## Dart Firebase Admin
Welcome! This project is a port of [Node's Firebase Admin SDK](https://github.com/firebase/firebase-admin-node) to Dart.
⚠️ This project is still in its early stages, and some features may be missing or bugged.
Currently, only Firestore is available, with more to come (auth next).

## Getting started
### Connecting to the SDK
Before using Firebase, we must first authenticate.
There are currently two options:
- You can connect using environment variables
- Alternatively, you can specify a `service-account.json` file
#### Connecting using the environment
To connect using environment variables, you will need to have
the [Firebase CLI](https://firebaseopensource.com/projects/firebase/firebase-tools/) installed.
Once done, you can run:
```sh
firebase login
```
And log-in to the project of your choice.
From there, you can have your Dart program authenticate
using the environment with:
```dart
import 'package:dart_firebase_admin/dart_firebase_admin.dart';
void main() {
final admin = FirebaseAdminApp.initializeApp(
'',
// This will obtain authentication information from the environment
Credential.fromApplicationDefaultCredentials(),
);
// TODO use the Admin SDK
final firestore = Firestore(admin);
firestore.doc('hello/world').get();
}
```
#### Connecting using a `service-account.json` file
Alternatively, you can choose to use a `service-account.json` file.
This file can be obtained in your firebase console by going to:
```
https://console.firebase.google.com/u/0/project//settings/serviceaccounts/adminsdk
```
Make sure to replace `` with the name of your project.
One there, follow the steps and download the file. Place it anywhere you want in your project.
**⚠️ Note**:
This file should be kept private. Do not commit it on public repositories.
After all of that is done, you can now authenticate in your Dart program using:
```dart
import 'package:dart_firebase_admin/dart_firebase_admin.dart';
Future main() async {
final admin = FirebaseAdminApp.initializeApp(
'',
// Log-in using the newly downloaded file.
Credential.fromServiceAccount(
File(''),
),
);
// TODO use the Admin SDK
final firestore = Firestore(admin);
firestore.doc('hello/world').get();
// Don't forget to close the Admin SDK at the end of your "main"!
await admin.close();
}
```
## Firestore
### Usage
First, make sure to follow the steps on [how to authenticate](#connecting-to-the-sdk).
You should now have an instance of a `FirebaseAdminApp` object.
You can now use this object to create a `Firestore` object as followed:
```dart
// Obtained in the previous steps
FirebaseAdminApp admin;
final firestore = Firestore(admin);
```
From this point onwards, using Firestore with the admin ADK
is roughly equivalent to using [FlutterFire](https://github.com/firebase/flutterfire).
Using this `Firestore` object, you'll find your usual collection/query/document
objects.
For example you can perform a `where` query:
```dart
// The following lists all users above 18 years old
final collection = firestore.collection('users');
final adults = collection.where('age', WhereFilter.greaterThan, 18);
final adultsSnapshot = await adults.get();
for (final adult in adultsSnapshot.docs) {
print(adult.data()['age']);
}
```
Composite queries are also supported:
```dart
// List users with either John or Jack as first name.
firestore
.collection('users')
.whereFilter(
Filter.or([
Filter.where('firstName', WhereFilter.equal, 'John'),
Filter.where('firstName', WhereFilter.equal, 'Jack'),
]),
);
```
Alternatively, you can fetch a specific document too:
```dart
// Print the age of the user with ID "123"
final user = await firestore.doc('users/123').get();
print(user.data()?['age']);
```

## Auth
### Usage
First, make sure to follow the steps on [how to authenticate](#connecting-to-the-sdk).
You should now have an instance of a `FirebaseAdminApp` object.
You can now use this object to create a `Auth` object as followed:
```dart
// Obtained in the previous steps
FirebaseAdminApp admin;
final auth = Auth(admin);
```
You can then use this `Auth` object to perform various
auth operations. For example, you can generate a password reset link:
```dart
final link = await auth.generatePasswordResetLink(
'[email protected]',
);
```

## Messaging
### Usage
First, make sure to follow the steps on [how to authenticate](#connecting-to-the-sdk).
You should now have an instance of a `FirebaseAdminApp` object.
Then, you can create an instance of `Messaging` as followed:
```dart
// Obtained in the previous steps
FirebaseAdminApp admin;
final messaging = Messaging(messaging);
```
You can then use that `Messaging` object to interact with Firebase Messaging.
For example, if you want to send a notification to a specific device, you can do:
```dart
await messaging.send(
TokenMessage(
// The token of the targeted device.
// This token can be obtain by using FlutterFire's firebase_messaging:
// https://pub.dev/documentation/firebase_messaging/latest/firebase_messaging/FirebaseMessaging/getToken.html
token: "",
notification: Notification(
// The content of the notification
title: 'Hello',
body: 'World',
),
),
);
```
