System.err: TypeError: Cannot read property 'getInstance' of undefined

[ngoahamos]

Hello Guys,
i'm getting the following error in Android. I don't know what am doing wrong. Any help will be much appreciated.
Thanks.

main.ts | i also moved it to app.component.ts still had the same error.
`import { platformNativeScriptDynamic } from "nativescript-angular/platform";

import { AppModule } from "./app.module";
import * as Firebase from 'nativescript-plugin-firebase';

Firebase.init({})
.then((instance) => {
console.log('firebase.init done');
}, (error) => {
console.log(firebase.init error: ${error});

});
platformNativeScriptDynamic().bootstrapModule(AppModule);`

Can you try removing the platforms/android folder and run again?

Hello @EddyVerbruggen thanks for your prompt response. Still getting the same error after doing the above.

[ngoahamos]

created firebase.nativescript.json file first before installing the plugin and now it's working.

Hey @ngoahamos, I'm facing the same issue. Can you tell me where did you put this file and what did you put in it?

[EddyVerbruggen]

You should not have to create that file manually.. when installing the plugin you should be prompted with a few questions which should create that file for you (so next ‘npm i’ you won’t be prompted again).

Hi Eddy, I used the Sidekick to install the plugin and it didn't prompt me for anything and the file was not created.

[ngoahamos]

@EddyVerbruggen didn't get the prompt, so i thought everything was taken care of, then i started getting errors.
@VeeK727 in the root folder. in the same folder your package.json is.
Modify it to suit your need.

Ah, sidekick, makes sense. Would it help if I add a note about this in the readme, or would nobody read that anyway? 🤭

[ngoahamos]

It will be very helpful if you add a note about it in the readme.
