What is Flutter Textformfield Outline Border Color?

Flutter textformfield outline border color is as the name suggests, it is the color of the Flutter textformfield border, when we use outline border then it covers all the border sides of the textformfield. Don’t worry, I will now implement it using proper example so you can have a better idea of what outline border is and how can we change Flutter textformfield outline border color.

Default Flutter Textformfield Outline Border Color

Let’s see the default Flutter textformfield outline border color. For that we have to use the decoration constructor of the Flutter textformfield, then pass it input decoration class and by using the enabled and focused border constructors, we can pass the outline input border class. See the below code:

TextFormField(
           decoration: InputDecoration(
                  enabledBorder: OutlineInputBorder(),
                  focusedBorder: OutlineInputBorder(),
                ),
              )

Now let’s implement the customization of outline border color of Flutter textformfield. For that we have to use the same process mentioned above and after that we have to use the border side constructor of the outline input border class and pass it the border side class. Using the color constructor of the border class class, we can change the color of the outline border of Flutter textformfield. See the below code:

OutlineInputBorder(
            borderSide: BorderSide(color: Colors.green))
