spanId property
A unique identifier for a span within a trace, assigned when the span is created. The ID is an 8-byte array. An ID with all zeroes OR of length other than 8 bytes is considered invalid (empty string in OTLP/JSON is zero-length and thus is also invalid).
This field is optional. If the sender specifies a valid span_id then it SHOULD also specify a valid trace_id.
The receivers SHOULD assume that the log record is not associated with a span if any of the following is true:
- the field is not present,
- the field contains an invalid value.

$core.List<$core.int> get spanId => $_getN(8);
