support rtl languages

[yazdanMhmmdi]

Hi
Would it be possible to support rtl languages? i tried to fix it with Directionality widget but seems it's not working.
this is my code:

  Directionality(
                  textDirection: TextDirection.rtl,
                  child: Showcase(
                    key: _two,
                    description: Strings.showcaseFontSizeGuide,
                    animationDuration: Duration(
                        milliseconds:
                            Values.showcaseAnimationTransitionSpeed),
                    showcaseBackgroundColor: IColors.white85,
                    descTextStyle: TextStyle(
                        fontSize: 16 + fontSize, color: IColors.black70),
                    child: Row(
                      children: [
                        FontSizeButtonWidget(
                          isDarkMode: isDark,
                          onTap: () => bolderFontSize(),
                          icon: Icon(
                            Icons.add,
                            size: 16,
                            color: IColors.white85,
                          ),
                        ),
                        FontSizeIndicatorWidget(
                            isDarkMode: isDark,
                            text: fontSize == 2
                                ? Strings.settingsFontSizelarge
                                : fontSize == 0
                                    ? Strings.settingsFontSizeMedium
                                    : Strings.settingsFontSizeSmall),
                        FontSizeButtonWidget(
                          isDarkMode: isDark,
                          onTap: () => thinnerFontSize(),
                          icon: Icon(
                            Icons.remove,
                            size: 16,
                            color: IColors.white85,
                          ),
                        ),
                      ],
                    ),
                  ),
                )

i also attached and marked my output:
