How to create number input field in Flutter?

Question

I\'m unable to find a way to create an input field in Flutter that would open up a numeric keyboard. Is this possible with Flutter material widgets? Some github discussions

Here is code for actual Phone keyboard on Android:

Key part: keyboardType: TextInputType.phone,

  TextFormField(
    style: TextStyle(
      fontSize: 24
    ),
    controller: _phoneNumberController,
    keyboardType: TextInputType.phone,
    decoration: InputDecoration(
      prefixText: "+1 ",
      labelText: 'Phone number'),
    validator: (String value) {
      if (value.isEmpty) {
        return 'Phone number (+x xxx-xxx-xxxx)';
      }
      return null;
    },
  ),
