Cannot get '@ionic-native/file/ngx' to work

Ionic Framework ionic-v3
1

my app always fails with in the console :

Error: Uncaught (in promise): NullInjectorError: StaticInjectorError(AppModule)[CustomersPage -> File]:
StaticInjectorError(Platform: core)[CustomersPage -> File]:
NullInjectorError: No provider for File!

i dont even use the file in any function right now , just importing ‘@ionic-native/file/ngx’

already makes teh app fail … no matter if serve, run browser , cordova run android or capacitor run android …

holy shit its really hard to get into ionic with the fractured knowledgebase … ionic 3 , ioic 4 , cordova , capacitor … every tutorial is different , every example code on github or stack overflow is different , i now tried several methods just to implement a file api at all , not even doing anything with it

ahh man i forgot to put in app.module.ts

do i then need to import again in my page.ts ? or is the provider the same in every page ?

Please see the ionic-native docs for ionic-angular@v3
