Description:

source map stack trace

source_map_stack_trace is a package for converting stack traces generated by
dart2js-compiled JavaScript code into readable native Dart stack traces using
source maps. For example:
import 'package:source_map_stack_trace/source_map_stack_trace.dart';

void main() {
var jsTrace = // Get a StackTrace generated by dart2js.
var mapping = // Get a source map mapping the JS to the Dart source.

// Convert jsTrace to refer to the Dart source instead.
var dartTrace = mapStackTrace(jsTrace, sourceMap);
print(dartTrace);
}
