I have added new entry to event log table when onBackground fetch trigger with dateTime. Smoothly it worked for some hour. but failed to continuously trigger after every 15 minutes. please review the screenshot ( it triggered from 18:43:33 to 20:15:11 )

Future initPlatformState() async { // Configure BackgroundFetch. try { var json = await read(IS_BG_FETCH_STARTED_KEY); if (json == null || json == "0") { var status = await BackgroundFetch.configure( BackgroundFetchConfig( minimumFetchInterval: 15, forceAlarmManager: true, stopOnTerminate: false, startOnBoot: true, enableHeadless: true, requiresBatteryNotLow: false, requiresCharging: false, requiresStorageNotLow: false, requiresDeviceIdle: false, requiredNetworkType: NetworkType.ANY, ), _onBackgroundFetch, _onBackgroundFetchTimeout);

print('[BackgroundFetch] configure success: $status');

doStoreEventLog( "Init Platform", "check background fetch configured or not " + DateTime.fromMillisecondsSinceEpoch( DateTime.now().millisecondsSinceEpoch) .toString());

int timestamp = DateTime.now().millisecondsSinceEpoch;

if (status == BackgroundFetch.STATUS_AVAILABLE) { doStoreEventLog( "Init Platform", DateTime.fromMillisecondsSinceEpoch(timestamp).toString() + " - " + "Background fetch configured successfully");

write( NEXT_BG_FETCH_DATE_TIME_KEY, (DateTime.now().millisecondsSinceEpoch + (1000 * 60 * 15)) .toString());

write(IS_BG_FETCH_STARTED_KEY, "1");

} else {

doStoreEventLog( "Init Platform", DateTime.fromMillisecondsSinceEpoch(timestamp).toString() + " - " + "Background fetch configuration failed " + " - " + "Status code" + status.toString()); }

} else { print('[BackgroundFetch] already configured '); int timestamp = DateTime.now().millisecondsSinceEpoch; doStoreEventLog( "Init Platform", DateTime.fromMillisecondsSinceEpoch(timestamp).toString() + " - " + "[BackgroundFetch] already configured"); } } on Exception catch (e) { print("[BackgroundFetch] configure ERROR: $e"); int timestamp = DateTime.now().millisecondsSinceEpoch; doStoreEventLog( "Init Platform", DateTime.fromMillisecondsSinceEpoch(timestamp).toString() + "|" + "[BackgroundFetch] configure ERROR: $e"); }

}

Future doStoreEventLog(String title, String body) async { var box = await Hive.openLazyBox('notificationBox'); DateTime now = DateTime.now(); String dateTime = DateFormat('yyyy-MM-dd HH:mm:ss').format(now);

EventLog eventLog = EventLog(title: title, body: body, dateTime: dateTime, isDelete: false);

await box.add(eventLog); }

void write(String key, dynamic value) { GetStorage().write(key, value); }

Future<String> read(String key) async{ return await GetStorage().read(key); }

How to restart the background fetch if not working after long period of time? can i get any log history of Background fetch callback
