CARP Study Generator Utility Package #

This utility package helps generate the configuration files needed for a CARP Mobile Sensing study, and uploading this to the CARP web server.

Configuration and Setup #

To use the study generator, do the following in you app:

1. Include carp_study_generator and test as part of the dev_dependencies in the pubspec.yaml file.
2. Copy the folder carp to the root of you project.
3. Configure carp.yaml, and the json files protocol.json, consent.json, and the language json files (en.json, etc.).

File Structure #

All files used for creating and uploading configurations to CARP is stored in the carp folder in the root of your (app) project file. The name of the json files to upload is specified in the carp.yaml file.

Please ignore the test scripts in the carp folder (these are used to execute the commands).

Each command is run like this:

  flutter test carp/<command>

The available commands are:

  help           Prints this help message.
  dryrun         Makes a dryrun testing access to the CARP server, and the protocol, consent, and localizations.
  protocol       Create a study protocol based on the file 'protocol.json' and uploads it to the CARP server.
  consent        Create an informed consent based on the file 'consent.json' and uploads it to the CARP server.
