Flutter final release codes

 Here are the steps to generate aab file

1. Create your Keystore

 Keystore is the file you should have to sign your AAB file.

 Run the following command in Terminal at your project's root directory.

 keytool -genkey -v -keystore ttwenty.jks -keyalg RSA -keysize 2048 -validity 10000 -alias ttwenty

 After entering this command, you will be asked to fill key's password and some information.

2. Create a reference file to Keystore

 Create a file named key.properties at [project root]/android/

 storePassword=password from previous step

 keyPassword=password from previous step

 keyAlias=ttwenty

 storeFile=../../ttwenty.jks

 if you create with different key alias, please specify it in keyAlias.

 For storeFile if you choose to put Keystore file at the root of your Flutter's project directory. This file's path would work.

3. Modify app/build.gradle

 Load keystore's properties

  Open [project]/android/app/build.gradle, look for android block, and put following code at the top of its.

     def keystoreProperties = new Properties()

      def keystorePropertiesFile = rootProject.file('key.properties')

      if (keystorePropertiesFile.exists()) {

          keystoreProperties.load(new FileInputStream(keystorePropertiesFile))

      }

      android {

           ...

      }

    Replace buildTypes block

    find buildTypes block. it should look like the below:

     buildTypes {

         release {

             // TODO: Add your own signing config for the release build.

            // Signing with the debug keys for now,

             // so `flutter run --release` works.

           signingConfig signingConfigs.debug

         }

     }

     you have to replace it with following code:

     signingConfigs {

       release {

            keyAlias keystoreProperties['keyAlias']

            keyPassword keystoreProperties['keyPassword']

            storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null

           storePassword keystoreProperties['storePassword']

          }

     }

     buildTypes {

         release {

             signingConfig signingConfigs.release

         }

     }

4. Let's sign and build the release version

 flutter clean

 flutter pub get

 flutter build appbundle
