column(
               crossAxisAlignment: CrossAxisAlignment.start,
               children: [
                Image.network('https://upload.wikimedia.org/wikipedia/commons/6/66/An_up-close_picture_of_a_curious_male_domestic_shorthair_tabby_cat.jpg',
                  fit: BoxFit.fill,
                ),
                Padding(
                  padding: EdgeInsets.fromLTRB(16.0, 12.0, 16.0, 8.0),
                  child: Column(
                    crossAxisAlignment: CrossAxisAlignment.start,
                    children: [
                      Text("Cat",textAlign: TextAlign.center),
                    ],
                ),
             )],
           ),
         )
       ),
       staggeredTileBuilder: (int index) =>
         StaggeredTile.fit(1),
    )
