Build flutter mobile app UI for food ordering.

We have an app already written in flutter. We want you to write food menu and order page for this app. The Food menu is already in our firebase database, you need to visit database to get those data and display to the page accordingly. There is a local cart, user can add food to cart thru menu page, and it will be store locally on phone until user cancel it or purchase it. Only one restaurant can be in cart one time, meaning if user add other restaurant then, it will pop an dialog for user to confirm delete food in cart. ##Update: In menu, customer will be able to search and filter the menu items. Implementation will use algolia We will provide algolia account have all searchable indice. We will handle payment, whatever after proceed to checkout. Basically, you will need to be good on flutter UI design, and knows how to get data from firebase firestore. Required pattern and UI library is listed in requirement. There will be no back-end need for your work, we will have dev to support rest-api, if any needed. More detail info such as UI design detail, and database schema will be provided after you accept and started. Budget: $500 Scope: Build app page as we described in our document, most work is UI/UX implementation. We will have dev to provide what the integration interface is needed. Maintain for 7 days after final code delivered, just for minor code change, guarantee no design change. Review will be done only after maintenance period. Three milestones named, source code need to submit for our developer to review, to see if it’s good for integration, before the milestone confirm. #requirements • Flutter source code, firebase firestore, BLoC. • Flutter version lastest, app for both android and IOS iphone • [login to view URL] Use this pattern for all BLoC • Cart obj • Sqlite to store cart obj • Function to convert SQLite data back to cart obj • UI must follow UI design guideline. • Algolia flutter sdk, using [login to view URL]
