dart-collect-coverage

dart-collect-coverage is a skill for Claude Code, Codex from sutchan/Agent-Skills-Hub. It costs 19 tokens per session (1,182 once invoked), scanned A, a copy of dart-collect-coverage, MIT.

A Dart and Flutter testing guide that collects code coverage and produces LCOV reports. LCOV is a standard report format showing which code tests execute.

In plain words
What is it for?
Use it to configure the coverage package, run Dart or Flutter tests, apply coverage-ignore comments, and generate coverage reports.
Why use it?
It helps you measure how much of an application your tests cover and exclude deliberately untestable code from the measurement.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dart-collect-coverage scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Implementing Dart and Flutter Test Coverage

Contents

Testing Fundamentals

Structure your test suites using the standard Dart testing paradigms. Use package:test for Dart projects and flutter_test for Flutter projects.

  • Unit Tests: Verify individual functions, methods, or classes.
  • Component/Widget Tests: Verify component behavior, layout, and interaction using mock objects (package:mockito).
  • Integration Tests: Verify entire app flows on simulated or real devices.

Coverage Directives

Exclude specific lines, blocks, or entire files from coverage metrics using inline comments. Pass the --check-ignore flag during formatting to enforce these directives.

  • Ignore a single line: // coverage:ignore-line
  • Ignore a block of code: // coverage:ignore-start and // coverage:ignore-end
  • Ignore an entire file: // coverage:ignore-file

Workflow: Configuring and Generating Coverage Reports

Follow this sequential workflow to add the coverage package, execute tests, and generate an LCOV report.

Task Progress Checklist:

  • 1. Add coverage as a dev_dependency.
  • 2. Execute the automated coverage script.
  • 3. Validate the LCOV output.

1. Add Dependencies

Add the coverage package as a dev_dependency to your project. Do not add it to standard dependencies.

If working in a standard Dart project:

dart pub add dev:coverage

If working in a Flutter project:

flutter pub add dev:coverage

2. Collect Coverage and Generate LCOV

Use the bundled test_with_coverage script. This script automatically runs all tests, collects the JSON coverage data from the Dart VM, and formats it into an LCOV report.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
