Flutter – FAILURE: Build failed with an exception. for release build

I failed to build flutter app.

I wrote in tarminal of VSCode.

`flutter build appbundle –release““

but failed.

FAILURE: Build failed with an exception.

* Where:
Build file 'C:UsersNAMEsourcereposNAMEworkflutterAPP_NAMEandroidappbuild.gradle' line: 58

* What went wrong:
A problem occurred evaluating project ':app'.
> Could not get unknown property 'keystoreProperties' for SigningConfig$AgpDecorated_Decorated{name=release, storeFile=null, storePassword=null, keyAlias=null, keyPassword=null, storeType=pkcs12, v1SigningEnabled=true, v2SigningEnabled=true, enableV1Signing=null, enableV2Signing=null, enableV3Signing=null, enableV4Signing=null} of type com.android.build.gradle.internal.dsl.SigningConfig$AgpDecorated.

* Try:

build.gradle’ line: 58 is a line starts from keyAlias…

    signingConfigs {
        release {
            keyAlias keystoreProperties['keyAlias']
            keyPassword keystoreProperties['keyPassword']
            storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
            storePassword keystoreProperties['storePassword']
        }
    }

I added these code at androidappbuild.gradle

enter image description here

and I made androidappkey.jks

and I modified androidkey.properties

storePassword=MYPASSWORD
keyPassword=MYPASSWORD
keyAlias=key
storeFile=key.jks

    The problem was solved.

    
def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

////////////////////////////
// inserted here

def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}

////////////////////////////

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

    You need to add code like this to initialize the keystoreProperties, for example below the other "def" statements at the top of the file:

    def keystoreProperties = new Properties()
def keystorePropertiesFile = file('/path/to/your/key.properties')
if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}
