storehound

Catch App Store and Google Play rejections in your Flutter project before you upload: one Dart command lints Info.plist, the privacy manifest, entitlements and AndroidManifest.xml, and fails CI on the mistakes that get builds refused.

Why

• A missing purpose string or a privacy manifest that never reaches the bundle compiles, passes every test, and only shows up as an ITMS- email after upload.
• A vague purpose string or an unjustified background mode costs you a whole review cycle.
• Play refuses an update below the target API deadline, usually during an urgent fix.

It reads the files you ship and answers in about a second. No Xcode, no macOS runner, no build.

Install

dart pub global activate storehound

Or pin it per project with flutter pub add --dev storehound and run dart run storehound.

Coming from imaji_store_preflight

This package was renamed. Replace imaji_store_preflight with storehound in dev_dependencies (or dart pub global activate storehound), run storehound instead of imaji_store_preflight, and rename imaji_store_preflight.yaml to storehound.yaml. Rules and options are unchanged.

Quick start

cd my_flutter_app
storehound

If ~/.pub-cache/bin is not on your PATH, run dart pub global run storehound. Exit code 0 means clean, 1 means findings at or above --fail-on (default error), 2 means a usage or configuration problem.

Example output

A fresh flutter create app gets one warning: no privacy manifest yet. Here it is after flutter pub add image_picker and a one-line camera purpose string (--brief drops the why/fix text):

$ storehound --brief
privacy-manifest-present — The app target ships a PrivacyInfo.xcprivacy
  warning  ios/Runner/Info.plist
    No privacy manifest at ios/Runner/PrivacyInfo.xcprivacy (or the path
    configured under `paths.privacy_manifest`).

purpose-string-missing — Linked plugins have the purpose strings they need
  error  ios/Runner/Info.plist
    `NSPhotoLibraryUsageDescription` is missing, but image_picker needs it.
  warning  ios/Runner/Info.plist
    `NSMicrophoneUsageDescription` is missing; image_picker needs it only if you
    record video (image_picker README, "iOS").

purpose-string-quality — Purpose strings name a feature and give an example, not restate the permission
  error  ios/Runner/Info.plist:5
    `NSCameraUsageDescription` only restates the permission; name the feature
    that uses it and give an example. Current text: "This app needs camera
    access."

✗ 15 rules checked: 2 errors, 2 warnings, 0 info. Failing: findings at or above `error`.

A key a plugin needs in every app is an error; a key its README asks for only when you use one feature, like the microphone for recording video, is a warning that names the feature. The exit code is 1, so CI fails. Without --brief each finding also says why it matters, how to fix it, and links Apple's or Google's documentation. --format json and --sarif give the same findings in machine-readable form.

Run it in CI

This job fails the build on errors and shows each finding as a code scanning annotation on the pull request:

name: Store preflight
on: [push, pull_request]

jobs:
  preflight:
    runs-on: ubuntu-latest
    permissions:
      contents: read
      security-events: write   # upload SARIF
    steps:
      - uses: actions/checkout@v6
      - uses: dart-lang/setup-dart@v1
      - run: dart pub global activate storehound '^0.2.0'
      - run: dart pub global run storehound --sarif --output preflight.sarif
      - uses: github/codeql-action/upload-sarif@v4
        if: always()           # upload even when the check fails the job
        with:
          sarif_file: preflight.sarif
          category: storehound

No macOS runner needed. Code scanning needs a public repository or GitHub Advanced Security; without it, drop the upload step and read the text output in the job log. More on CI, including how android-target-sdk behaves on a Dart-only runner.

What it checks

Rule	Catches
purpose-string-missing	ITMS-90683 "Missing purpose string" for plugins like image_picker, camera, geolocator
purpose-string-quality	Guideline 5.1.1(ii): a purpose string that only restates the permission
privacy-manifest-present	ITMS-91053: no PrivacyInfo.xcprivacy, or one missing from Copy Bundle Resources
privacy-manifest-values	Data types, purposes and reason codes that are not Apple's exact values
privacy-manifest-tracking	NSPrivacyTracking contradicting the entries or tracking domains
privacy-manifest-sdk-data	"Collects nothing" while Firebase, AdMob, Sentry or another known SDK is linked
tracking-usage-description	"Add for Review" refused over NSUserTrackingUsageDescription vs declared tracking
background-modes-justified	Guideline 2.5.4: background modes with no feature behind them
push-entitlement	Push SDK linked without aps-environment, so notifications never arrive
export-options-build-number	Xcode silently bumping CFBundleVersion at export
bundle-localizations	CFBundleLocalizations out of sync with your ARB locales
android-target-sdk	targetSdk below Google Play's current deadline
android-16kb-page-size	A build toolchain without 16 KB page-size support
android-picker-queries	file_picker without an OPEN_DOCUMENT <queries> entry
unreadable-file	A config file that does not parse, so rules would silently pass

storehound --explain <rule-id> prints the full why, fix, options and documentation links for one rule.

Your own checks

Pins only your app cares about go under checks: in storehound.yaml, each with a reason, and are reported like any rule as check:<name>:

checks:
  no-backup:
    file: android_manifest
    element: application
    attribute: android:allowBackup
    equals: "false"
    reason: "Tokens live in shared preferences."

They work on Info.plist keys and AndroidManifest.xml attributes; see Project checks for the operators.

Is it noisy on a real app?

It should not be. CI runs it with --fail-on info on a production-shaped fixture (two flavors, SwiftPM only, AGP 9, separate Debug and Release entitlements, a large commented Info.plist) and expects no findings at all, and the tests change one thing at a time in it to check that each mistake is still caught. If it reports something on your app that is not a real problem, please open an issue with an anonymised copy of the lines involved.

Contributing

The most useful contributions are a rejection you hit that no rule catches (open an issue with the anonymised reviewer wording or ITMS- code and the public Apple or Google documentation) and corrections to the data tables. CONTRIBUTING.md explains how to add a rule; issues labelled good first issue are a good place to start. Questions and ideas that are not bugs go to Discussions.
