I am run flutter old project with flutter SDK : 2.5.0 ,
there is no any error (syntax error), but when i was run i got Error

I would like to create a service that will run in the background and whose purpose is to detect a ShakeDetector event (check if the User shakes his phone). After detecting the “Shake” event, I’d like to launch the application on a specific page. But I’m having trouble with the context not being valid in a service.
what to do please.
thanks in advance

I have read some tutorials about background with flutter: background_fetch, workmanager and so on.
Their all have the issue that the minimum frequency is 15minutes.
That don’t even fullfil the requirements of many application. Spotify runs for hours in the back, as well as youtube or the simple preinstalled countdown app/timer app on my samsung galaxy.
I would have assumed that the Flutter team should have a basic feature or package for background task since it is a very common feature.
