✨ New Features #

• Added BaseUdpSrvClient abstract class for shared SRV lookup logic.
• Implemented:
  • SystemUdpSrvClient: queries SRV records via system-configured DNS (UDP → TCP fallback).
  • PublicUdpSrvClient: queries SRV records via public resolvers (Quad9, AdGuard, Yandex, OpenDNS, etc.).
  • DnsOverHttps.lookupSrvMulti(): sequential SRV lookup (Google → Cloudflare fallback).
  • DnsOverHttps.lookupSrvParallel(): parallel SRV lookup (runs both resolvers simultaneously).
• Added SrvRecord model for typed SRV response handling instead of generic Map.
• Improved example dns_client_example.dart to demonstrate all client types:
  • System resolver
  • Public resolver
  • DoH (Google, Cloudflare, Mullvad)
• Added complete test coverage for:
  • UDP/TCP SRV clients
  • DoH SRV (multi + parallel)
  • System and public resolver detection
  • Error fallback (UDP timeout → TCP)
• Refactored project structure:

lib/src/doh/ lib/src/udp_tcp/ lib/src/models/ example/dns_client_example.dart

⚙️ Improvements #

• Enhanced fallback logic between Google and Cloudflare DoH resolvers.
• Added English-only documentation comments for consistency.
• Improved debug logging for all SRV clients.

🧩 Fixes #

• Better error handling for IPv6 and system DNS detection.
• Tests now handle dynamic DNS environments safely (no hardcoded IPs).
• Fixed internal method visibility and export paths.

🧪 Tests #

• Added new unit tests for:
  • DnsOverHttps.lookupSrvMulti()
  • DnsOverHttps.lookupSrvParallel()
• Ensured 100% test coverage across DoH, UDP, and TCP clients.

🔧 Misc #

• Updated GitHub workflows (analyze.yml, test.yml).
• Cleaned up comments and improved readability throughout the codebase.

🛠 Fixes #

• Exported DnsOverHttpsBinaryClient in super_dns_client.dart so it is now publicly accessible from the package import.

🔧 Internal #

• Minor cleanup before pub.dev publish

✨ New Features #

• Added DnsOverHttpsBinaryClient for binary DNS-over-HTTPS lookups (RFC 8484).
• Support for SRV record resolution over DoH.
• Added DnsResolver object model (name, url, supportsGet, isTrusted).
• Built-in non-GAFAM resolvers:
  • Quad9
  • AdGuard
  • Yandex
  • OpenDNS
  • Mullvad (GET only)

⚙️ Improvements #

• Automatic GET/POST selection depending on resolver capability.
• Unified lookup() and lookupDataByRRType() API with optional resolverName.
• Enhanced error handling for invalid resolvers and DoH failures.

🧪 Tests & Examples #

• Added unit tests for SRV and A record lookups via Quad9.
• Updated example to demonstrate both DnsOverHttps and DnsOverHttpsBinaryClient usage.
