Trace.parse constructor Null safety
- String trace
Parses a string representation of a stack trace.
trace
should be formatted in the same way as a Dart VM or browser stack
trace. If it's formatted as a stack chain, this will return the equivalent
of Chain.toTrace.
Implementation
factory Trace.parse(String trace) {
try {
if (trace.isEmpty) return Trace(<Frame>[]);
if (trace.contains(_v8Trace)) return Trace.parseV8(trace);
if (trace.contains('\tat ')) return Trace.parseJSCore(trace);
if (trace.contains(_firefoxSafariTrace) ||
trace.contains(_firefoxEvalTrace)) {
return Trace.parseFirefox(trace);
}
if (trace.contains(chainGap)) return Chain.parse(trace).toTrace();
if (trace.contains(_friendlyTrace)) {
return Trace.parseFriendly(trace);
}
// Default to parsing the stack trace as a VM trace. This is also hit on
// IE and Safari, where the stack trace is just an empty string (issue
// 11257).
return Trace.parseVM(trace);
} on FormatException catch (error) {
throw FormatException('${error.message}\nStack trace:\n$trace');
}
