Supabase query return string instead of list

I want to get the parameters interest.name, interest.description, interest.category.name as String with the value that is currently returning a list. They are translations and I select the value depending the code with the code .eq('...',languageCode) that I show below

Is there a way to do this in supabase?

this is my json at the moment:

{
   "id":"f36686d7-f815-4372-aba8-4d3f7fe1a4a5",
   "member_id":"c2579821-54e4-42c8-8b35-b522a34712a2",
   "interest_id":"yoga",
   "interest":{
      "id":"yoga",
      "name":[
         {
            "name":"Yoga",
         }
      ],
      "active":true,
      "category":{
         "id":"fitness",
         "icon":"meditation",
         "name":[
            {
               "name":"Fitness"
            }
         ],
         "color":"primary200",
         "active":true,
      },
      "category_id":"fitness",
      "description":[
         {
            "description":"Physical activity focused on poses and meditation."
         },
         {
            "description":"Actividad física basada en posturas y meditación."
         }
      ],
      "interest_type_id":"fitness"
   }
}

This is the code of the query:

    var query = _supabaseClient.from('member_interests').select('''
          *,
          interest:interest_id(
            *,
            category:category_id(
              *,
              name: category_translations(name)
            ),
            name: interest_translations(name),
            description: interest_translations(description)
          )
        ''').eq('member_id', memberId);

    if (languageCode != null) {
      query = query.eq(
        'interest.interest_translations.language_code',
        languageCode,
      );

      query = query.eq(
        'interest.category.category_translations.language_code',
        languageCode,
      );
      
    }

    final data = await query;

    return data.map(MemberInterest.fromJson).toList();
  }
