How to make list view to listview.builder in flutter?

Question

buildComments() {

return StreamBuilder(

    stream: commentRef
        .document(postId)
        .collection('comments')
        .orderBy('timestamp', descending: false)
        .snapshots(),

    builder: (context, snapshot) {
      if (!snapshot.hasData) {
        return circularProgress();
      }

      List<Comment> comments = [];
      snapshot.data.documents.forEach((doc) {
        print(comments);
        comments.add(Comment.fromDocument(doc));
      });

      return ListView(
        children: comments,
      );
    });
}

I was trying to convert it in list view.builder but it gives me error you can can't use list instead of Widget, Can anyone solve this problem.

Solution

You should do the following:

      if (snapshot.connectionState == ConnectionState.done) {
        return ListView.builder(
            shrinkWrap: true,
            itemCount: snapshot.data.documents.length,
            itemBuilder: (BuildContext context, int index) {
              return ListTile(
                contentPadding: EdgeInsets.all(8.0),
                title: Text(snapshot.data.documents[index].data["name"]),
              );
            });

Assuming you have name in the document.
