class Analyzer::Dart::Http

Overview

dart:io's HttpServer is Dart's built-in HTTP server surface. It has no declarative router, so routes are usually guards over HttpRequest.method and HttpRequest.uri.path inside an await for or listen handler.

Defined in:

analyzer/analyzers/dart/http.cr

Whole-file detection gate, evaluated once per .dart file. A precompiled Regex.union (PCRE2 JIT) replaces the two OR-ed String#includes? scans it used to run — provably equivalent since union auto-escapes each literal.

Instance-side view of the same declaration. The per-file rescues live on this base class, which has no way to name the analyzer that is running inside them, so a skipped file could not be attributed to a tech. Deriving it from analyzer_for keeps the name written exactly once.
