Unwanted spaces around the zoom widget while using column widget

[GowthamanRavichandran]

I have a requirement where I need to include some widgets above and below the zoom widget. I attempted to add these widgets using the Column widget, but when I placed them above and below the zoom widget, I noticed that there is some gray-colored space added on the left and right sides, as shown in the screenshot below. I have provided an example of my code for your reference. I also tried using the bottomNavigationBar, but encountered the same issue.

Example Code

class MyApp extends StatefulWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  @override
  Widget build(BuildContext context) {
    return SafeArea(
      child: Scaffold(
        body: SizedBox(
          width: MediaQuery.of(context).size.width,
          height: MediaQuery.of(context).size.height,
          child: LayoutBuilder(
            builder: (p0, p1) => Column(
              children: [
                Expanded(
                  child: SizedBox(
                    height: MediaQuery.of(context).size.height,
                    width: MediaQuery.of(context).size.width,
                    child: Zoom(
                      initTotalZoomOut: true,
                      maxZoomHeight: MediaQuery.of(context).size.height,
