Bullet Train SDK for Flutter #

Bullet Train allows you to manage feature flags and remote config across multiple projects, environments and organisations.

The SDK for Flutter applications for https://bullet-train.io/.

Getting Started #

The client library is available from the https://pub.dev:

dependencies:
  bullet_train:

Usage #

Retrieving feature flags for your project #

For full documentation visit https://docs.bullet-train.io

Sign Up and create an account at https://bullet-train.io/

In your application, initialise the BulletTrain client with your API key:

var bulletClient = BulletTrainClient(apiKey: 'YOUR_ENV_API_KEY')

To check if a feature flag exists and is enabled:

bool featureEnabled = await bulletClient.hasFeatureFlag("my_test_feature");
if (featureEnabled) {
    // run the code to execute enabled feature
} else {
    // run the code if feature switched off
}

To get the configuration value for a feature flag:

var myRemoteConfig = await bulletClient.getFeatureFlagValue("my_test_feature");
if (myRemoteConfig != null) {
    // run the code to use remote config value
} else {
    // run the code without remote config
}

Identifying users #

Identifying users allows you to target specific users from the Bullet Train dashboard.

To check if a feature exists for a given user Identity:

var user = FeatureUser(identifier: 'bullet_train_sample_user');
bool featureEnabled = await bulletClient.hasFeatureFlag('my_test_feature', user: user);
if (featureEnabled) {
    // run the code to execute enabled feature for given user
} else {
    // run the code when feature switched off
}

To get the configuration value for a feature flag for given a user Identity:

var myRemoteConfig = await bulletClient.getFeatureFlagValue('my_test_feature', user: user);
if (myRemoteConfig != null) {
    // run the code to use remote config value
} else {
    // run the code without remote config
}

To get the user traits for given user Identity:

var userTraits = await bulletClient.getTraits(user)
if (userTraits != null && userTraits) {
    // run the code to use user traits
} else {
    // run the code without user traits
}

To get user trait for given user Identity and specific Trait key:

var userTrait = await bulletClient.getTrait(user, 'cookies_key');
if (userTrait != null) {
    // run the code to use user trait
} else {
    // run the code without user trait
}

Or get user traits for given user Identity and specific Trait keys:

 var userTraits = await bulletClient.getTraits(user, keys: ['cookies_key', 'other_trait']);
if (userTraits != null) {
    // run the code to use user traits
} else {
    // run the code without user traits
}

To update a user trait for given user Identity:

 var userTrait = await bulletClient.getTrait(user, 'cookies_key');
if (userTrait != null) {
    // update value for user trait
    var updatedTrait = userTrait.copyWith(value: 'new value');
    Trait updated = await bulletClient.updateTrait(user, updatedTrait);
} else {
    // run the code without user trait
}

Override default configuration #

By default, the client uses the default configuration. You can override this configuration as follows:

var bulletClient = BulletTrainClient(
      config: BulletTrainConfig(
          baseURI: 'http://yoururl.com/'
      ), apiKey: 'YOUR_ENV_API_KEY');

Override the default configuration with your own:

final appDir = await getApplicationDocumentsDirectory();
await appDir.create(recursive: true);
final databasePath = join(appDir.path, 'bullt_train.db');

var bulletClient = BulletTrainClient(
      config: BulletTrainConfig(
          baseURI: 'http://yoururl.com/',
          connectTimeout: 200,
          receiveTimeout: 500,
          sendTimeout: 500,
          usePersitantStorage: true,
          persistantDatabasePath: databasePath,
      ), apiKey: 'YOUR_ENV_API_KEY');
