hello I just get started to use package I first add that to my project , then I apply tag on translation text which I take help from getx like this

class LanguageConstant {
  LanguageConstant._();
  static const String shareYourFelling = 'share_your_felling';
}

class LanguageController extends Translations {
  @override
  Map<String, Map<String, String>> get keys => {
        "fa-IR": {
          LanguageConstant.shareYourFelling:
              "احساسات خودت با <color>پارتنرت<color>به اشتراک بزار"
        },
        "en-US": {
          LanguageConstant.shareYourFelling:
              "Share your feeling with your <color>partner<color>"
        },
      };
}

then i come over to my ui and start using the widget as document say

StyledText(
              text: LanguageConstant.shareYourFelling.tr,
              tags: {
                'color': StyledTextTag(
                  style: AppTextStyle.kHeadlineLarge.copyWith(
                    fontSize: 21,
                    color: themeData.primaryColor,
                  ),
                )
              },
            )

when im running the app i got that error

What version of Flutter are you using? Can you provide the output of the "flutter doctor -v" command?

You need to upgrade to Flutter version 3.10.

is there other way ? I had developed my project with this version

Downgrade StyledText in pubspec.yaml to 7.0.0.
