How to create or develop a mock location using flutter framework what should i need to know? Is there any plugins already exist which will give me a random location or fake gps? I searched i find some mock location detector which will detect my locations not providing them.

I want to build an food delivery app which will alows me to show location but not the current location,I need fake location or gps.
For this, should i get help from third party sites to get fake gps or is there any existing plugins which will provide me fake location or gps
