Hi everyone I’m little stuck at a place. I’m trying to upload a image(not base64) to a rest api but can’t upload. Can anyone please tell me what wrong am I doing???

import { Component } from '@angular/core';

  templateUrl: 'sec-four.html'
})
export class SecFourPage {

  imageURI:any;
  imageFileName:any;
  constructor(public navCtrl: NavController, private camera: Camera, private transfer: FileTransfer, private file: File, public actionSheetCtrl: ActionSheetController, public toastCtrl: ToastController, public platform: Platform, public loadingCtrl: LoadingController) {

  }

    let actionSheet = this.actionSheetCtrl.create({
      title: 'Select Image Source',
      buttons: [

              this.imageURI =  imageData;
            }, (err) => {
              // Handle error
            });
