Decode Row & Column
An in-depth look at the Row and Column widget
A Flutter app’s user interface is made up primarily of what are called Widgets. Nothing but Widgets. Some you can see; some you can’t. This article is going to address two you can’t see, but are very important to the user interface. The Row widget and the Column widget.
You can’t readily see them rendered on the screen without Flutter highlighting their borders while debugging for example. However, in most cases, you can readily see their ‘children.’ Their children are, in fact, a List of other Widgets.
Row and Column widgets are used to align their children horizontally or vertically respectively, and to dictate how much space their children should occupy. If you only have one child widget to display, it’s suggested to use an Align widget or a Center widget instead to position and display it. The Row and Column widget are very much alike as you see below.
You can see both classes utilize the same list of named parameters and default values. Further, both use the same-named parameter to accept their List of Widgets. It’s called, children.
