Firebase Backend
Package carp_firebase_backend
Code backends/carp_firebase_backend

A Flutter plugin for uploading data from the CARP Mobile Sensing Framework to a Google Firebase data backend.

Supports uploading json to Firebase as either (zipped) files to Firebase Storage or as plain json to a Firebase Database.

This package can upload sending data to Goggle Firebase in two ways:

  • Google Firebase Storage – By using the Google Firebase Storage endpoint, CARP sensing data are uploaded as raw or zipped JSON file, generated using the FileDataManager in carp_mobile_sensing. In Firebase, files with sensed data is stored in the path specified in the FirebaseStorageDataEndPoint plus subfolders for each study and device. The path on Firebase hence follow this pattern: /<path>/<study_id>/<device_id>/

  • Google Firebase Database – By using the Google Firebase Database endpoint, CARP sensing data are uploaded as raw JSON data points, using Firebase as a DataManager in carp_mobile_sensing. In Firebase, data json objects are stores in the collection specified in the FirebaseDatabaseDataManager. JSON objects will be stored in collections named /<collection>/<study_id>/<device_id>/upload/<data_type> relative to this path. For example, if collection is carp_data, study_id is 1234 and device_id is R16NW, location data will be stored as documents in this collection: carp_data/1234/R16NW/upload/location.
