flutter pub add sync_http基于插件公开信息、社区数据与项目使用情况整理的选型参考。
sync_http 是 Dart 的同步 HTTP 客户端，旨在简化在异步操作不理想环境中的 HTTP 请求。它提供了一个简单的 API，用于同步执行 GET、POST、PUT 等 HTTP 方法，阻塞执行直到收到响应。这使其适用于需要简单线性控制流的场景，例如命令行工具或脚本。该包由 Google 维护，支持 Android、iOS、macOS、Windows 和 Linux 多个平台。

A Dart HTTP client implemented using RawSynchronousSockets to allow for synchronous HTTP requests.
Note: this package is only intended for very specialized use cases. For general HTTP usage, please see instead package:http.
This library should probably only be used to connect to HTTP servers that are hosted on 'localhost'. The operations in this library will block the calling thread to wait for a response from the HTTP server. The thread can process no other events while waiting for the server to respond. As such, this synchronous HTTP client library is not suitable for applications that require high performance. Instead, such applications should use libraries built on asynchronous I/O, including dart:io and package:http, for the best performance.
