Start Camera Preview hidden?

Ionic Framework ionic-v3
1

Hi, i want to start the camera preview which is delivered throught the camera-preview plugin. This my code for the camera activation:

  initCamera() {
  	this.FLASH_LIGHT_STATUS = false;
  	this.CAMERA_STATUS = false;
  	this.cameraPreview.startCamera(this.cameraOptions).then(() => {
  		console.info("Camera started.");
  		this.cameraPreview.hide().then(() => console.info("Inital hide of preview.")).catch(e => console.error(e));
	  }).catch(e => console.error(e));
  	//this.cameraPreview.hide().then(() => console.info("Inital Cam hide.")).catch(e => console.error(e));
  }

My problem is that if i remove the initial hide command the camera-preview works fine and i can hide/show it like i want. But after i activate the cameraPreview.hide() in the then() block of startCamera() the flashlight works, but i can’t activate/show the camera preview. This is my toggle function:

  toogleCamera() {
  	console.info("Toggle camera. CAM_STATUS: " + this.CAMERA_STATUS);
  	if(this.CAMERA_STATUS){
  		this.cameraPreview.hide().then(() => console.info("Camera hidden.")).catch(e => console.error(e));
  		this.CAMERA_STATUS = false;
  	}else{
  		this.cameraPreview.show().then(() => console.info("Show Camera Preview")).catch(e => console.error(e));
  		this.CAMERA_STATUS = true;
  	}
  }

This is what “ionic info” shows me:

cli packages: (C:\Users\Andreas\AppData\Roaming\nvm\v7.9.0\node_modules)

    @ionic/cli-utils  : 1.9.2
    ionic (Ionic CLI) : 3.9.2

global packages:

    Cordova CLI : 6.5.0

local packages:

    @ionic/app-scripts : 2.1.4
    Cordova Platforms  : android 6.1.2
    Ionic Framework    : ionic-angular 3.6.0

System:

    Android SDK Tools : 26.0.2
    Node              : v7.9.0
    npm               : 4.2.0
    OS                : Windows 10

I’m using this version of camera preview:
<plugin name="cordova-plugin-camera-preview" spec="~0.9.0" />
I cant figure out why it behaves that way.

Update: Problem solved

I solved my problem by removing the installed version of the plugin and replacing it with the most recent version from github.
