How to center column and row item in Flutter?

I have a small currency table. I didn't use grid. I used Column and rows. Problem is that items in rows is not showing in center as shown below in the Excel example. What widget do I have to use to make the items centered?

enter image description here

The Example codes:

return new Center(
  child: new Column(
    crossAxisAlignment: CrossAxisAlignment.center,
    children: <Widget>[
      new Row(
        mainAxisAlignment: MainAxisAlignment.center,
        children: <Widget>[
          new Padding(
            padding: const EdgeInsets.fromLTRB(15.0, 5.0, 15.0, 5.0),
            child: new Icon(
              Icons.crop_rotate,
              color: Colors.white,
            ),
          ),
          new Padding(
            padding: const EdgeInsets.fromLTRB(15.0, 5.0, 15.0, 5.0),
            child: new Text("STG", style: mainHeadTextStyle),
          ),
          new Padding(
            padding: const EdgeInsets.fromLTRB(15.0, 5.0, 15.0, 5.0),
            child: new Text("EUR", style: mainHeadTextStyle),
          ),
          new Padding(
            padding: const EdgeInsets.fromLTRB(15.0, 5.0, 15.0, 5.0),
            child: new Text("USD", style: mainHeadTextStyle),
          ),
        ],
      ),
      new Row(
        mainAxisAlignment: MainAxisAlignment.center,
        children: <Widget>[
....
....
....
Solution

  • If you want the whole table to be Centered, use the mainAxisAlignment property of Column.

    Column

    mainAxisAlignment: MainAxisAlignment.center //Center Column contents vertically,
crossAxisAlignment: CrossAxisAlignment.center //Center Column contents horizontally,

    Row

    mainAxisAlignment: MainAxisAlignment.center //Center Row contents horizontally,
crossAxisAlignment: CrossAxisAlignment.center //Center Row contents vertically,
