Release - App Store & Play Store Preparation

Prepare Flutter apps for production release. Handles signing, icons, splash screens, and store setup.

When to Use This Skill

Setting up Android signing (keystore, key.properties)
Configuring iOS signing (certificates, provisioning profiles)
Creating app icons for iOS and Android
Setting up splash screens
Preparing for App Store Connect or Google Play Console
Verifying release readiness
Building release APK/AAB/IPA

Manual vs CI/CD Release

Approach	Use When	Signing
Manual (this skill)	First release, small team	Local keystore, Xcode
CI/CD (`/ci-cd`)	Regular releases, teams	GitHub Secrets, Fastlane

Recommendation: Start with manual release. Set up CI/CD when you need automation.

Quick Reference

Platform Requirements

Platform	Signing	Store	Build Command
Android	Keystore + key.properties	Play Console	`flutter build appbundle --release`
iOS	Xcode Team + Provisioning	App Store Connect	`flutter build ipa --release`

Commands

# Audit release readiness
dart run .claude/skills/release/scripts/check.dart

# Build release
flutter build appbundle --release  # Android
flutter build ipa --release        # iOS

check.dart Option	Purpose
`--platform android/ios`	Audit specific platform only
`--fix`	Auto-fix .gitignore patterns
`--checklist`	Generate markdown checklist
`--capabilities`	Detect required iOS capabilities
`--keytool-command`	Generate keystore creation command

Workflow

1. Audit Current State

dart run .claude/skills/release/scripts/check.dart

Identifies: Missing keystore, unsigned iOS, missing icons, uncommitted .env files.

2. Create Assets

See assets-guide.md:

App icon: 1024x1024 PNG (no transparency for iOS)
Splash screen: Configure flutter_native_splash

3. Configure Android Signing

See android-guide.md:

Generate keystore
Create key.properties (DO NOT COMMIT)
Update build.gradle.kts
Create proguard-rules.pro

4. Configure iOS Signing

See ios-guide.md:

Open Xcode
Select Team
Configure capabilities
Create App ID on Apple Developer

5. Store Setup

See platform guides:

android-guide.md - Play Console setup
ios-guide.md - App Store Connect setup

6. Build & Test Release

# Android
flutter build appbundle --release

# iOS
flutter build ipa --release

7. Final Verification

See checklist.md for comprehensive pre-release checklist.

File Structure

After release preparation:

android/key.properties          # Signing config (DO NOT COMMIT)
android/app/build.gradle.kts    # With signing config
android/app/proguard-rules.pro  # R8 rules
ios/Runner.xcworkspace          # With signing configured
assets/icons/app_icon.png       # 1024x1024 source icon
pubspec.yaml                    # flutter_native_splash config
.gitignore                      # Must include key.properties, *.jks

Security Checklist

Critical files that must NEVER be committed:

File	Contains	Gitignore Pattern
`key.properties`	Keystore passwords	`android/key.properties`
`.jks` / `.keystore`	Signing keys	`.jks` / `.keystore`
`.env`	API keys, secrets	`.env` / `.env.*`
`*.p8`	Apple private keys	`*.p8`
`google-services.json`	Firebase config (optional)	Varies

Checklist

Assets:

App icon 1024x1024 PNG (no transparency for iOS)

Provisioning profile configured
flutter build ipa --release succeeds

Store:

Common Issues

Issue	Solution
"Keystore was tampered with"	Verify password in key.properties
"No signing certificate"	Xcode > Preferences > Accounts > refresh
ProGuard errors	Add keep rules to proguard-rules.pro
Icons don't update	Run `flutter clean` then rebuild
