Google Firebase is using as admin panel and can be used to control users, database, sending push notification and analytics. To find out more about it, please follow this link: http://firebase.google.com

You need to add the SHA-1 key for the project in FirebaseConsole For more details, please check https://developers.google.com/android/guides/client-auth

An app template is a pre-built application with a lot of the core functionality already implemented for you. It allows you to easily customize and add to the template’s code to create the kind of app you want.

To avoid this, you need to turn on “execute” permissions for users (Xcode in this case) of the file.

Steps

1. Go into terminal
2. Navigate to where your script is
3. run chmod 755 export.sh

To filter content that potentially can contain nudity, pornography, or any other abusive content you can add these lines of code to your Could/functions/index.js file

This functionality not included as part of the project and need to be added manually to your cloud functions.

This solution will work for all your platforms: ios/android/web. Also, keep in mind Firebase takes extra for using Cloud Vision API

Before start:

• Be sure you have Cloud Vision API Enabled
• Be sure you have it enabled and your account <project-name>@appspot.gserviceaccount.com has this permission [Storage Object Admin and Storage Object Creator] in Google Console).
• After adding lines below to Could/functions/index.js file be sure to re-deploy cloud functions again.
• After deploying you should see blurOffensiveImages in you Cloud functions list

// file: Could/functions/index.js line 9:
admin.initializeApp();

// add code here

// Node.js core modules
const fs = require('fs');
const mkdirp = fs.promises.mkdir;
const { promisify } = require('util');
const exec = promisify(require('child_process').exec);
const path = require('path');
const os = require('os');

// Vision API
const vision = require('@google-cloud/vision');

        return null;

    const [data] = await visionClient.safeSearchDetection(
