The session explores an architecture approach that separates logic into multiple independent Flutter packages that can then be imported into app-level modules as needed. This enables us to have huge code sharing between multiple end-user apps that share the same business logic and work with the same data. The best use case for this is Producer/Consumer business models that offer one app to producers and one app to consumers. Think of ride-sharing apps or event hosting and event attending apps. Listeners will know how to separate their code into a concept-level packages and create app modules that import these test-covered packages as dependencies. This enables developers to solve both the Producer/Consumer app problem as well as whitelabel app that can be customized for each client by importing only the modules that include the features the client requested.
