The streamSnapshot.data!.data() will return a list of image url.

///check the data is null or not
final images = List.from(streamSnapshot.data!.data());

return Column(
  children: images
      .map(
        (e) => Container(
          decoration: BoxDecoration(
            borderRadius: BorderRadius.circular(20),
            image: DecorationImage(
              fit: BoxFit.cover,
              image: NetworkImage(e),
            ),
          ),
        ),
      )
      .toList(),
