Here are some thoughts 🏵️🏵️👇

1. Develop a functional-style web framework
Most web frameworks in Dart are developed using object-oriented programming techniques. However, developing a web framework based on functional programming concepts can provide benefits such as modular code, improved readability, and easier testing. Such a framework could make use of generics, lambda expressions, and streams to provide a better development experience for functional programmers.

2. Implement a distributed data processing system
Functional programming is known for its ability to process large amounts of data using parallelism. You could develop a distributed data processing system using Dart's actors and isolates APIs, allowing you to process enormous amounts of data in parallel. The use of functional programming techniques like map and reduce could also provide significant performance improvements in data processing.

3. Build a functional-style game engine
Developing a game engine using functional programming techniques could provide benefits such as improved performance, modularity, and code reusability. Game engines typically require the processing of large amounts of data and events, making them well-suited to functional programming. You could make use of Dart's Futures and Streams libraries to handle game events and the state of the game.
