Location service

Hi Team Greetings from my side 🔥🥰

Please I'm building a food delivery app and I have made a code to check if the user grant the app location so if the location permission is granted and location service is enable and this code we proceed to get the device current location and also the address but if location permission is denied this code need to get the last known location and and retrieve the address as well.. So basically retrieve the current location is working perfectly but the last known location isn't working. I mean isn't retrieving the last known located so please here is my code please help me debug or correct the code to get the last known location. Thanks in advance
