shouldIconPulse should be false by default.

Should icon pulse is a very specific behaviour. That is something that should be set to false by default. And only when needed it should be set to true by the developer.

    final flushBar = Flushbar(
      flushbarPosition: FlushbarPosition.TOP,
      flushbarStyle: FlushbarStyle.GROUNDED,
      duration: Duration(seconds:1),
      animationDuration: Duration(seconds:1),
      backgroundColor: ThemeColors.black,
      icon: Icon(
        Icons.check,
        color: Colors.white,
      ),
      shouldIconPulse: false,
      messageText: Text(
        message,
        style: ThemeTextStyles.flushBarStyle,
      ),
    );

It seems that shouldIconPulse: false doesn't work in FlushbarHelper.
