+description: An example app using drift in a Flutter app 
+
+---
+
+For a comprehensive example of a cross-platform Flutter app that incorporates drift and follows best practices, refer to the [app example](https://github.com/simolus3/drift/tree/develop/examples/app) in drift's repository.  
+
+This example serves as an excellent starting point for users interested in exploring how to integrate drift into a Flutter app with a modern architecture.
