How to Get Glassmorphism Effect in Flutter

Last updated Nov 30, 2021

What is Glassmorphism?

Glassmorphism is a term used to describe UI design that emphasizes light or dark objects, placed on top of colorful backgrounds. A background blur is placed on the objects which allows the background to shine through – giving it the impression of frosted glass.

In today's tutorial, we will see you can get glassmorphism effect in Flutter 

Let's start

Step 1: Create a new Flutter Application.

Step 2: You can wrap your widget with Back Drop Filter and add an image filter but, this process is a bit complicated so, we will see an easy way all you have to do is add a line like this to your package's pubspec.yaml.

dependencies:
  glassmorphism: ^3.0.0

 

 

Step 3: Once installed you will get access to a widget called GlassmorphicContainer, it has various properties

  • width: used to control the width of the container.
  • height: used to control the height of the container.
    
  • borderRadius: used to change the border radius.
  • linearGradient: used to provide background gradient with different colors.
    child: which will hold all our widget that will have this effect.

we can add gradient like this for example

LinearGradient(colors: [

                        Colors.white.withOpacity(0.2),

                        Colors.white.withOpacity(0.05)

                      ], begin: Alignment.topLeft, end: Alignment.bottomRight),

 

this will have the most common white forsted glass effect.
