Build a reactive Flutter App
summary
Shows how to structure Flutter apps with language‑level Streams, using async star functions and yield for streaming results, and adding operators and subjects with RxDart publish subject. Demonstrates a concrete counter: a subject receives taps, a scan accumulator produces an integer stream, and a StreamBuilder renders updates. Tests assert the exact emitted sequence and error cases. Claims 50–60% code reuse across Flutter and AngularDart and emphasizes closing controllers to avoid leaks.
