Flutter Newbie - Using ListView in a column/row layout

This shouldn't be a problem if you use standard flutter layouts. All you need is a Row, a ListView and your View for the content.

Here is some sample code that gives you this

Row(
  children: <Widget>[
    Expanded(
      flex: 1, //with this you can handle the width
      child: ListView(
        children: List.generate(
          5,
          (index) => Container(
            height: 200,
            color: Colors.red[100 + index * 100],
          ),
        ),
      ),
    ),
    Expanded(
      flex: 1,
      child: Container(
        color: Colors.green,
      ),
    )
  ],
);

Use the class Row to divide the screen in two under your header vertically.

Multiple rows in body of flutter application

Also, take a look at expand widget: https://api.flutter.dev/flutter/widgets/Expanded-class.html

Very similar example to what you are trying to do: Divide screen into 4 different parts evenly

Pseudocode:

Row(
  crossAxisAlignment: CrossAxisAlignment.stretch,
  children: <Widget>[
    Expanded(
      child: Column(
        crossAxisAlignment: CrossAxisAlignment.stretch,
        children: <Widget>[
          Expanded(
            child: Container(
              color: Colors.red,
            ),
          ),
          Expanded(
            child: Container(
              color: Colors.yellow,
            ),
          ),
        ],
      ),
    ),
  ],
);

The issue I couldn't solve was having a ListView widget with more items than there was space on the page. This is no problem until you try to build this into some kind of layout, where you have to give a container a size. I want the page to be responsive so setting a fixed size is not an opption.

The solution was to find the size of the viewport using MediaQuery and using the result to set the height of a Container widget.

Here's my code:

  Widget build(BuildContext context) {
return Scaffold(
  body: SafeArea(
    child: Column(
      crossAxisAlignment: CrossAxisAlignment.stretch,
      children: <Widget>[
        //Header Container
        Container(
          height: 80.0,
          padding: const EdgeInsets.all(8.0),
          color: Colors.blue,
          alignment: Alignment.center,
          child:
          TextField(
            decoration: InputDecoration(hintText: "Enter Text Here"),
          ),
        ),
        Row(
          crossAxisAlignment: CrossAxisAlignment.start,
          children: [
            //Body Container
            Expanded(
              flex: 2,
              child: SingleChildScrollView(
                padding: const EdgeInsets.all(10.0),
                child: Column(
                  children: <Widget>[
                    Container(
                      height: MediaQuery.of(context).size.height-100.0,
                      alignment: Alignment.center,
                      child: ListView.builder(
                        itemBuilder: (context, index){
                          return Card(
                            child: Padding(
                              padding: const EdgeInsets.all(5.0),
                              child: Column(
                                crossAxisAlignment: CrossAxisAlignment.start,
                                children: <Widget>[
                                  Text(_students[index].firstName + ' ' + _students[index].lastName),
                                ],
                              ),
                            ),
                          );
                        },
                        itemCount: _students.length,
                      ),
                    ),
                  ],
                ),
              ),
            ),
            Expanded(
              flex: 3,
              child: Padding(
                padding: const EdgeInsets.all(10.0),
                child: Container(
                    color: Colors.green,
                    alignment: Alignment.topLeft,
                    child: Text('Right')
                ),
              ),
            ),
          ],
        ),
      ],
    ),
  ),
);

} }
