NativeScript plugins are npm packages with some added Native functionality. Therefore, finding, installing, and removing NativeScript plugins works a lot like working with the npm packages you might use in your Node.js or frontend web development. You can find all the available NativeScript plugins at the NativeScript Marketplace: https://market.nativescript.org/.

Let's go ahead and add a NativeScript plugin to our application. The plugin we will be adding is called snackbar. We can add the plugin to our application by using the following code:

> npm i nativescript-snackbar

To use our snackbar plugin, we will initialize the Snackbar in our HomeComponent and call it on the setLanguage method:

import { SnackBar } from 'nativescript-snackbar';

export class HomeComponent {
    ...
    setLanguage() {
        const selectedIndex = e.object.selectedIndex;
        const snackbar = new SnackBar();

        this.appService.language = this.languages[selectedIndex];
        this.translate.setDefaultLang(
            LANGUAGE_MAPPER[this.languages[selectedIndex]]
        );
    
        this.translate.get('LANG_UPDATED').subscribe(val => {
            snackbar.simple(val, 'red', '#067ab4', 3, false);
        });
    }
}

Now, we should be able to see a Snackbar every time we set a language. 

This completes our NativeScript application's implementation. In the next chapter, we will be creating a Reusable Component library and publish it to npm and wrap a Angular Component as a Web Component using Angular Element.
