android/app/build.gradle 中出现问题。因此未将其指定给 applicationId

Question

在此输入图片描述

这是什么问题？我不明白为什么会发生这种情况。虽然我已经成功地维护了所有

build.gradle

和

app/build.gradle

文件的组织。

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 newGradleException("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'
}

                // 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
            }
        }
    }

• 出了什么问题： 评估根项目“android”时出现问题。

配置项目“:app”时出现问题。 com.android.build.gradle.internal.dsl.AgpDslLockedException：设置applicationId为时已晚 已经阅读了它来配置该项目。 考虑将此调用移至评估期间， 或使用变体 API。

• 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。 使用 --scan 运行以获得完整的见解。 有什么问题

看起来它不喜欢你这样做：

    configurations.all {
        ...
        defaultConfig {
            // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
            applicationId "com.example.moto_park"
            // You can update the following values to match your application needs.
            // For more information, see: https://docs.flutter.dev/deployment/android#reviewing-the-gradle-build-configuration.
            minSdkVersion 21
            targetSdkVersion 33
            versionCode flutterVersionCode.toInteger()
            versionName flutterVersionName
            multiDexEnabled true
        }
      ...
    }

我认为没有太多理由以这种方式指定该块。 这些值都是静态的，所以为什么不将它们移动到 gradle 文件的顶部，如下所示：

android {
    applicationId "com.example.moto_park"
    minSdkVersion 21
    targetSdkVersion 33
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
    multiDexEnabled true
    ...
}
