Flutter : Run an app as a background service
I want to show a custom popup message whenever the user disconnects a cellular call. The problem is how to detect when the app is not running. any leads would be helpful.
Solution 1:
It's been a while and there have been many developments.
First, there are some answers at How to create a service in Flutter to make an app to run always in background?
Also, flutter/Background processes will basically point you to medium/Executing Dart in the Background with Flutter Plugins and Geofencing (Sept 2018)
- which is a Geofencing sample that involves a partnership between isolates, native Android/iOS code via
MethodChannel, andPluginUtilities.getCallbackHandle(PluginUtilities)
Alas, there are many plugins available now:
