Firebase 在项目上找不到参数[]的方法属性（）：org.gradle.api.project类型的应用程序

我在Android Studio中更新了Flitter之后出现了这个错误， 请帮忙， 我厌倦了升级和降级Firebase身份验证依赖项 颤振医生命令显示无错误， 我也尝试过改变类路径，但没有成功 但当我建造时，我总是 获取此错误

这是我的应用程序/build.gradle

def localPropertiesFile = rootProject.file('local.properties')

    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

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

    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')

这是我的设置

include ':app'

def flutterProjectRoot = rootProject.projectDir.parentFile.toPath()

def plugins =  new Properties()
def pluginsFile =  new File(flutterProjectRoot.toFile(), '.flutter-plugins')
if (pluginsFile.exists()) {
    pluginsFile.withReader('UTF-8') { reader -> plugins.load(reader) }
}

plugins.each { name, path ->
    def pluginDirectory = flutterProjectRoot.resolve(path).resolve('android').toFile()
    include ":$name"
    project(":$name").projectDir = pluginDirectory
}

更改此项：

def localProperties =  Properties()

为此：

def localProperties =  new Properties()

更改此项：

def localProperties =  Properties()

为此：

def localProperties =  new Properties()

您需要从更新build.gradle

def localProperties=Properties

到

def localProperties=新属性

将解决您的问题。
