Firebase Setup

All the data is stored in Firebase Realtime Database and Firestore database.

In Firebase we store the information about the app, like colors, navigation etc..
And in Firestore is where our actual data is. Like menu content, categories, orders etc..
Let's get started. Create an account in Firebase with your google account.

Follow all the guides in the tabs.

Create Project
Create Realtime DB
Insert Data
Create Firestore DB
Create Firestorage
Authentication
Google Login
Open Firebase and Click on "Add Project".
Accept terms, and create the project.
Go to Database and then click on the button called "Create database".
After clicking on the button it should appear a window that will ask you about security rules. Click on the Start in test mode and after that click Enable.
But for production, this is a good starting point. This will allow edit and write to all registered users.
{
"rules": {
".read": true,
".write": "auth !== null"
}
}
In your realtime database, click on the three dots on right, and select Import JSON. In the project you downloaded from CodeCanyon there is a folder SetupData there is one .json file. Select that file and import it to your database.
Go in Databases ->Cloud Firestore
or
Then, a pop up will appear.
For now, use Start in test mode.
Firebase Storage by default is not initialized. You will need to click on "Storage" and active the Firestorage Bucket.
Go into Firebase console and click on Authentication and after that click on Set up sign-in method.
Click on Email/Password and enable them and click Save.
Now click on Users and now you should be able to click on Add user.
Enter your email and password click Add user.
If you want to allow Google authentication, you have to do is to enable the Google Auth Provider as on the image below.
Next, scroll below and there you should add your authorized domain. Place where the Google Login will be performed.
