Background Info
The app must be able to take pictures from the rear camera. These pictures must be saved temporarily in the phone's cache somewhere so that it can be funneled into the waste recognition API (to be announced when that is made).

The idea is that the user will be able to take a picture and the waste recog. API can tell the user how to dispose of the waste correctly.

In short, this feature has not been implemented yet... all it does now is activate the phone's rear camera. Should be a decent sized project as it is a very important feature that needs to be implemented correctly.

Bug 1
Right now, the camera API is buggy and can only be used once. If the user swipes to a different screen then back, the camera will be off (shows a black screen).

Bug 2
The image the camera displays before the user takes a photo is stretched.

Please let me know if you have any questions.

See the second screen of this flow chart.

Right now, clicking tools will just open the camera. We want to be able to click to toggle a hamburger that lets the user choose between "Nearest Bins" (map feature) or "Waste Recognition" (the camera).

Right now only dummy data is displayed (it's all hard coded). We should leverage the fact that the web app and mobile app are both connected to an expressJS backend. That expressJS backend will handle all of the API calls to TIPPERS.

Here are your assigned action items for this week. Let me know if you need more time since midterms are starting soon.

1. Follow the onboarding guide and this repo's readme... Get the mobile app running (would be nice if you could figure out the dependency issues and how to resolve the risks... I have some of them mitigated)
2. As one of our few iPhone users, please see if you can get the Expo app to run on your iPhone. How is the performance on it?
3. Is there a way to emulate iPhone devices and not just Android devices?
4. I think we should just stick with React Native. I think it's good enough for our use case since we only need to leverage the device's camera and GPS APIs. What do you think?

Deadline: Next subgroup meeting

1. Scan the barcode number through camera. (#4):
2. Send the barcode number to the barcode API
3. Notify user of information retrieved (has this been designed yet? maybe a pop up with the name of item, and how to properly dispose of it)

Since we are leveraging Expo's many libraries, we are able to access the expo-camera library. See how we are using that API here: (#1)

Another very useful feature expo-camera has is the ability to scan barcode in the camera frame, without taking a picture. This should be connected to the barcode scanner API. See the expo-camera documentation here: (https://docs.expo.io/versions/latest/sdk/camera/)

I would particularly look at "onBarCodeScanned", "onBarCodeRead".
