How to read values from firestore array with flutter

I have following array in firestore

enter image description here

I am using following code to read it;

    List companies= [];
       fireData()  async {
  var _dataC =  await 
  FirebaseFirestore.instance.collection('comp').doc(uida).collection('comp').get();
 var comList= await _dataC.docs.map((e) => e.get('skills')).toList();

 setState(() {
   companies=comList;
  });
  }

I am able to fetch records and put them in a listview builder. But these 3 names are not appearing with their index but everything is appearing in one text as [tcs, infy, wipro]

I need to get individual elements on the list. Length of the list is showing as 1 instead of 2.

I am using following code show these in ListView builder;

        ListView.builder  (
        itemCount: companies.length,
        itemBuilder: (BuildContext context, int index){
        return Container(
        width: size.width * 0.1,
        child:  Card(
          child: ListTile(
            leading: Text( companies[index][0], style: 
          TextStyle(color: Colors.black),),
          ),), ); })

With 0, i can manually access first element but i need a list view with all the elements displayed in separate cards. Please

I think by taking the list of skills, and writing it to a list, you created a List<List>. So, either access it by calling skills[0][0], skills[0][1], etc or don't write it toList(), it's already a list, so you don't need to write it as such.
