Notification System of Dangerous Incidents to User

[yaswant2403]

Features

• Users get notifications of the incidents closest (within a set radius) to their current location that have high severity and happened within the past 6 hours.
• When the user clicks on the notification, take them to the corresponding Marker

Setup

The eas-config branch has the example code for setting up a basic push notification system. In order to run it yourself,
you need to follow the below steps:

1. Make an account on https://expo.dev/ and DM me your email that you registered with so I can add you to the organization. You should be able to access https://expo.dev/accounts/fa24-group21/projects/SafeIllini after you've been added.
2. npm install -g eas-cli
3. eas -v (verfiy eas has been installed)
4. eas login with expo account details
5. eas whoami (verify your account is outputted)

Then, you should be able to run npx expo start regularly to launch the app and test out the push notifications. If you want to see how the eas-config branch merges into the main branch code, you can check out the main branch. However, the main branch still doesn't integrate the notifications with the incidents. That will be your task.
