Flutter app architecture and Windows installer delivery skill: Riverpod 3 codegen, Freezed sealed classes, GoRouter typed-route SSOT, Hive CE persistence, privacy-safe Crashlytics/Sentry reporting, gen-l10n, and verify-before-publish Inno pipelines.

Compatibility: Not stated.

Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED INSTALL_DOCUMENTED_INSTALLER

Why this grade

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    .agents/skills/building-flutter-apps/references/state-management/async-mutations.md, line 92 final page = await ref.read(productRepositoryProvider).fetch(cursor: state.cursor);

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .hooks/ship_actions.py, line 95 Path(name).name.startswith(".env")

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    tool/check_windows_installer_inputs.py, line 79 result = subprocess.run(

  • INSTALL_DOCUMENTED_INSTALLER Note

    Documentation shows an installer that pipes a download into a shell.

    AGENTS.md, line 6 - No status → from repo root: `curl -fsSL https://raw.githubusercontent.com/sgaabdu4/hard-eng/main/setup.sh | sh` (prepares that branch).

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.

Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.

What was checked

Plain notes from the hygiene checks.

  • Install and update

    Note

    The docs document an installer that pipes a download into a shell.

    INSTALL_DOCUMENTED_INSTALLER

    AGENTS.md, line 6

  • Network

    Concern

    can reach a host that is not written as a fixed address.

  • Secrets

    Concern
