                      ),

There is no option to change TextStyle. Only I found a variant add cast text on the bottom of the otp widget. The errorPinTheme make invisible and almost no size:

      final errorPinTheme = PinTheme(
          width: 0,
          height: 0,
          textStyle: const TextStyle(
            fontSize: 0,
            color: Colors.transparent,
          ),
          decoration: BoxDecoration(
            color: fillColor,
            borderRadius: BorderRadius.circular(5),
            border: Border.all(color: borderColor),
          ),
        );

and in the Column(
        children: [ ... //


 errorPinTheme: errorPinTheme,
                        submittedPinTheme: defaultPinTheme.copyWith(
                          decoration: defaultPinTheme.decoration!.copyWith(
                            color: fillColor,
                            borderRadius: BorderRadius.circular(5),
                            border: Border.all(color: focusedBorderColor),
                          ),
                        ),
                      ),
                    ),
                  ),
                  if (currentErrorMessage != null)
                    Padding(
                      padding: const EdgeInsets.only(top: 8.0),
                      child: Text(
                        currentErrorMessage!,
                        style: const TextStyle(
                          fontSize: 14,
                          fontWeight: FontWeight.w400,
                          color: Color(0xFFE0193D),
                        ),
                        textAlign: TextAlign.left,
                      ),
                    ),
