You can use regex

NOTE: only 10 digit validate. by below method.

String validateMobile(String value) {
  String pattern = r'(^(?:[+0]9)?[0-9]{10,12}$)';
  RegExp regExp = new RegExp(pattern);

  if (value.length == 0) {
      return 'Please enter mobile number';
  } else if (!regExp.hasMatch(value)) {
      return 'Please enter valid mobile number';
  }

  return null;
}
