Ship checklist: mobile Flutter app built with AI assistance

You've built a Flutter app with Cursor and Claude in a few weeks. It works on your machine, your phone, and maybe a friend's device. Now you need to ship it to real users, and suddenly you realize you don't know what you don't know. The gap between working code and production-ready software is where most AI-built projects stall. This checklist closes that gap by walking you through the exact steps, tools, and workflows to ship a Flutter app that won't fall over on launch day.

TL;DR: Shipping a Flutter app requires testing across devices, hardening security, optimizing performance, and setting up deployment pipelines before you go live. Use this checklist to audit your app for common weak points, configure signing and release builds, and automate deployment to Google Play and the App Store. Most AI-built Flutter apps fail because they skip testing and security, don't be that project.

You've probably heard that AI can build anything now. That's true for the happy path, the sunny day scenario where everything works as expected. But real users aren't on the happy path. They're on slow networks, old phones, screens in bright sunlight, and with one eye on the battery indicator. They're also the ones who'll find security holes, crash the app with unexpected input, and leave one-star reviews if the app doesn't load.

Building with AI is fast. Shipping is the hard part. The good news: shipping is learnable, repeatable, and automatable. This resource gives you the exact checklist to move from "works on my machine" to "shipped to thousands of users."

Why AI-built apps often fail at launch

AI excels at writing features. It struggles with the invisible work: testing, security, performance, and deployment. When you're iterating on a prototype, you can skip these. When you're shipping to users, you can't.

The most common failure points:

• No automated testing. The app works in dev mode. It crashes in release mode because AI didn't catch a threading issue or a null pointer.
• Hardcoded secrets. API keys, database credentials, or Firebase configs baked into the code. One reverse engineer finds your backend.
• No performance profiling. The app runs fine on your phone, a flagship with 8GB of RAM. It hangs on devices with 2GB, killing your App Store rating.
• Missing permissions and privacy. Users can't upload photos because you never requested camera permissions. GDPR fines because you didn't document data collection.
• No CI/CD pipeline. Every build is manual, error-prone, and takes 45 minutes. You can't ship bug fixes quickly.
• Version management chaos. You don't know which version is live, which version has which bug, or how to roll back.

Although building software is easier than ever, most AI projects still stall halfway through."

These aren't mysterious. They're just things that nobody told you to check.

Step 1: Audit your code for common weak points

Before you can ship, you need to know what you're shipping. Run a quick audit against this list:

• Are API keys, database URLs, or Firebase credentials in your code or config files? Move them to environment variables or a secrets manager (like GitHub Secrets if you're using GitHub Actions, or Firebase Remote Config for runtime config).
• Does your app talk to a backend? Is the connection encrypted (HTTPS/TLS)? Is request validation happening server-side, not client-side?
• Are you handling user input safely? Is there any SQL injection risk? Are you sanitizing strings before displaying them?
• If you're using third-party packages, run flutter pub outdated and check for known vulnerabilities via the Dart security advisory database.

• Does the app have any obvious memory leaks? Build in profile mode and use DevTools to check heap size growth over time. If it keeps climbing, you have a leak.
• Are you loading large images without resizing? Images are the #1 killer of app performance.
• Are network requests happening on the main thread? If so, the UI will freeze while waiting for data.

• Does the app handle network failures? What happens if the user goes offline mid-request?
• Do all user-facing screens handle empty states (no data, loading, error)?
• Have you tested on a real device, not just the emulator?

Step 2: Set up testing before you ship

You don't need 100% test coverage. You need tests for the things that matter: critical user flows, API calls, and any custom logic.

Unit tests catch logic bugs. Test your business logic, data models, and utility functions. These are fast and should pass in seconds. Add them in test/ directories using the test package.

Widget tests catch UI bugs. Test that buttons do what they're supposed to do, that forms validate input, that navigation works. Add these in test/ directories using the testWidgets function.

Integration tests catch end-to-end problems. Test the full flow: user logs in, uploads data, sees results, logs out. Run these on a real device or emulator. They're slow but catch integration issues AI missed. Put these in integration_test/.

Start with one integration test of your core user flow. Just one. That catches 80% of the disasters.

Run tests in CI/CD so they fail automatically before code goes to production. Use GitHub Actions (free if your repo is public) or Firebase Test Lab (paid, but reliable) to run tests on real devices before each release.

Step 3: Optimize performance and size

Mobile users expect apps to launch in under 2 seconds. If yours takes longer, they'll uninstall before it finishes loading.

Size matters. Each megabyte of app size costs you downloads. Aim for under 50 MB if you can, under 100 MB maximum. Use flutter build apk --split-per-abi to generate separate APKs for ARM64 and ARM32 (smaller download, same code).

Images are the problem. Use tools like ImageMagick or online services to compress images before adding them to your project. Serve images in WebP format when possible (smaller than PNG/JPG). On-device, use Image.network with caching instead of bundling large images.

Profile on real devices. Use Flutter DevTools to profile your app on an old phone with limited RAM. If it's sluggish, use the performance tab to find the bottleneck, usually a rebuild that shouldn't happen or a network call on the main thread.

Lazy load data. Don't fetch all data on startup. Load what the user needs now, fetch the rest in the background.

Step 4: Prepare for deployment

Deployment to the App Store and Google Play each have their own requirements. You need signing certificates, app IDs, privacy policies, and screenshots. Start this work early, getting approval from app stores can take time.

• Generate a keystore file: keytool -genkey -v -keystore ~/my-release-key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias my-key
• Store the keystore password and key password somewhere safe (not in git).
• Configure signing in android/app/build.gradle to use the keystore for release builds.
• Build a release APK: flutter build apk --release
• Test the release build on a real device before uploading. This is critical. Release mode behaves differently from debug mode.
• Upload to Google Play Console. You'll need a Google Play Developer account ($25, one-time).

• Get an Apple Developer account ($99/year).
• Generate an App ID and provisioning profile in Apple Developer.
• In Xcode, configure signing and capabilities.
• Build for release: flutter build ipa --release
• Test the build on a physical iPhone or iPad. The simulator doesn't catch everything.
• Upload to App Store Connect and submit for review.

• Write a privacy policy (use a tool like iubenda or write one yourself). Link it in your app settings.
• Create app screenshots and descriptions for each store.
• Version your app. Start at 1.0.0 and increment: 1.0.1 for bug fixes, 1.1.0 for features, 2.0.0 for major changes.
• Don't ship version 1.0.0 with critical bugs. Test thoroughly before that version lands.

Step 5: Build a CI/CD pipeline

CI/CD (Continuous Integration / Continuous Deployment) automates testing and building so you don't have to remember 47 manual steps every time you ship.

GitHub Actions example workflow (save as .github/workflows/flutter-release.yml):

name: Flutter Build & Test

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
uses: actions/checkout@v3
uses: subosito/flutter-action@v2
run: flutter pub get
run: flutter analyze
run: flutter test
run: flutter build apk --release

This workflow runs every time you push to main. It installs Flutter, runs tests, checks for code issues, and builds an APK. If anything fails, the build fails and you know before users see the broken code.

Secrets for deployment: If you want to fully automate deployment to Google Play, store your keystore file as a GitHub Secret and reference it in your workflow. Same for iOS signing. This is advanced but saves hours every release.

Interactive: Pre-launch readiness tracker

Here's a visual tracker to monitor your app's readiness across key areas before launch:

This tracker is an example of what your pre-launch checklist might look like. Copy this template and fill in the current status of each area in your project. Aim to move everything to "Ready" before you submit to the App Store or Google Play.

Common mistakes to avoid

Shipping too early. Just because the app works doesn't mean it's ready. Release mode, real devices, and stress testing are non-negotiable. AI-built apps fail at scale because they weren't stress-tested.

Forgetting permissions. Your app will crash if it tries to access the camera, microphone, or files without requesting permission first. Test every permission path.

Ignoring platform differences. iOS and Android are not the same. The back button, navigation patterns, and permissions model differ. Test on both.

No monitoring. You shipped it. Now you need to know if users can actually use it. Set up Crashlytics or Sentry to catch errors. Set up analytics to see what features users are using. You can't fix what you don't see.

Manual deployment forever. If you're building and uploading manually each time, you will eventually ship the wrong version or forget a step. Automate it.

FAQ

Shipping an AI-built Flutter app isn't mysterious, it's just a checklist you've probably never seen before. Start with security and testing, optimize for real devices, and automate the rest. The apps that succeed aren't the ones that ship first; they're the ones that don't fall over on day two.
