Android & Flutter App Live JKS Create

 1) build.gradle JAVA (App)

def keystoreProperties = new Properties()

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

if (keystorePropertiesFile.exists()) {

   keystoreProperties.load(new FileInputStream(keystorePropertiesFile))

}

=> Android

   signingConfigs {

       create("release") {

            keyAlias = keystoreProperties["keyAlias"] as String

            keyPassword = keystoreProperties["keyPassword"] as String

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

            storePassword = keystoreProperties["storePassword"] as String

       }

   }

    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.getByName("release")

        }

    }

=> dependencies

dependencies {

    implementation 'androidx.core:core-ktx:1.12.0'

    implementation 'androidx.core:core:1.12.0'

}

build.gradle Kotlin (App)

import java.util.Properties

import java.io.FileInputStream

val keystoreProperties = Properties()
val keystorePropertiesFile = rootProject.file("key.properties")
if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(FileInputStream(keystorePropertiesFile))
}

    signingConfigs {

        create("release") {

            keyAlias = keystoreProperties["keyAlias"] as String?

            keyPassword = keystoreProperties["keyPassword"] as String?

            storeFile = keystoreProperties["storeFile"]?.let { file(it as String) }

            storePassword = keystoreProperties["storePassword"] as String?

        }

    }

    buildTypes {

        getByName("release") {

            signingConfig = signingConfigs.getByName("release")

             isMinifyEnabled = true

            isShrinkResources = true

            proguardFiles(

                getDefaultProguardFile("proguard-android-optimize.txt"),

                "proguard-rules.pro"

            )

        }

    }

2) key.properties

=> android folder create

keyAlias = cctv

keyPassword = 123456

storeFile = cctv.jks

storePassword = 123456

3) Create JKS Using Terminal (CMD)

keytool -genkey -v -keystore {JKS Save Path} -keyalg RSA -keysize 2048 -validity 10000 -alias {alias Name}
