Flutter positioning widgets in Column

Question

I am trying to set an image in the center of Column, and the Text at the bottom of the image, by wrapping Image and Text in the Column widget and placing it in the Center widget.

Unfortunately, it centers the Column and makes Image to be above the center of the screen.

How can I solve it?

My current code:

  @override
  Widget build(BuildContext context) {
    return Container(
      decoration: BoxDecoration(color: Theme.of(context).primaryColor),
      child: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            Image.asset(ImagePaths.newLogoLogin),
            Text(Strings.beALocal)
          ],
        ),
      ),
    );
  }

Answer 1

This can be achieved using the Expanded widget:

@override
Widget build(BuildContext context) {
  return Container(
    decoration: BoxDecoration(color: Theme.of(context).primaryColor),
    child: Column(
      children: [
        Spacer(),
        Image.asset(ImagePaths.newLogoLogin),
        Expanded(
          Column(
             children: [ Text(Strings.beALocal) ],
             mainAxisAlignment: MainAxisAlignment.start
          )
        )
      ],
    ),
  );
}

You could use a Stack with a Positioned Text widget inside it.

Full example:

void main() => runApp(App());

class App extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: Text("Test")),
        body: Stack(children: [Placeholder(), Test()]),
      ),
    );
  }
}

class Test extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Center(
      child: Stack(
        alignment: AlignmentDirectional.bottomCenter,
        overflow: Overflow.visible,
        children: <Widget>[
          Container(
            width: 150,
            height: 150,
            color: Colors.blue,
          ),
          Positioned(child: Text("Some text"), bottom: -25),
        ],
      ),
    );
  }
}
