Food Delivery Price Comparison - DingDong!

The page where a user enters the address for delivery.
The user enters the quantity of the item.
Here, the list of menu items for a restaurant and the user picks the items.
This is the page where users see all the restaurants by the address they entered.

**OUR PROJECT IS NOT COMPLETE*

Inspiration

Due to the pandemic, lots of people order in food instead of going to restaurant to be safe. There are many popular food delivery applications available and for a lot of people, they scroll through multiple apps to search for the cheapest price for the same items. It is always nice to save money and our app can definitely help people with this.

Our proof-of-concept application utilizes dummy data from our own database. The reason for this is because there is a lack of publicly available APIs to gather food delivery company information that is required.

What it does

The user enters in a delivery address, and this gets a list of restaurants. Then, the user selects a restaurant, selects the menu items and the quantity of each item, and then they will be able to see a price breakdown and the price total between the available food delivery services.

How We built it

We decided to create a Flutter application to challenge ourselves. None of us had worked with Flutter and the Dart language before and this was a fun and difficult process. 3 of us developed the frontend.

The backend was created using Express.js, database using Google Cloud SQL, and the server hosted on Heroku. 1 of us developed the backend (which was amazing!)

Challenges We ran into

As we are all unfamiliar with Dart and Flutter, it took us more time than with a familiar tool to develop. The time pressure of the hackathon was also a challenge. Although we didn't finish on time, this was still nonetheless a wonderful experience to develop something cool with a new technology.

Accomplishments that We're proud of

We are proud to learn a bit about Dart and Flutter, and to be able to develop for most of the hackathon. We accomplished a lot but if we had more time, we could have finished the project.

What I learned

Dart and Flutter. Working with API calls in Dart.

What's next for our App

There are a few features in the roadmap, if we were to continue working on this app we would:

add promotions. This is a key feature because the price between the services vary greatly if promotions are taken into account
add login functionality
web scrape (or find publicly available APIs) popular food delivery services and obtain real data to utiilize
add images to restaurants and menu items

Created by

I worked on the frontend: the page to enter the user and the page to display restaurants. I also wrote the data object classes to represent the database objects.

I worked on the backend server API routes and the database. The database was hosted on Google Cloud SQL and the API was hosted on Heroku.

Alex Hsieh
I worked on the front-end. It was my first time using flutter. I learned a lot.

Joshua Kim
I worked on the front-end, I have minimum experience working with Javascript/Vue.js/React. So, when we first start working with flutter I was very lost. Overall, it was a good experience because I learned a lot about flutter over the last 24 hours. I plan on using Flutter as the frontend for my next personal project.
