zxing scanner module is not working

[sumant52]

error NG8001: 'zxing-scanner' is not a known element:

1. If 'zxing-scanner' is an Angular component, then verify that it is part of this module.
2. If 'zxing-scanner' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.
3. This error is displaying after installing ngx-scanner module using npm.

Make sure you add the appropriate modules to app.module

I'm running into the same problem using these versions of the libraries inside an ionic 6 project:

    "@zxing/browser": "^0.1.1",
    "@zxing/library": "^0.19.1",
    "@zxing/ngx-scanner": "^3.6.2",

Did you manage to fix the problem @sumant52 ?

[alberthoekstra]

I forgot to import the module in the specific module of the page. So for example barcodescanner.module.ts instead of app.module.ts

That fixed it for me
