The function was anticipating 2 arguments, however, only 1 was provided, resulting in error code TS

After upgrading my Ionic app from version 3 to version 4, I encountered some camera issues. The following error appeared in the console when running ionic serve:

ERROR in src/app/register/register.page.ts(50,4): error TS2554: Expected 2 arguments, but got 1. [ng] src/app/register/register.page.ts(53,63): error TS2749: 'Camera' refers to a value, but is being used as a type here.

See the code snippet from register.ts:

import { Component, ViewChild, OnInit } from '@angular/core';
import { ScrollDetail } from '@ionic/core';
import { NavController, LoadingController, ToastController } from '@ionic/angular';
import { Http, Response, Headers, RequestOptions }  from "@angular/http";
import { map } from 'rxjs/operators';
import { Observable } from 'rxjs/Observable';
import { SignaturePad } from 'angular2-signaturepad/signature-pad';
import { Storage } from '@ionic/storage';
import { Camera, CameraOptions } from '@ionic-native/camera';

@Component({
  selector: 'app-register',
  templateUrl: './register.page.html',
  styleUrls: ['./register.page.scss'],
})
export class RegisterPage implements OnInit {

showToolbar = false;
capturedSnapURL:string;

// Rest of the code...

Can anyone assist me in identifying the issue in my code?

Answer №1

To add the Camera functionality in your Ionic app, simply include Camera in the providers array within the app.module.ts file.

import { Camera } from '@ionic-native/camera';

providers: [
   Camera 
]

Answer №2

Here is how you can import the camera plugin:

import { Camera, CameraOptions } from '@ionic-native/camera/ngx';

To use the SignaturePad component in your HTML, make sure to give it an Id (such as 'componentId') and update your view component code as shown below:

@ViewChild('componentId', { static: true } ) signaturePad: SignaturePad;
