Flutter socket.io和Node.js套接字服务器

Question

你好，大家好吗？你能帮我吗？我使用flutter_socket_io创建了聊天应用程序。它在android 5,6,7上运行良好，但在android 8、9、10上却无法运行。我正在使用nodejs套接字服务器。

build.gradle
compileSdkVersion 28

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

lintOptions {
    disable 'InvalidPackage'
}

defaultConfig {
    // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
    applicationId "com.example.socketapp"
    minSdkVersion 16
    targetSdkVersion 29
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
