Answer 1

There is no done button in iOS but we can check the length of the input and clear focus to hide the numberpad keyboard. Implement like below,(it'll work with fix length of number value)

onChanged: (val) {
        if (val.length == 10) { //10 is the length of the phone number you're allowing
          FocusScope.of(context).requestFocus(FocusNode());
        }
      }
