Flutter is a popular framework used for developing natively compiled applications for mobile, web, and desktop. When building a mobile application, it’s essential to provide users with an optimal user experience. One aspect of this experience is the keyboard input type. In Flutter, you can change the keyboard type input on a TextField to suit your needs. In this article, we will explore how to achieve this.
Changing Keyboard Type Input

To change the keyboard type input on a TextField in Flutter, you can use the `keyboardType` property. This property allows you to specify the type of keyboard to display when the TextField is focused.
Here is an example of how to change the keyboard type input:
“`dart
TextField(
keyboardType: TextInputType.emailAddress,
decoration: InputDecoration(
labelText: ‘Email’,
