Varioqub Configs

Flutter plugin providing work with remote configs, experiments and A/B testing via Varioqub.

Example of using

// Initializing Varioqub
await Varioqub.build(
    const VarioqubSettings(
      clientId: _clientId,
    ),
);

/// Activation of previous configs.
/// It is recommended to activate the configuration during application startup.
await Varioqub.activateConfig();

/// Extracting configs from Varioqub.
/// It is recommended to fetch the configuration during the application without waiting.
await Varioqub.fetchConfig();

/// Getting the config by "FLAG" key.
await Varioqub.getString(
    key: 'FLAG',
    defaultValue: 'DEFAULT_VALUE',
);

Using together / without AppMetrica

Using the library together with AppMetrica is only available using the appmetrica_plugin library version higher than 2.0.0.

To use experiments and analytics to get configs, use the following build configuration:

await AppMetrica.activate(const AppMetricaConfig(_appMetricaKey));

// Initializing Varioqub
await Varioqub.build(
    const VarioqubSettings(
        clientId: _clientId,
        // The use of this flag is mandatory after initialization of AppMetrica
        trackingWithAppMetrica: true,
    ),
);

Request throttled exception

This exception, as well as other exceptions, can be received during fetchConfig execution. Expect them when getting the config as follows:

try {
    await Varioqub.fetchConfig();
} on VarioqubFetchException catch (exception) {
    if (exception.error == VarioqubFetchError.requestThrottled) {
        debugPrint('Request has been throttled');
    } else {
        rethrow;
    }
}

Request throttled means that the timeout for the refetch request did not occur and the current request was canceled. If you want to change the fetch time, use fetchThrottleIntervalMs in build method.
