Pageview in flutter/dart is not getting scrollable

Question

I want to make horizontal scrollable images widget. I placed pageview for that but it is neither working nor I got any error. Don't know what to do.

Map<String, dynamic> documentData = snapshot.data.data();

                //List of images
                List imageList = documentData["images"];

                return ListView(
                  padding: EdgeInsets.all(0),
                  children: [
                    Container(
                        height: 400,
                        child: PageView(
                          children: [
                            for (var i = 0; i < imageList.length; i++)
                                Container(
                                    child: Image.network(
                                  "${imageList[i]}",
                                  fit: BoxFit.cover,
                                ))
                          ],
                        )),

These new containers created in the for loop wasn't added to the list of children. Use spread operator or PageView.builder instead. Example:

    PageView.builder(
              itemcount: imageList.length,
              itemBuilder:(BuildContext context, int index ){
              return Container(
                                 child: Image.network(
                                      "${imageList[index]}",
                                      fit: BoxFit.cover,
                                    ));
    
    },
),
              

                            

OR

PageView(
                          children: [
                            for (var i = 0; i < imageList.length; i++)
                                ...[Container(
                                    child: Image.network(
                                  "${imageList[i]}",
                                  fit: BoxFit.cover,
                                )),]
                          ],
                        )
