time method

@override void time(String key)

自定义测速打点上报，需要和timeEnd配合使用 time('customTime');

Implementation

@override
void time(String key) {
  if (_timeMap[key] == null) {
    _timeMap[key] = DateTime.now().millisecondsSinceEpoch;
  } else {
    developer.log('[time] report time key exist',
        name: debugLogType.critical);
  }
}
