问题 I am looking for a solution to get the user's location in a specific time-interval in Android API 17 (Android 4.2) and when the phone is locked.

At first I had some pretty basic code, which worked very well when the

问题 Problem I am building an application that requires some of the functionality of the Radar.io SDK, and so I decided to create plugin so after this project is over I can share the plugin with the rest of the Flutter Community. The problem is, I am not able to receive events in this plugin. This is important for the plugin since in order to receive events such as geolocation triggers and other background events this receiver needs to be receiving realtime information. I have successfully
