Interexy’s experience in Flutter Development


The Parsl is a solution for managing cannabis compliance and regulation enforcement.


Develop a stable mobile solution for existing SaaS web-based products to automate logistics & items scanning activities for employees in cannabis businesses.


The main challenge was to integrate the application with complex backend infrastructure and establish a seamless workflow using Flutter – we had to automate scanning activities and thus worked heavily with background threading, main UI thread & local memory a lot.


The application was developed successfully & is live on the marketplace – it’s already being used in cannabis businesses across the West Coast.

Our goal was to develop an easy-to-use mobile application with a seamless user experience for the existing and already popular web product.


Labster had an existing web-based products and tight time-frames outlined by the investors to develop MVP of the app using complex Unity integrations with new-born app development technology – Flutter.


The app was developed and successfully launched into the Google Play Market – it has 100,000+ users and counting!
