Generate Release Version

Android Release Configuration

Before generating a release version of your Android app, you need to ensure the correct signing configuration is set up in your build.gradle file.

Update Signing Configuration

1. Open android/app/build.gradle
2. Locate the signingConfigs block
3. Make sure the release configuration is set to release instead of debug

android {
    signingConfigs {
        release {
            storeFile file("your-release-key.keystore")
            storePassword "your-store-password"
            keyAlias "your-key-alias"
            keyPassword "your-key-password"
        }
    }
    buildTypes {
        release {
            signingConfig signingConfigs.release
            minifyEnabled false
            shrinkResources false  
        }
    }
}

Important Notes

• Never commit your keystore file or passwords to version control
• Store your keystore file securely
• Keep a backup of your keystore file - if you lose it, you won't be able to update your app on the Play Store
• The keystore file should be placed in the android/app directory

Generating Release APK

1. Open terminal in your project root directory
2. Run the following command:

   flutter build apk --release
3. The release APK will be generated at:

   build/app/outputs/flutter-apk/app-release.apk

iOS Release Configuration

For iOS release builds:

1. Open Xcode
2. Select your target
3. Go to Signing & Capabilities
4. Ensure you have:
   • Valid provisioning profile
   • Valid distribution certificate
   • Correct team selected
   • Correct bundle identifier

Generating iOS Release

1. Open terminal in your project root directory
2. Run the following command:

   flutter build ios --release
3. Open the generated Xcode project:

   open ios/Runner.xcworkspace
4. In Xcode:
   • Select "Any iOS Device" as the build target
   • Go to Product > Archive
   • Follow the steps to upload to App Store Connect

Troubleshooting

Common issues and solutions:

• Android signing issues:

  • Verify keystore file exists in correct location
  • Check keystore passwords are correct
  • Ensure signingConfig is set to release

• iOS signing issues:

  • Verify certificates are valid in Apple Developer account
  • Check provisioning profiles are up to date
  • Ensure bundle identifier matches your app's configuration
