What is Icon Button?

According to flutter, An icon button is a picture printed on a Material widget that reacts to touches by filling with color(ink).

It is one of the most used Buttons in Flutter. It shows It if we press that icon it executes some programs.

This Icon Button has some properties. But there are two mandatory properties, icon, and onPressed. We must implement its icon. If the onPressed callback is null, it will not react when it is pressed.

You can find lots of icons and its name on the Material Design Icon website.

Create a Basic Icon Button

Step-1: Basic page layout:

So here we will create a basic icon button. First, we create our page body with a title. Now, in the body, we create a stateless widget. In this widget, we create a container. In this container, we will create a button.

Step-2: Create the Button:

In that container, we create an Icon Button. To align it in the center, we wrap it in the center widget. This button has two main properties, icon, and onPressed. So we put a Home icon. And we left the onPressed callback null. We use the notification icon. This is a default Icon Button.

IconButton(
              icon: Icon(Icons.notifications),
              onPressed: () {},
            ),

After knowing its properties, we will create different styled buttons.

We create a basic page layout that has an App bar and a bottom navigation bar. if you don’t know how to create a bottom navigation bar or want to customize the bottom navigation bar then click the link below.

Properties of Icon Button

There are many properties. But we learn some of them. Don’t worry, with these properties, we mentioned below, we can create and customize our buttons as we want.

Now we create some Icon buttons to understand how their properties work.

Example-1: Create a button with a Gradient background color

Container(
            height: 50,
            width: 50,
            decoration: BoxDecoration(
                borderRadius: BorderRadius.circular(50),
                gradient: LinearGradient(
                colors: [Colors.amber, Colors.red])),
            child: IconButton(
              alignment: Alignment.center,
              iconSize: 25,
              color: Colors.white,
              splashColor: Colors.amber,
              highlightColor: Colors.grey,
              mouseCursor: MouseCursor.uncontrolled,
              tooltip: "Icon Button",
              icon: Icon(Icons.notifications),
              onPressed: () {},
            ),
          ),

Here we create a customized Icon Button. At first, we wrap the button in a container. Then we define the container height and width. After that, we decorated the container. We add a gradient color and give it a border radius.

Now in the button Widget, we define its properties.

1. We define its alignment property. We align the icon center in the container.
2. Then we increase its size with iconSize. The default icon size is 24.0.
3. We use splashColor. So that it shows color when we pressed the button.
4. We don’t write any code in the onPressed property. We left it null.
5. Here we create a button with the gradient background color.

Example-2: Create a button with Gradient colored-Icon

Container(
            height: 50,
            width: 50,
            child: ShaderMask(
              shaderCallback: (Rect bounds) => RadialGradient(
                center: Alignment.topCenter,
                colors: [Colors.amber, Colors.red],
                tileMode: TileMode.mirror,
              ).createShader(bounds),
              child: IconButton(
                alignment: Alignment.center,
                icon: Icon(
                  Icons.home,
                  size: 40,
                  color: Colors.white,
                ),
                onPressed: () {},
              ),
            ),
          ),

Apply a color gradient to the icon

Now we will create an Icon Button with gradient Colored icon. Before we have done it, here we also created a button in a container widget. Thus we can’t directly color the icon with a gradient shade. So we use the shaderMask widget. In it, we can fill the icon with gradient shade. Then we create the Button as its child.

Now we create a Button with a gradient color.
