Fix a bug - Flutter, Dart project

Background: Looking for someone to fix a bug in a flutter app. Its an e-commerce app driven by APIs, there is no backend processing within the app as it uses API endpoints. Bug: The functionality to checkout an order is handled by several endpoints such as: 1. /create-basket/ 2. /add-product-to-basket/[id] 3. /retrieve-basket/ 4. /checkout-basket/ My understanding is that there is an issue when checkout is done by unauthenticated user. The /retrieve-basket/ endpoint is not working as expected when hit in flutter app. This functionality works just fine if you do it in the browser or in postman, this is because the browser handles the cookies automatically so the backend knows which basket to retrieve. The fix for this bug would be to handle the cookies issue within the flutter app so that the backend is able to retrieve the correct basket for unauthenticated users
