Importing Ionic-Native File plugin in Ionic 4

Question

I am attempting to use the ionic native file plugin, but am receiving an error when attempting to run the app after installation

Partial app.module.ts file:

    ...
    import { File } from '@ionic-native/file';
    ...
    
    @NgModule({
      declarations: [AppComponent],
      entryComponents: [],
      imports: [
        ...
      ],
      providers: [
        ...
        File
      ],
      bootstrap: [AppComponent]
    })
    export class AppModule {}

Error in console is

Uncaught TypeError: Object(...) is not a function
