Closing Thoughts

This tutorial should get you started with a basic understanding of the flow of a ratatui program. However, this is only one way to create a ratatui application. Because ratatui is relatively low level compared to other UI frameworks, almost any application model can be implemented. You can explore more of these in Concepts: Application Patterns and get some inspiration for what model will work best for your application.
