Build Release AAB (for Play Store)

1. Generate a keystore (one-time):

   keytool -genkey -v -keystore ~/upload-keystore.jks -keyalg RSA -keysize 2048 -validity 10000 -alias upload

2. Create android/key.properties:

   storePassword=YOUR_STORE_PASSWORD
   keyPassword=YOUR_KEY_PASSWORD
   keyAlias=upload
   storeFile=C:/Users/YOU/upload-keystore.jks

3. Update android/app/build.gradle — add signing config:

   def keystoreProperties = new Properties()
   def keystorePropertiesFile = rootProject.file('key.properties')
   if (keystorePropertiesFile.exists()) {
       keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
   }
   
   android {
       signingConfigs {
           release {
               keyAlias keystoreProperties['keyAlias']
               keyPassword keystoreProperties['keyPassword']
               storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
               storePassword keystoreProperties['storePassword']
           }
       }
       buildTypes {
           release {
               signingConfig signingConfigs.release
           }
       }
   }

4. Build:

   flutter build appbundle --release
