In this blog, we will be going to learn about BackDrop Filter In Flutter and see how they work help us to improvise the user interface(UI) of the Flutter application.
Backdrop Filter is a widget that paints the existing container and then paints the child widget of it.The filter will be applied to all the areas within its parent or ancestor widget’s clip. If there’s no clip, the filter will be applied to the full screen.
It can be used to make a blur effect to the foreground of the widgets like images, text, containers, etc.

Code Snippet
We will use the following code snippets for using the same.

1 2 3 4 5 6 7 8 9 10 11 12 |
BackdropFilter( filter: ImageFilter.blur( sigmaX: 10.0, sigmaY: 10.0, ), child: Container( alignment: Alignment.center, width: 200.0, height: 200.0, child: const Text('Back Drop Filter'), ), ) |
NOTE:
—-> Backdrop Filter needs a child widget, which can be of any widget
—-> It needs a filter, which can vary with the requirements. For instance, we will blur the image so we are using the ImageFilter with blur effect
—-> The blend mode to use to apply the filtered background content onto the background surface
