flutter-dart

What problem does it solve?

This hub helps Flutter developers manage Dart's async primitives, null safety, and immutable data patterns to prevent common bugs such as setState after dispose, stale results, and jank from CPU-heavy work.

Core Features & Use Cases

• Async correctness: manage Futures/Streams with cancellation and timeouts.
• Null safety & immutability: model data safely at boundaries and propagate non-null types.
• Isolates & off-main-thread work: move CPU-intensive tasks away from UI thread.
• Defensive patterns: cancel or ignore stale async results to prevent UI flicker.

Quick Start

Implement a small Flutter example that uses an owner and a generation counter to cancel or ignore stale async responses.
