[nativescript-barcodescanner] [Android] blank page in release mode

[ptomasini]

I've a very strange problem:

1- created new test application with:

ns create --template @nativescript/template-drawer-navigation-ng

2- installed plugin:

npm install @nstudio/nativescript-barcodescanner

3 - modified home.component.ts

import { BarcodeScanner} from "@nstudio/nativescript-barcodescanner";

  CameraScan(): void {
    var barcodescanner = new BarcodeScanner;
  }

Compiling and installing in debug mode (tns run android --device XYZ) the home page is displayed. Compiling and installing in release mode (tns run android --device XYZ --release --key-store....) the home page is displayed blank.

No error, no crash, no log error. The page is simply blank.

Commenting out the line with BarcodeScanner reference

  CameraScan(): void {
    // var barcodescanner = new BarcodeScanner;
  }

the home page is display as expected.

package.js

{
  "name": "TestScannerApp",
  "main": "src/main.ts",
  "version": "1.0.0",
  "private": true,
  "dependencies": {
    "@angular/animations": "~13.2.0",

    "@nativescript/webpack": "~5.0.6",
    "@ngtools/webpack": "~13.2.0",
    "typescript": "~4.5.5"
  }
}

Physical device is Android 8.0.0.

Any Idea how to solve?

I'm also seeing this issue in production release. Works fine while in dev/debuggon mode. Below is an error from release build:
