WzSayEz

Inspiration

Many a time, many Singaporeans, just like us, do feel the urge to recycle and help the environment out. With so much help given to conventional recycling ways, recycling of electronics are often left out, or unknown to many.

What it does

App to allow users to recycle any items, with a map of all e-recycling bins integrated into it. Users are able to send in their photos/pictures to be stored in our database, and be awarded points when they are approved by the system administrators.

How we built it

Using Flutter, which is a cross-platform app development tool, we built the app with dart as the main programming language used.

Challenges we ran into

Incomplete/ missing data from API Requests. Problems with CSV format. Reducing the loading time for markers to be drawn on the map.

Accomplishments that we're proud of

Reducing the loading time for markers to be shown on the map, from over a minute to instantaneously, but precomputing the data once beforehand.

What we learned

Reducing lag time by precomputing certain values once at the start.
