What is Flutter Textfield Hint Text?

Flutter textfield hint text is as the name suggests, it shows a hint to the user about the input that the user should input in that Flutter textfield. It is really a good practice to use Flutter textfield hint text in a Flutter textfield because the user can have a better idea of what he/she should input in that particular Flutter textfield.

Flutter textfield hint text is visible when the Flutter textfield is empty and disappears when the user starts inputting and reappears when the Flutter textfield is empty again. It is shown in the same place where the inputted text is shown in the Flutter textfield. Let’s now understand it using a proper and easy Flutter example code.

Custom Flutter Textfield Hint Text

By default, our Flutter textfield won’t show any hint text. So in order to customize and show hint text in Flutter textfield, we have to use the decoration constructor of the Flutter textfield. Passing the input decoration class and using the hint text constructor of the input decoration class. Using this hint text constructor, we can now specify our own hint text.

This hint text constructor only takes a string, means only a text can be inputted in it. Let’s now implement it using Flutter code. See the below code for this:

TextField(
        decoration: InputDecoration(
              hintText: 'This is hint text',
                    ),
                  )

As you can see in the above code that I have used the hint text constructor and passed it a string. In the above image, you can see that the Flutter textfield hint text is successfully implemented in our Flutter textfield.

You can see the default color of Flutter textfield hint text, if you want to know how to change the Flutter textfield hint text color then click here.

Congrats, now you have a complete idea of how hint text works and how to change and customize Flutter textfield hint text in Flutter textfield.

I have prepared a beautiful Flutter textfield design for you in which Flutter textfield hint text is also implemented. Hope you will like it. The source code for this custom Flutter textfield is given in the next section.
