 * By default, data logged to Braze through the SDK is queued locally and sent to Braze's servers asynchronously on a
 * regular interval. This is done to optimize network usage and provide resiliency against network or server outages.
 * This method bypasses the interval and immediately flushes queued data.
 *
 * @param callback - Invoked when the flush completes with a boolean parameter that indicates
 *   whether or not the flush was successful. If the flush is unsuccessful, pending data will be
 *   flushed during the next successful flush.
