Flutter build Appbundle Error:* What went wrong: A problem occurred evaluating project ':app'

This is the error that I'm getting when I'm trying to run "flutter build appbundle" in terminal. I already search for some solution but none of it has the same error as I get

FAILURE: Build failed with an exception.

Malformed \uxxxx encoding.

This is the code from my "android\app\build.gradle":

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

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

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

    def keystoreProperties = new Properties()
   def keystorePropertiesFile = rootProject.file('key.properties')
   if (keystorePropertiesFile.exists()) {
       keystoreProperties.load(new FileInputStream(keystorePropertiesFile)) // line 31
   }

android {
    compileSdkVersion 30

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.bahetra"
        minSdkVersion 16
        targetSdkVersion 30
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }

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

flutter {
    source '../..'
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
}

keytool -genkey -keyalg RSA -alias selfsigned -keystore upload-keystore.jks -storepass %password% -validity 360 -keysize 2048

%password% is your password

The problem is in the key.properties file. The store location contains backslashes, which need to be replaced with forward slashes. This will fix the issue. For example,

Update this in key.properties file:

storeFile= C:\Users\<user name>\upload-keystore.jks

to this:

storeFile=C://Users//<user name>//upload-keystore.jks

just replace the backslash to forward-slash in key.properties in storeFile

before

storeFile=<location>\upload-keystore.jks

after

storeFile=<location>/upload-keystore.jks

The issue is in key.properties file. Replace all the backslash in the store location with the forward slash and it should work. Eg:

Update this in key.properties file:

storeFile= C:\Users\<user name>\upload-keystore.jks

to this:

storeFile=C:/Users/<user name>/upload-keystore.jks
