dart3-idioms-and-coding-standards
Enforces which Dart 3 construct each declaration earns — sealed class + exhaustive switch with no `default:`/`case _:`, the three class modifiers (`sealed`/`final`/`abstract interface class`) and skip the rest, records as intra-layer tuples only, immutable value types (`final` fields, `const` ctor, value equality) hand-rolled when trivial and `freezed` when boilerplate dominates, explicit stable identity, total non-throwing domain functions, make-illegal-states-unrepresentable, and firm method/build/file/nesting complexity limits (the single-source-of-truth table other skills cite) — while ban
Why this score
This repo hosts 10 skills, so its 58 stars are split between them (about 6 each) for scoring.
Popularity score: 53/100 from public GitHub signals only. It shows how widely used and maintained this is, not how well it works. Not included yet: the fake-star check. The security scan is shown separately and doesn't change the score. How we rank
Security
Scanned Oct 20, 2026 at commit e073e5ea10c9, with Cisco's open-source skill-scanner.
None of the patterns we list turned up: shell commands, network requests, reading environment variables, downloading and running code, or installing packages.
A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
