initialize method

@override Future<void> initialize()

Initialises the provider (e.g. fetch + activate remote config).

Must be called before any getValue call.

Implementation

@override
Future<void> initialize() async {
  try {
    await _remoteConfig.setConfigSettings(
      RemoteConfigSettings(
        fetchTimeout: _fetchInterval,
        minimumFetchInterval: _minimumFetchInterval,
      ),
    );
    await _remoteConfig.fetchAndActivate();
    _lastFetchedAt = DateTime.now().toUtc();
    PrimekitLogger.info(
      'Initialised — ${_remoteConfig.getAll().length} keys loaded.',
      tag: _tag,
    );
  } on Exception catch (error, stack) {
    PrimekitLogger.error(
      'Failed to initialise Firebase Remote Config.',
      tag: _tag,
      error: error,
      stackTrace: stack,
    );
    throw ConfigurationException(
      message: 'FirebaseFlagProvider.initialize() failed: $error',
    );
  }
}
