TrackedHttpOverrides class
HttpOverrides that instruments low-level dart:io HttpClient requests,
emitting a client span with W3C Trace Context Level 1 (traceparent
version 00) injected into headers.
Install globally with install (preferred) or
HttpOverrides.global = TrackedHttpOverrides();.
When previous is set, createHttpClient delegates to that override
(preserving certificate pinning, SecurityContext, etc.), installs the
instrumented connectionFactory for DNS/connect timing, then wraps the
result for span recording. This is the mechanism used when your app sets
HttpOverrides.global before VuTelemetry.initialize with
instrumentations.http: true.

Static Properties
- bodyOrphanTimeoutForTesting ↔ Duration
-
Test-only orphan timeout. Restore with resetBodyOrphanTimeoutForTesting.
getter/setter pair
Static Methods
-
install(
{HttpConnectionFactory? connectionFactory}) → TrackedHttpOverrides - Sets HttpOverrides.global to a new TrackedHttpOverrides, chaining any existing global / zone overrides so prior behaviour is preserved.
-
resetBodyOrphanTimeoutForTesting(
) → void
Constants
- bodyOrphanTimeout → const Duration
- Wait after response metadata is read before closing a span whose body was never listened to. Matches dart:io HttpClient.idleTimeout.
