Streambuilder not iterating over the if statement

I have built a streambuilder that has two-page builders. I realized it is not iterating over the last if statement, does anyone knows a function so that I can get it to iterate over the last if statement too?

The condition of all if statements are being met

My widget:

StreamBuilder2<QuerySnapshot<Map<String, dynamic>>,
              QuerySnapshot<Map<String, dynamic>>>(
          streams: Tuple2(stream1, stream2),
          builder: (ctx, snapshots) {
            if (!snapshots.item1.hasData && !snapshots.item2.hasData) {
              return const Center(
                child: CircularProgressIndicator(),
              );
            }
            if (snapshots.item1.hasData) {
              return PageView.builder(
                  itemCount: snapshots.item1.data!.docs.length,
                  itemBuilder: ((context, index) {
                    INvideoPlayerController = VideoPlayerController.network(
                      snapshots.item1.data!.docs[index].get('url'),
                    )
                      ..setLooping(true)
                      ..initialize()
                          .then((value) => INvideoPlayerController!.play());
                    return AspectRatio(
                      aspectRatio: INvideoPlayerController!.value.aspectRatio,
                      child: VideoPlayer(INvideoPlayerController!),
                    );
                  }));
            }

            if (snapshots.item2.hasData ) {
              return PageView.builder(
                  itemCount: snapshots.item2.data!.docs.length,
                  itemBuilder: ((context, index) {
                    return FittedBox(
                      child: Container(
                        margin: const EdgeInsets.all(7),
                        child: FadeInImage.memoryNetwork(
                            fit: BoxFit.cover,
                            placeholder: kTransparentImage,
                            image:
                                snapshots.item2.data!.docs[index].get('url')),
                      ),
                    );
                  }));
            }
            return Text('done');
          }),

What I have tried:

I tried using one-page builder but I was getting the same problem that I was not able to exit the 2nd if loop even after the data was not present in it which gave range errors.

I cannot find a solution on the net on how to make it iterate over another loop.
