How To Change Flutter Dropdown Icon Color

Flutter dropdown icon color customization. In this post, I will be discussing and implementing how to change Flutter dropdown icon color in Flutter dropdown. I will be using an easy Flutter example code and a step by step explanation so you can have a better idea of how to change Flutter dropdown icon color. Let’s get right into implementing the customization of icon color in Flutter dropdown.

What is Flutter Dropdown Icon Color?

Flutter dropdown icon color is the color of icon of the Flutter dropdown. That icon is shown by default in the right side of the Flutter dropdown. Let’s now change the color of Flutter dropdown icon using a proper Flutter example code.

Default Flutter Dropdown Icon Color

Let’s see the default icon color of the Flutter dropdown. For that we have to implement a Flutter dropdown button widget, we have given it some flutter dropdown menu items and also we have used Flutter dropdown onchanged to show the selected item from the list in Flutter dropdown. See the below code:

DropdownButton(
            isExpanded: true,
            hint: Text('Select a category',
                style: TextStyle(fontSize: 15)),
            value: categoryValue,
            items: [
              DropdownMenuItem(
                  value: 'Sports',
                  child: Text('Sports',
                      style: TextStyle(fontSize: 15, color: Colors.black45))),
              DropdownMenuItem(
                  value: 'Tech',
                  child: Text('Tech',
                      style: TextStyle(fontSize: 15, color: Colors.black45))),
            ],
            onChanged: (val) {
              setState(() {
                categoryValue = val.toString();
              });
            }),

In the above image, you can see the default Flutter dropdown icon color in Flutter dropdown. The color of icon is grey. Let’s now see how we can change Flutter dropdown icon color.

Change Flutter Dropdown Icon Color

To change the Flutter dropdown icon color, we have to use the icon enabled color constructor of the Flutter dropdown button widget. It takes a color so we have passed it a blue color. See the below code:

iconEnabledColor: Colors.blue

You can see in the above image that the color of the Flutter dropdown icon is now changed.

So in this way you can change Flutter dropdown icon color in Flutter dropdown button widget. If you still have any doubts and questions about Flutter dropdown icon color customization then comment it. I would love to answer all your queries.
