WKWebview and "file://" - doesn't work even after removing file://

Ionic Framework ionic-v3

Hi, is there anyone displaying local images stored by cordova file whilst using WKWebview ? I read that WKWebView doesn’t support file:// and removing it should work (as per @mhartington’s comment here)

so this is my code:

(Note: I am using the ionic team’s WKWebview fork via ionic cordova plugin add https://github.com/ionic-team/cordova-plugin-wkwebview-engine.git --save

// Always get the accurate path to your apps folder
  public getFullPath(img) {
    let path =  this.file.dataDirectory + img; // same as cordova.file.dataDirectory
    if (this.platform.is('ios'))
    {
      //console.log ("removing path...");
      if (path.startsWith("file://")) {
        path = path.slice(7);
        //console.log ("SLICED");
      }
    // an example of the path returned /var/mobile/Containers/Data/Application/9EFDFC21-754D-46BF-890C-A2CAE8B4361C/Library/NoCloud/1499219374621.jpg
    }
}

And the template does
<img src="{{getFullPath(item.photo)}}" />

Everything works without WKWebView. Thanks
