Chain.forTrace constructor Null safety
- StackTrace trace
Returns the stack chain associated with trace
.
The first stack trace in the returned chain will always be trace
(converted to a Trace if necessary). If there is no chain associated
with trace
or if this is called outside of a capture zone, this just
returns a single-trace chain containing trace
.
If trace
is already a Chain, it will be returned as-is.
Implementation
factory Chain.forTrace(StackTrace trace) {
if (trace is Chain) return trace;
if (_currentSpec != null) return _currentSpec!.chainFor(trace);
if (trace is Trace) return Chain([trace]);
return LazyChain(() => Chain.parse(trace.toString()));
}
