firebase - 评估项目 ':app' 时出现问题。构建gradle问题

Question

我试图运行我的第一个 firebase 应用程序，但由于这个错误它没有工作：

FAILURE：构建失败并出现异常。

• 其中：构建文件 'C:\Users\boras\OneDrive\Masaustu\Software\ProgramlamaTemelliYazilim\Flutter\firebase_application\firebase_application\android\app\build.gradle' 行：29
• 出了什么问题：评估项目“：app”时出现问题。

方法没有签名：build_884xt67ny8crpgv70jgbem96p.android() 适用于参数类型：(build_884xt67ny8crpgv70jgbem96p$_run_closure2) 值：[build_884xt67ny8crpgv70jgbem96p$ure2) 值：[build_884xt67ny8crpgv70jgbem98e9c$_run_closure2@1

• 尝试：使用 --stacktrace 选项运行以获取堆栈跟踪。使用 --info 或 --debug 选项运行以获得更多日志输出。运行 --scan 以获得完整的见解。

这就是我 android/app/build.gradle 的样子：

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'
}

    }

    buildTypes {

            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }
}
