Yusufihsangorgel/README.md

Software engineer working across Flutter, Dart, and Go, where client apps, native code, and infrastructure have to stay correct under load.

Upstream

Reworking package:dart_mcp's transport for the 2026 MCP specification: the lifecycle split, request-scoped dispatch, and decoded-message channels are merged. A change landed in the Dart SDK: the analyzer now rejects Struct-constrained mixin applications. Also merged fixes into shelf, Drift, FlutterFire, Retrofit, and Bun; more across dart-lang, flutter, and grpc-go on my profile.

Packages

20+ on pub.dev. Several bind native C and C++ libraries through Dart's build hooks, so there is nothing to install:

  • re2: linear-time regex, immune to catastrophic backtracking
  • simdjson_dart: SIMD JSON parsing over simdjson
  • blake3_ffi: BLAKE3 hashing at native throughput

Others are pure Dart:

  • resilience: retries, circuit breaker, rate limiter, bulkhead
  • redis_task_queue: a server-side queue with retries and dead letters
  • mcp_probe: a conformance harness for MCP servers

The full list is on pub.dev.

Writing

Debugging a 45-second deadlock in MCP's Streamable HTTP.
