Flutter table structure

Question

I want to get this structure:

-----------------------------------------------------------------------------------
item 1                                 item 2
item 3                                 item 4
-----------------------------------------------------------------------------------

Basically I'd need to have a Table with 2 columns with 2 rows in each column, but this is the effect I get:

Here is my code:

new Container(
          decoration: new BoxDecoration(color: Colors.grey),
          child: new Row(
            children: <Widget>[

              new Column(
                children: <Widget>[
                  new Container(
                    decoration: new BoxDecoration(color: Colors.red),
                    child: new Text("item 1"),
                  ),
                  new Container(
                    decoration: new BoxDecoration(color: Colors.amber),
                    child: new Text("item 3"),
                  ),
                ],
              ),

              new Column(
                children: <Widget>[
                  new Container(
                    decoration: new BoxDecoration(color: Colors.green),
                    child: new Text("item 2"),
                  ),
                  new Container(
                    decoration: new BoxDecoration(color: Colors.teal),
                    child: new Text("item 4"),
                  )
                ],
              )

            ],
          ),
        )

I want each column to take half of the width space available. On Android I'd use the weight property and that's it.

using flex(by default it's 1) you can separate the two columns and then use the crossAxisAlignmentto align them items in the beginning :

  new Container(
    decoration: new BoxDecoration(color: Colors.grey),
    child: new Row(
      children: <Widget>[
        Expanded(
          child: new Column(
            crossAxisAlignment: CrossAxisAlignment.start,
            children: <Widget>[
              new Container(
                decoration: new BoxDecoration(color: Colors.red),
                child: new Text("item 1"),
              ),
              new Container(
                decoration: new BoxDecoration(color: Colors.amber),
                child: new Text("item 3"),
              ),
            ],
          ),
        ),
        Expanded(
          child: new Column(
            crossAxisAlignment: CrossAxisAlignment.start,
            children: <Widget>[
              new Container(
                decoration: new BoxDecoration(color: Colors.green),
                child: new Text("item 2"),
              ),
              new Container(
                decoration: new BoxDecoration(color: Colors.teal),
                child: new Text("item 4"),
              )
            ],
          ),
        )
      ],
    ),
  )

Thanks a lot, that's exactly what I needed. I really appreciate your help :) – Formulaic

i am really happy to hear that – Lightness

why flex: 2 on both Expanded ? They negate each others – Tektite

sorry @RémiRousselet will update my answer i didn't notice that – Lightness

How you can manage text lines it should be equal in the left and right columns. – Chemo

Answer 2

I would suggest using the Table Widget for consistency and ease as nested rows and columns can get a little messy and far indented.

https://docs.flutter.io/flutter/widgets/Table-class.html

   ...
Table(children: [
  TableRow(children: [
    Text("item 1"),
    Text("item 2"),
  ]),
  TableRow(children:[
    Text("item 3"),
    Text("item 4"),
  ]),
]);

To create a table with Header & scroll.

return Container(
      child: SingleChildScrollView(
        scrollDirection: Axis.horizontal,
        child: Column(
          children: <Widget>[
            headerRow(), /* Header Row */
            dataRow(), /* Row 1 Data */
            dataRow(), /* Row 2 Data */
            Column(
              children: /* Add row cell data dynamically */,
            ),
          ],
        ),
      ),
    );

headerRow(List<dynamic> titleRowData) {
    return Container(
      height: ScreenUtil().setHeight(100),
      child: Row(
        children: /* Add header cell data dynamically */,
      ),
      decoration: BoxDecoration(
        borderRadius: BorderRadius.only(
          topLeft: Radius.circular(10),
          topRight: Radius.circular(10),
        ),
        gradient: LinearGradient(
          begin: Alignment.topCenter,
          end: Alignment.bottomCenter,
          stops: [0, 1],
          colors: [skyBlueColor, indigoColor],
        ),
      ),
    );
  }
