Remote Config

caution

This is a beta FlutterFire plugin and therefore is not yet production quality.

What does it do?#

Firebase Remote Config is a cloud service that lets you change the behavior and appearance of your app without requiring users to download an app update. When using Remote Config, you create in-app default values that control the behavior and appearance of your app. Then, you can later use the Firebase console or the Remote Config backend APIs to override in-app default values for all app users or for segments of your user base. Your app controls when updates are applied, and it can frequently check for updates and apply them with a negligible impact on performance.

Installation#

Legacy
Null safety

Ensure you're using the Flutter stable channel:

$ flutter channel stable

If your app is mixing legacy and null-safe packages, use the --no-sound-null-safety flag:

$ flutter run --no-sound-null-safety

For legacy package imports, place the following ignore comment to hide Dart analyzer warnings:

// ignore: import_of_legacy_library_into_null_safe
import 'package:firebase_remote_config/firebase_remote_config.dart';

1. Add dependency#

Legacy

pubspec.yaml
