How to display all data in array?-CodePudding

I'm trying to display data from an array in firestore. I displayed it, but only [0] in the array is showing. I'm trying to get all the data in the array to show.

CodePudding user response：

try this

title: Text(snapshot.data![index]['posts']['postText']),

But you're telling it to display only post [0]!...

If there are more posts in each document, and you want to display all of them, you need to make a for-loop or something. For example:

    itemBuilder: ((_, index) {
      List<Widget> tiles = [];

      for (Map post in snapshot.data![index]['posts']) {
        tiles.add(
            ListTile(
              title: Text(post['postText']),
              subtitle: Text(post['fromUser']),
            ));
      }

      return Expanded(
        child: Column(
          children: tiles,
        ),
      );
    }),

And btw... Next time you ask a qn, plz paste your code as text rather than an image! So that we can copy-paste it into our answer, rather than having to retype it from the image. It's so easy to make a mistake and then you get an error coz we didn't copy it right.
