Our inspiration came from our first year in University, as we all lived without our parents for the first time. We had to cook and buy groceries for ourselves while trying to manage the school on top of that. More often than not, we found that the food in our fridge or pantries would go bad, while we spent money on food from fast-food restaurants. In the end, we were all eating unhealthy food while spending a ton of money and wasting way too much food.

What it does

iFridge helps you keep track of all the food you have at home. It has a built-in database of expiration dates of certain foods. Each food has a "type of food", "days to expire", "quantity", and "name" attribute. This helps the user sort their fridge items based on what they are looking for. It is also able to find recipes that match your ingredients or the foods that will expire first. It has a shopping list where you can see the food you have in a horizontal scroll. The vertical scroll on the page will show what you need to buy in a checklist format. The shopping list feature helps the user while they are shopping for groceries. No more wondering whether or not you have the ingredients for a recipe you just searched up, everything is all in one place. When the user checks a food off the list, it will ask for the quantity of the food and input it automatically into your fridge. Lastly, our input has a camera feature that allows the user scan their food into their fridge. The user can manually input it as well, however, we thought that providing a scanning function would be better.

How we built it

We built our project using flutter dart. We built-in login authentication with the use of Firebase Authentication and connected each user's food to the Cloud Firestore database. We used google photo API to take pictures for our input and scan the items in the photo into the app.

Challenges we ran into

A challenge we ran into was working with dart streams specifically so that the stream only read the current user data and added only to the current user's database. Also learning about the different Widgets, Event Loops, Futures and Async that's unique to flutter and that are new concepts was challenging but lots of fun! Another challenge we ran into was keeping track of whether the user was logged in or not. Depending on if there is an account active, the app must display different widgets to accommodate the needs of the user. This required the use of Streams to track the activity of the user. We weren't familiar with git either. So, in the beginning, a lot of work was lost because of merging problems.

Accomplishments that we're proud of

We are so proud to have a physical app that allows users create accounts and input data. This was our first time using databases (we never heard of firebase before today) and our first time using flutter. We’ve never even used github before to push and pull files. The google photo API was an enormous challenge as this was also a first for us.

What we learned

We learned a lot about flutter dart and how it works, how to implement google photo APIs, and how to access and rewrite information in a database.

What's next for iFridge

There are many features that we want to implement. This includes a healthy eating tracker that helps the user analyze what food categories they need more of. Eventually, the recipes can also cater to the likes and dislikes of the user. We also want to implement a feature that allows the user to add all the ingredients they need (ones that aren't already in their fridge) into their shopping cart. Overall we want to make our app user friendly. We don't want to over-complicate the environment, however, we want our design to be efficient and accomplish any needs of the user.
