I will discussing everything about Flutter textformfield keyboardtype in Flutter textformfield like it’s role, it’s usage and how to change Flutter textformfield keyboardtype depending on our app requirements.

What is Flutter Textformfield Keyboardtype?

Flutter textformfield keyboardtype, as the name suggests, it is the keyboard type that popup whenever a Flutter textfield or Flutter textformfield is tapped or focused. Customizing Flutter textformfield keyboardtype means that we can set whether we want to see only numbers or other type of keyboard etc. Let’s start understanding it using a proper example code.

Let’s specify Flutter textformfield keyboardtype to only take numbers. For that you have to use the number property of the text input type class which is implemented in the below code:

 keyboardType: TextInputType.number,

In the above image, you can see that the Flutter textformfield keyboardtype is now set to show only numbers, it can be used to take input like for pin code etc. If the keyboard change is not showing then just hot restart the app and it will word just fine.

We have other options as well like email address, phone numbers which you can test and use depending on your set of requirements. See the below code for both phone and email address.

For phone

keyboardType: TextInputType.phone
