pub package style: effective dart github stars MIT License

Research Package is a Flutter package for building research study apps on Android and iOS using Flutter.

Research Package is a Flutter implementation of the Apple ResearchKit available for iOS (just like ResearchStack is for Android). The overarching goal of ResearchPackage is to enable developers and researchers to design and build cross-platform (iOS and Android) research applications using the same codebase.

Research Package is designed from the ground up to meet the requirements of most scientific research, including capturing participant consent, extensible input tasks, and the security and privacy needs necessary for IRB approval. The main features of Research Package are:

Research Package is part of the overall Copenhagen Research Platform (CARP) with also provides a Flutter package for mobile and wearable sensing called CARP Mobile Sensing. The Pulmonary Monitor app shows how mobile sensing can be combined with collection of survey data from users.


There is a set of tutorials, describing:

The Research Package Flutter API is available (and maintained) as part of the package release at

Example Application

There is an example app which demonstrates the different features of Research Package as implemented in a Flutter app.
