Solved: Flutter align two items on extremes - one on the left and one on the right

Question

Asked by MistyD on May 16, 2018 (source).

I am trying to align two items at extremes one on the left and one on the right. I have one row that is aligned to the left and then a child of that row is aligned to the right. However it seems the child row is picking up the alignment property from its parent. This is my code

var SettingsRow = new Row(
            mainAxisAlignment: MainAxisAlignment.end,
            crossAxisAlignment: CrossAxisAlignment.center,
            mainAxisSize: MainAxisSize.max,
            children: <Widget>[
                Text("Right",softWrap: true,),
            ],
        );

        var nameRow = new Row(
            mainAxisAlignment: MainAxisAlignment.start,
            crossAxisAlignment: CrossAxisAlignment.center,
            mainAxisSize: MainAxisSize.max,
            children: <Widget>[
                Text("Left"),
                SettingsRow,
            ],
        );

as a result I get something like this

Left Right

What I would like is

Left      Right

Also there is enough space on the Row. My question is why is the child Row not exhibiting its MainAxisAlignment.end property ?

Answer

Question answered by Rémi R (source).

Use a single Row instead, with mainAxisAlignment: MainAxisAlignment.spaceBetween.

new Row(
  mainAxisAlignment: MainAxisAlignment.spaceBetween,
  children: [
    new Text("left"),
    new Text("right")
  ]
);

Or you can use Expanded

new Row(
  children: [
    new Text("left"),
    new Expanded(
      child: settingsRow,
    ),
  ],
);
