Remote Config Feature Manager for Flutter

[]

Feature manager allows you to hide some unfinished/secret feature from your users, or experiments, that can be managed
from remote data source or local settings.

If you need only local feature toggles or preferences use Feature Manager

Getting Started

• Installation
• Basic Usage
• If you want to use A/B testing or feature toggling with Firebase Remote Config use Remote Config Feature Manager

Installation

Add

remote_config_feature_manager : ^lastest_version

to your pubspec.yaml, and run

flutter packages get

in your project’s root directory.

Setup Firebase Remote Config in your project.

To get started with Firebase Remote Config for Flutter, please see the documentation available at https://firebase.flutter.dev

Basic Usage

Create feature list

Create file where you will store your feature list and create features inside. Don’t forget to specify remoteSourceKey from Remote Config.

Active feature manager

To create RemoteConfigFeatureManger provide SharedPreferences and FirebaseRemoteConfig instances.

...
final RemoteConfigFeatureManager featureManager = RemoteConfigFeatureManager(
          sharedPreferences: sharedPreferences,
          firebaseRemoteConfig: remoteConfig,
      );
...

To fetch and active feature values use activate function.

...
await featureManager.activate(
            Features.values,
            minimumFetchInterval: const Duration(
                  minutes: 5,
            ),
      );
...

If you want to initialize FirebaseRemoteConfig elsewhere, you can just use refresh function to map remote values to your features.

...
featureManager.refresh(Features.values);
...

Using RemoteConfigFeatureManager check whether feature is enabled.
Preferable way to create RemoteConfigFeatureManager instance is to use DI (Provider, GetIt etc.).

Modify remote feature values in Firebase Console

Modify feature values in DEBUG (develop) mode

To do it, you can simply open DeveloperPreferences screen in any part of your app.
You should pass list of your features as parameter for this screen.

P.S. You should hide this button for production builds.

Feature parameters

enum FeatureType { feature, experiment }

enum FeatureValueType { text, toggle, doubleNumber, integerNumber, json }
