Flutter How to send and show captured image/ video to next page? - flutter

Question

I've created a screen where I can use a button to open the camera and take video. And above that button, I made a container to display the video. But I want to show this container containing video to display on the next page. As I am new to flutter, I believe my code is messy. Can you help me with how to do this?
And how to show multiple videos on a screen after taking them through this camera in a loop like this image here?
Here is my code -
class video_record02 extends StatefulWidget {
final Function? onSelectVideo;
const video_record02({Key? key, this.onSelectVideo});
#override
_video_record02State createState() => _video_record02State();
}
class _video_record02State extends State<video_record02> {
String dropdownValue = 'Bedroom';
File? storedVideo;
Future<void> _takeVideo() async {
final picker = ImagePicker();
final videoFile = await picker.pickVideo(
source: ImageSource.camera,
preferredCameraDevice: CameraDevice.rear,
maxDuration: Duration(
seconds: 25,
),
);
if (videoFile == null) {
return;
}
final rlyvideoFile = File(videoFile.path);
setState(() {
storedVideo = rlyvideoFile;
});
final appDir = await syspaths.getApplicationDocumentsDirectory();
final fileName = path.basename(rlyvideoFile.path);
final savedVideo = await rlyvideoFile.copy('${appDir.path}/$fileName');
widget.onSelectVideo?.call(savedVideo);
}
