In this tutorial, we’ll learn how to easily change Flutter textformfield suffix icon color by using a proper practical Flutter example code.
Introduction: Flutter Textformfield Suffix Icon Color
Suffix icon comes on the right side of Flutter textformfield widget. Let’s first see its default color, then we’ll customize it using a practical Flutter example code.
Default Color: Suffix Icon
In order to see that, we’ve created a simple Flutter textformfield widget. We’ve passed a Flutter icon widget to the suffix icon constructor of input decoration class.
We also have wrapped this textformfield with a Flutter padding widget to create a horizontal distance between textformfield and screen borders(available in the complete source code in the end). See below code:
TextFormField( decoration: InputDecoration( suffixIcon: Icon( Icons.visibility, ), ))
Change Flutter Textformfield Suffix Icon Color
We can see in the above code that Flutter icon widget is passed to suffix icon constructor of input decoration class. We’ll be using color constructor of the same icon widget to change the color of suffix icon. This color constructor takes a color. For demonstration, we’ve passed a blue color to it. See below code:
suffixIcon: Icon( Icons.visibility, color: Colors.blue, )
As you can see in the above image that color of suffix icon is successfully customized.
So this is how you can easily change Flutter textformfield suffix icon color.
Feel free to ask if you still have any questions regarding the customization of suffix icon color in textformfield. I’ll be more than happy to answer all your questions.
