title: Listview.builder Positioning a widget on another widget
body: <p>I'm trying to make an application like Instagram. But I can't fully view the zoomed picture because of other pictures.</p>
  <p><strong>Codes:</strong></p>
  <pre><code>List colors = [
      Colors.green,
      Colors.blue,
      Colors.red,
    ];
  
    @override
    Widget build(BuildContext context) {
      return Scaffold(
        appBar: AppBar(
          title: Text(&quot;Demo&quot;),
        ),
        body: ListView.builder(
          itemCount: 3,
          itemBuilder: (_, int index) {
            TransformationController controller = TransformationController();
            return Container(
              child: InteractiveViewer(
                transformationController: controller,
                onInteractionEnd: (_) {
                  setState(() {
                    controller.toScene(Offset.zero);
                  });
                },

                  colorFilter: ColorFilter.mode(colors[index], BlendMode.color),
                  child: FlutterLogo(),
                ),
              ),
