android - Flutter 构建 Appbundle 错误 :* What went wrong: A problem occurred evaluating project ':app'

Question

这是我尝试在终端中运行“flutter build appbundle”时遇到的错误。
我已经在寻找一些解决方案，但没有一个与我得到的错误相同
FAILURE:构建失败并出现异常。

在哪里:
构建文件 'C:\Users\User_Name\Desktop\deploy\bahetra\android\app\build.gradle' 行:31

什么地方出了错:
评估项目 ':app' 时出现问题。

Malformed \uxxxx encoding.

这是我的“android\app\build.gradle”中的代码:

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: '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
   }

        versionCode flutterVersionCode.toInteger()

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

   }
   buildTypes {

问题在 key.properties 文件中。用正斜杠替换存储位置中的所有反斜杠，它应该可以工作。例如:
在 key.properties 文件中更新它:

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

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