iOS Installation

Before using FlutterFire on iOS, you must first connect to your Firebase project with your iOS application.

Generating a Firebase project configuration file

On the Firebase Console, add a new iOS app or select an existing iOS app for your Firebase project. The "iOS bundle ID" must match your local project bundle ID. The bundle ID can be found within the "General" tab when opening ios/Runner.xcworkspace with Xcode.

Download the GoogleService-Info.plist file for the Firebase app.

Installing your Firebase configuration file

Next you must add the file to the project using Xcode (adding manually via the filesystem won't link the file to the project). Using Xcode, open the project's ios/{projectName}.xcworkspace file. Right click Runner from the left-hand side project navigation within Xcode and select "Add files", as seen below:

Select the GoogleService-Info.plist file you downloaded, and ensure the "Copy items if needed" checkbox is enabled:

Enabling use of Firebase Emulator Suite

The Firebase Emulator Suite uses un-encrypted networking connections in order to enable fast, uncomplicated setup. However iOS by default requires encrypted networking connections. If you would like to use any part of the Firebase Emulator Suite to emulate firebase services on your local machine during development, you must allow your iOS app to connect to local network services over insecure connections.

To allow insecure connections, we recommend adding the NSAllowsLocalNetworking key to the NSAppTransportSecurity dictionary in your application's plist file.

Specifically if your app is named 'MyApp', you might add these keys in ios/MyApp/Info.plist:

<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsLocalNetworking</key>
<true/>
</dict>

Initializing FlutterFire

Once complete follow the instructions on Initializing FlutterFire.

iOS Supported Versions

FlutterFire supports an iOS deployment target of 10 or higher, in line with the requirements of the underlying firebase-ios-sdk.
