The Expanded
widget can be used inside a SingleChildScrollView
to provide flexible space for its child widget. The Expanded
widget takes up all remaining free space within its parent widget. This way, the child widget can grow or shrink depending on the available space.
Here’s an example of using Expanded
inside a SingleChildScrollView
:
SingleChildScrollView(
child: Column(
children: [
Container(
height: 100,
color: Colors.yellow,
),
Expanded(
child: Container(
color: Colors.green,
),
),
],
),
)
In this example, the SingleChildScrollView
contains a Column
widget with two children. The first child is a Container
with a fixed height of 100, and the second child is an Expanded
widget with a green Container
as its child. The Expanded
widget takes up all the remaining free space within the Column
widget, so that the SingleChildScrollView
can scroll the green Container
when the content inside it overflows.
By using Expanded
, you can control how your child widgets grow or shrink based on the available space, and make sure they take up all the space they need, no matter the screen size or orientation.
