A month of Flutter: setting up Firebase Firestore

After a user signs in with Google and registers, their info needs to be saved to a databasee. I'm going to use Firebase Firestore as my backend. Within the birb codebase I'm going to create a server directory and initialize a Firestore project inside it using firebase-tools.

$ firebase init ######## #### ######## ######## ######## ### ###### ######## ## ## ## ## ## ## ## ## ## ## ## ###### ## ######## ###### ######## ######### ###### ###### ## ## ## ## ## ## ## ## ## ## ## ## #### ## ## ######## ######## ## ## ###### ######## You 're about to initialize a Firebase project in this directory: /home/abraham/Development/birb ? Which Firebase CLI features do you want to setup for this folder? Press Space to select features, then Enter to confirm your choices. ◯ Database: Deploy Firebase Realtime Database Rules ❯◉ Firestore: Deploy rules and create indexes for Firestore ◯ Functions: Configure and deploy Cloud Functions ◯ Hosting: Configure and deploy Firebase Hosting sites ◯ Storage: Deploy Cloud Storage security rules

I choose the same Firebase project being used for authentication, the default Firestore Rules file, and the default Firestore indexes file. By default .firebaserc is not .gitignored . I have added my .firebasrc to .gitignore because this is an open source project. Anyone who forks Birb will need to set up their own Firebase project.

In the Firebase console I will now enable Firestore for the project.

Here are the default firestore.rules that just say don't allow reads or writes.

service cloud . firestore { match / databases / { database } /documents { match / { document =** } { allow read , write : if false ; } } }

Deploying the rules is handled with the firebase-tools Node package.

$ npx firebase deploy === Deploying to 'birb-app-dev' ... i deploying firestore i firestore: checking firestore.rules for compilation errors... i firestore: reading indexes from firestore.indexes.json... ✔ firestore: rules file firestore.rules compiled successfully i firestore: uploading rules firestore.rules... ✔ firestore: deployed indexes in firestore.indexes.json successfully ✔ firestore: released rules firestore.rules to cloud.firestore ✔ Deploy complete ! Project Console: https://console.firebase.google.com/project/birb-app-dev/overview

Installing the cloud_firestore package in pubspec.yaml happens last.

Before integrating with the Flutter code, I'm going to write some rules with so come back soon for that article.
