The CARP Mobile Sensing App provides an example on how to use the carp_mobile_sensing package. The app sets up a Study that starts a set of Probes, which collects the data.
The UI of the app is shown below, showing the Study Visualization page and the Probe List page.
The Github page contains a detailed description on how this app is constructed (using the BloC software architecture) and the CAMS code behind it. If you’re interested in building a Flutter app using CAMS, there is a tutorial on how to get started.
