Static Methods

applyPayloadLimit(String? payload) → String?
Returns payload unchanged when its length is ≤ 1024 characters, or null when it exceeds the limit. Bodies over the limit are dropped entirely rather than truncated to avoid sending partial/misleading data.
buildCaptureContext({required String url, required List<CxNetworkCaptureRule> rules, required Map<String, String> reqHeaders, Map<String, String>? resHeaders, String? requestPayload, String? responsePayload}) → Map<String, dynamic>
Resolves the first matching CxNetworkCaptureRule for url and returns a map of the capture-sensitive fields (request/response headers and payloads) that should be included in a network telemetry span.
buildCustomSpanNetworkContext() → Map<String, String>
Returns hybrid-network linkage fields for native SDK consumption.
filterHeaders(Map<String, String> headers, List<String> allowlist) → Map<String, String>
Filters headers to only those whose name (case-insensitive) appears in allowlist. Output keys use the casing from allowlist (mirrors Android SDK behaviour).
generateHex(int length) → String
Generates a hex string of length characters using a cryptographically secure RNG.
resolveNetworkCaptureRule(String url, List<CxNetworkCaptureRule> rules) → CxNetworkCaptureRule?
Returns the first CxNetworkCaptureRule whose url exactly matches or whose urlPattern regex matches url. Returns null if no rule matches.
resolveTraceId() → String
Returns the traceId to use for an outgoing network request.
shouldAddTraceParent(String? requestURLString, CXExporterOptions options) → bool
Header-side rule only. Callers skip network instrumentation entirely when it is switched off. Sampling deliberately plays no part: a sampled-out session keeps propagating so backend traces still correlate.
