I want to perform a task in which my app send location details in every 30 minute to the server.I want to do this using flutter. This process would continue even after if App is in close state.

I tried some code,but i didn't find any flutter plugin for background service.I search on google about this,then i got that i have to write native code for both android and ios platform that is the main problem.I can write code for android only not for ios.
Please guide me how to overcome this problem.
thankyou,
