How to create number input field in Flutter

0 votes

I can't seem to figure out how to make a Flutter input field that only accepts numeric input and opens a numeric keyboard. Are Flutter material widgets able to accomplish this? Although some GitHub discussions seem to suggest that this is a supported function, I haven't been able to locate any related documentation.

Yes, Flutter has a built-in widget called TextField that can be used to create input fields for various types of input, including numeric input. To restrict the input to only numbers and show a numeric keyboard, you can use the keyboardType parameter of the TextField widget.

Here's an example of how to create a numeric input field using TextField:

TextField(
  keyboardType: TextInputType.number,
  decoration: InputDecoration(
    hintText: 'Enter a number',
  ),
);

In this example, the keyboardType parameter is set to TextInputType.number, which tells Flutter to show a numeric keyboard when the input field is selected. The decoration parameter is used to add a hint text to the input field.

You can also use other TextInputType values to customize the keyboard for different types of input, such as TextInputType.phone for phone numbers or TextInputType.emailAddress for email addresses.

I hope this helps!
