WinRTBarcodeScanner undefined - windows 10 app

[numericgraphics]

Hello, I realize an ionic application with the PhoneGap Plugin BarcodeScanner. The application is intended to be used on windows 10. I tested my code on android without any worries. On windows 10 I get an error: WinRTBarcodeScanner is undefined in the developer console. I installed the plugin with CLI cordova. I use for testing DELL VENUE PRO 11 with windows 10. The plugin is installed correctly, the Reader.cs file is present. The error occurs when calling the startBarcodeSearch function. do u have an idea or a solution to this problem, thank you in advance and thank you for your work.
