foreground_service (Flutter v.1.12.x or later)
Create Android foreground service/notification
Prep (Android side):
Android foreground services require a notification to be displayed,
and notifications require an icon.
For this plugin to work, the icon needs to be in this specific location:
res/drawable/org_thebus_foregroundserviceplugin_notificationicon
(take a look at the /example app if you're confused)
-- NOTE FOR PLUGIN VERSION 2.0.0 and above --
compileSdkVersion & targetSdkVersion need to be 29 or above, or the build will fail
these values are set/can be changed in the build.gradle for the app
Use (Flutter/Dart side):
To start the service, call ForegroundService.startForegroundService([serviceFunction])
serviceFunction will then be executed periodically, but "minimum/best-effort"
i.e. it will try to make the interval between function executions *at least* that long
Doesn't work?
As long as you're calling ForegroundService.startForegroundService,
"flutter run" should show error messages that indicate what's wrong/missing
i.e. messages beginning with E/ForegroundServicePlugin indicate an error from the plugin
Caution:
ForegroundService.notification.get* methods may give unexpected values.
Once notifications are sent out, there's no way to retrieve the "current" data.
To work around this, the plugin keeps a version of the notification around.
This version may not have been "sent out" yet, however.
Disclaimer:
Most of the fancy stuff is shamelessly pilfered from the android_alarm_manager plugin
