zero_network_kit 1.0.2

Network diagnostics toolkit for Flutter: connectivity, ping, DNS, speed test, port scan and quality scoring across Android, iOS, macOS, Windows, Linux and Web.

Changelog

1.0.2

Added / 新增

• Swift Package Manager support — iOS and macOS now ship a Package.swift next to the CocoaPods podspec, so the plugin keeps working in projects that have migrated to SwiftPM. Native sources moved to <platform>/zero_network_kit/Sources/zero_network_kit/.
  • 支持 Swift Package Manager——iOS 与 macOS 在 CocoaPods podspec 之外新增 Package.swift，使插件在已迁移 SwiftPM 的工程中同样可用。原生源码移至 <platform>/zero_network_kit/Sources/zero_network_kit/。

Fixed / 修复

• Package description — the pub.dev description still advertised only five platforms after Web support shipped; it now lists all six.
  • 包描述——Web 支持上线后，pub.dev 上的描述仍只宣传五个平台，现已列出全部六个。
• podspec metadata — replaced the leftover macOS template values (placeholder summary, example.com homepage, Your Company author) and the iOS author with the real project metadata, and enabled the privacy manifest resource bundle on both platforms.
  • podspec 元信息——把 macOS 残留的模板值（占位 summary、example.com 主页、 Your Company 作者）与 iOS 的作者替换为真实项目信息，并在两个平台启用隐私清单资源包。

1.0.1

Added / 新增

• Web platform (partial) — the package now compiles and runs on Flutter Web. Connectivity is backed by connectivity_plus, ping falls back to an HTTPS round trip, DNS resolution uses DNS-over-HTTPS, and the speed test, quality score and benchmarks work unchanged. Capabilities the browser sandbox forbids degrade gracefully: native details (SSID / gateway / MAC / VPN) report null and TCP port checks return an "unavailable" result instead of throwing. Call NetworkCapabilities.current() to discover the supported set at runtime.
  • Web 平台（部分支持）——包现已可在 Flutter Web 上编译运行。连通性由 connectivity_plus 提供，Ping 退化为 HTTPS 往返耗时，DNS 解析改用 DNS-over-HTTPS，测速、质量评分与基准测试行为不变。浏览器沙箱禁止的能力会优雅降级： 原生详情（SSID / 网关 / MAC / VPN）返回 null，TCP 端口检测返回"不可用"结果而非抛异常。 运行时可调用 NetworkCapabilities.current() 查询当前支持的能力集合。

Fixed / 修复

• Speed test on the web — download and upload requests no longer send a Cache-Control header. It is not a CORS-safelisted header, so it forced an OPTIONS preflight that speed-test endpoints reject, surfacing as Failed to fetch.
  • Web 端测速——下载与上传请求不再携带 Cache-Control 头。该头不属于 CORS 安全头，会触发 OPTIONS 预检，而测速端点会拒绝该预检，最终表现为 Failed to fetch。

Changed / 变更

• Windows VPN detection — adapters are now also recognised from the driver name in their description (TAP-Windows, Wintun, WireGuard, OpenVPN, …) in addition to IF_TYPE_TUNNEL. IF_TYPE_PPP is deliberately not treated as a VPN because PPPoE broadband reports the same interface type.
  • Windows VPN 检测——除 IF_TYPE_TUNNEL 外，还会依据网卡描述中的驱动名识别 VPN 网卡（TAP-Windows、Wintun、WireGuard、OpenVPN 等）。有意不把 IF_TYPE_PPP 视为 VPN，因为 PPPoE 宽带拨号上报的也是该接口类型。

1.0.0

Added / 新增

• Connectivity — NetworkDiagnostic.checkConnection() returns a NetworkConnectionInfo snapshot with transport type, IPv4/IPv6, gateway, Wi-Fi SSID, signal strength (dBm), MAC address and VPN detection. NetworkDiagnostic.onConnectivityChanged streams a fresh snapshot on every change.
  • 连通性——NetworkDiagnostic.checkConnection() 返回 NetworkConnectionInfo 快照，包含传输类型、IPv4/IPv6、网关、Wi-Fi SSID、信号强度（dBm）、MAC 地址与 VPN 检测；NetworkDiagnostic.onConnectivityChanged 会在每次变化时推送新快照。
• Ping — NetworkDiagnostic.ping() measures latency with TCP handshake round trips on every platform, and can use the system ICMP ping command on desktop (PingMode.icmp). PingResult reports sent/received, packet loss, min/avg/max and jitter.
  • Ping——NetworkDiagnostic.ping() 在各平台以 TCP 握手往返测量延迟，桌面端还 可使用系统 ICMP ping 命令（PingMode.icmp）。PingResult 提供发送/接收数、 丢包率、最小/平均/最大耗时与抖动。
• DNS — NetworkDiagnostic.resolve() queries system plus any explicit resolvers over raw UDP, using the built-in DNS wire-format codec (DnsPacket), with concurrent or serialised execution and per-server DnsTestResult.
  • DNS——NetworkDiagnostic.resolve() 通过原始 UDP 查询 system 及任意指定 DNS 服务器，使用内置 DNS 报文编解码器（DnsPacket），支持并发或串行执行， 并为每台服务器返回 DnsTestResult。
• Speed test — NetworkDiagnostic.runSpeedTest() measures download and upload throughput plus latency/jitter/packet loss, with progress callbacks via SpeedTestProgress.
  • 测速——NetworkDiagnostic.runSpeedTest() 测量下载与上传速率，并附带延迟、 抖动与丢包率，通过 SpeedTestProgress 回调进度。
• Port check — NetworkDiagnostic.checkPort() returns a PortCheckResult (use isPortOpen() for a plain boolean) and scanPorts() performs bounded-concurrency TCP reachability checks.
  • 端口检测——NetworkDiagnostic.checkPort() 返回 PortCheckResult（仅需布尔值 时可用 isPortOpen()）；scanPorts() 以受限并发执行 TCP 可达性检测。
• Quality score — NetworkDiagnostic.evaluateQuality() and NetworkQualityEvaluator produce a 0–100 weighted score with a NetworkQualityLevel and actionable suggestions.
  • 质量评分——NetworkDiagnostic.evaluateQuality() 与 NetworkQualityEvaluator 产出 0–100 的加权评分，附带 NetworkQualityLevel 与可执行的优化建议。
• Full report — NetworkDiagnostic.diagnose() aggregates every probe into a NetworkDiagnosticReport.
  • 汇总报告——NetworkDiagnostic.diagnose() 将全部探测结果汇总为 NetworkDiagnosticReport。
• Benchmarks — NetworkBenchmark.runAll() and friends measure the diagnostics API itself and return BenchmarkSuiteResult.
  • 基准测试——NetworkBenchmark.runAll() 等方法测量诊断 API 自身的性能， 返回 BenchmarkSuiteResult。
• Configuration — NetworkDiagnosticConfig centralises hosts, timeouts, payload sizes and quality targets; ZeroNetworkKit.init() applies it globally and dispose() releases the owned HTTP client.
  • 配置——NetworkDiagnosticConfig 集中管理主机、超时、负载大小与质量目标； ZeroNetworkKit.init() 全局生效，dispose() 释放其持有的 HTTP 客户端。
• Native channel — getPlatformVersion() and getNetworkDetails() implemented for Android (Kotlin) and iOS (Swift).
  • 原生通道——getPlatformVersion() 与 getNetworkDetails() 已在 Android （Kotlin）与 iOS（Swift）实现。
• Desktop platforms — Windows, macOS and Linux are now supported (pubspec.yaml declares them); getPlatformVersion() and getNetworkDetails() are implemented for each. On desktop, SSID / signal strength are null; Windows additionally exposes gateway / MAC / VPN via the native layer.
  • 桌面平台——已支持 Windows、macOS 与 Linux（pubspec.yaml 已声明），并为各自 实现 getPlatformVersion() 与 getNetworkDetails()。桌面端 SSID 与信号强度为 null；Windows 还通过原生层额外提供网关 / MAC / VPN。
• Capabilities — NetworkDiagnostic.capabilities returns NetworkCapabilities, so callers can query-then-call and hide unsupported cards (e.g. SSID on desktop).
  • 能力集——NetworkDiagnostic.capabilities 返回 NetworkCapabilities， 调用方可"先查询再调用"，隐藏不支持的卡片（例如桌面端的 SSID）。
• Advanced API — services, ConnectivityAdapter, QualityEvaluator and the DnsPacket codec moved into package:zero_network_kit/advanced.dart; the root barrel stays small (models + facades + config).
  • 进阶 API——各项 service、ConnectivityAdapter、QualityEvaluator 与 DnsPacket 编解码器已移入 package:zero_network_kit/advanced.dart；根 barrel 保持精简（仅模型 + 门面 + 配置）。
