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);
}

This can convert the following JavaScript trace:

1.1.4

  • Support source maps that depend on the uri of the location to resolve spans correctly.

1.1.3

  • Add a missing dependency on path.

1.1.2

  • Fix a typo in the previous fix.

1.1.1

  • Don't crash if the SyncPackageResolver has no package information at all.

1.1.0

  • mapStackTrace() now uses a SyncPackageResolver object from the package_resolver package to recreate package: URIs.

  • Deprecation: the packageRoot parameter to mapStackTrace is deprecated in favor of the packageInfo parameter described above. It will be removed in a future release.

1.0.5

  • Add compatibility for member names that include named arguments.

1.0.4

  • Add compatibility for Dart 1.10-style name munging.

1.0.3

  • Prefer "dart:" URLs to "package:" URLs.

1.0.2

  • Fix an off-by-one bug that was causing line numbers to be slightly off.

1.0.1

  • Don't crash when mapping stack chains.

1.0.0

  • Initial release.
