Using Linkify in custom action?

I am new to FF. I have a chatbot widget that integrates via voiceflow API ( returns JSON). Is there a way to use Linkify to render the URL in my custom action?

if (jsonObject['type'] == 'text' && jsonObject.containsKey('payload')) {
          if (jsonObject['payload'] is Map<String, dynamic> &&
              jsonObject['payload'].containsKey('message')) {
            ChatAIStruct chatAI = ChatAIStruct(
              type: 'text',
              fromAI: true,
              message: jsonObject['payload']['message'].toString(),
            );
            await updateGlobalChat(chatAI);
          }
        }

The updateGlobalChat updates an app state variable and I show it in my widget as text.
