In Flutter, the Visibility Widget is used to show or hide a child/widget. By default, the visible property controls whether the child is included in the subtree or not; when it is not visible, the replacement child (typically a zero-sized box) is included instead.
So, In this tutorial, we will see a simple example Let's start
Step 1: Create a new Flutter Application.
Step 2: Declare a bool variable that will be used to change the visibility in your stateful widget. for example
bool isVisible = false;
Step 3: Now we can use Visibility widget in our app, simply use this widget where you want to hide/show other widget also it has different properties such as
visible
replacement
maintainState
maintainAnimation
maintainSemantics
maintainInteractivity
visible: property will have our bool variable
child: property will have the widget that is visible if the value is true
replacement: property will be the widget that is displayed when the child widget is hidden
for example:
Visibility(
visible: isVisible,
child: SizedBox(
height: 200,
width: 200,
child: Image.asset('assets/splashscreen.png'),
),
replacement: Container(
height: 200,
width: 300,
color: Colors.red,
),
)
