FileDialog filemode not working

[Vijaykarthikeyan]

I'm trying to save the video file using FileDialog component in QML.For that,I have been using
this statement.
import Qt.labs.platform 1.1

FileDialog {
       id: save_vid_Dialog
       title: "Please choose a file"
       folder: StandardPaths.writableLocation(StandardPaths.MoviesLocation)
       fileMode:FileDialog.SaveFile
       nameFilters: ["AVI files (*.avi)", "Mp4 files (*.mp4)", "MKV files (*.mkv)"]
       onAccepted: {
           console.log(FileDialog.SaveFile)
           save_vid_Dialog.close()
       }
       onRejected: {
           save_vid_Dialog.close()
       }
   }

But,I'm receving this error qrc:/LiveStream.qml:501:8: Unable to assign [undefined] to int
for the line : fileMode:FileDialog.SaveFile
why the filemode is not accepting the value

we have to define only one import statement for dialog component at a time. For my work, Qt.labs.platform 1.1 works fine so I discarded the other one. Like this,I have commented out the Dialogs component

import QtQuick 2.15
import Qt.labs.platform 1.1
import QtQuick.Controls 2.15
import QtGraphicalEffects 1.15
import QtQuick.Layouts 1.15
//import QtQuick.Dialogs 1.3
