Column explained for Android Developers

To cause a child to expand to fill the available vertical space, wrap the child in an Expanded widget. The Column widget does not scroll and it is considered an error to have more children in a Column than will fit in the available room. If you have a line of widgets and want them to be able to scroll if there is insufficient room, consider using a ListView.

Example Code

Here is an example of how to use Column:

const Column(
  children: [
    Text('Deliver features faster'),
    Text('Craft beautiful UIs'),
    Expanded(
      child: FittedBox(
        child: FlutterLogo(),
      ),
    ),
  ],
)

Column Remarks

The Column widget is essential for creating vertical layouts in Flutter, but care must be taken to manage its constraints properly.
