Design and debug Dart asynchronous infrastructure with Future, Stream, isolates, cancellation, and lifecycle-safe ownership. Use for races, stale results, background CPU work, stream leaks, or async error handling; not for routine form-local validation or submission unless its underlying ordering mechanism is the task.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Dart Concurrency Make ownership, ordering, cancellation, and error propagation explicit. ## Diagnose first Identify the producer, consumer, lifecycle owner, ordering requirement, and desired behavior when work becomes obsolete. Reproduce the race or leak before adding synchronization-like machinery. ## Decision rules - Use `Future` for one result and `Stream` for a sequence over time. - Avoid unawaited work unless independence and error handling are intentional. - Cancel subscriptions and controllers according to the owning object's lifecycle. - Guard UI updates after async gaps with the lifecycle mechanism appropriate to the project. - Prevent stale requests from overwriting newer state through cancellation, tokens, sequencing, or latest-wins logic. - Use isolates for measured CPU-bound work or isolation needs, not ordinary network I/O. - Send transferable values across isolate boundaries and surface failures to the caller. - Preserve stack traces when translating errors. Do not hide async ownership inside global helpers. Keep retry and timeout policy at a boundary that understands idempotency and user intent. ## Verification …

How to install
mdr add thiennc-tesoglobal/flutter-skills/dart-concurrency@sha256:90b6a3305c53f103The line at the top of this page pins the label git:20260904.d6e468f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
