How to resize UnderlineDecoration?

[rrifafauzikomara]

My code like this:

PinFieldAutoFill(
            keyboardType: TextInputType.phone,
            autofocus: true,
            codeLength: 4,
//            currentCode: _code,
            decoration: UnderlineDecoration(
              color: color_text_grey,
              textStyle: TextStyle(
                fontSize: MediaQuery.of(context).size.width / 10,
                color: color_text_black,
                fontWeight: FontWeight.bold,
              ),
            ),
          ),

And the result like this:

Look like it's an issue you should ask here https://github.com/TinoGuo/pin_input_text_field as it's the package providing this decoration, I personally have no idea sorry
