Zichang Guo d7483c330c [dart:io] Concurrently resolve IPv4 and IPv6 addresses on iOS.
Original issue: On iOS, The problem is that people on iOS can have their
IPv6 misconfigured so it doesn't work, but it's still turned on.
Additionally getaddrinfo on that platform doesn't handle that case well,
meaning that the IPv6 lookup takes a long time to time out, delaying the
legitimate response.

This fix will issue a concurrent lookup for IPv4 and IPv6 on iOS.
Whichever IP comes first will be used to try to build the connection.

Dart

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
