To change the background color of a PopupMenuButton in Flutter, you can wrap the PopupMenuButton widget inside a Container widget and set the color property of the Container to the desired background color.
Here’s an example:
<Container
color: Colors.blue, // Example background color
>
<PopupMenuButton<
// PopupMenuButton content here
></PopupMenuButton>
</Container>
In this example, we create a Container widget with a blue background color. Inside the Container, we have the PopupMenuButton widget which will display the popup menu when pressed.
You can replace “Colors.blue” with any other color you want. Flutter provides various color constants like Colors.red, Colors.green, etc. You can also use hexadecimal color codes or create your own custom colors by using the Color class.
