Steps to Reproduce

Look at any issue reported from a Flutter/Dart app. Navigate to stack trace and turn on the "Raw stack trace" option.

The presented Dart stack trace look something like this:

  File "my_api.g.dart", line 975, in MyPeripheralManagerHostApi.startAdvertising
  File "<asynchronous suspension>"
  File "my_peripheral_manager.dart", line 138, in MyPeripheralManager.startAdvertising
  File "<asynchronous suspension>"
  File "sync_ble_controller.dart", line 148, in SyncBleController._initBlePeripheral

Expected Result

The raw/native stack trace format for Dart for the above trace should look something like this. Also note the package reference and the source path missing from the current Sentry's "raw stack trace" presentation, which is required in order to uniquely identify source of the issue.

#1  MyPeripheralManagerHostApi.startAdvertising (package:bluetooth_low_energy_darwin/lib/src/my_api.g.dart:975)
#2  <asynchronous suspension>
#3  MyPeripheralManager.startAdvertising (package:bluetooth_low_energy_darwin/lib/src/my_peripheral_manager.dart:138)
#4  <asynchronous suspension>
#5  SyncBleController._initBlePeripheral (package:xyz/lib/controllers/sync_ble_controller.dart:148)

Actual Result

The Dart stack trace presentation in the Sentry's web UI is not anywhere alike Dart's native/raw stack trace (e.g. if you catch and print stack trace in the Dart code).

Also if you copy it from the Sentry web UI, the stack trace format is not recognized by the Dart tools, e.g. "Code / Analyze Stack Trace or Thread Dump..." action in the IntelliJ Dart/Flutter plugins and as a result you can't easily navigate to the source code from the stack trace analysis view in the IDE.

Are you willing to submit a PR?

hey thanks for raising this issue.

This is indeed not the behaviour we want, currently we fallback to a python representation for dart stacktraces (didn't know this either) 😅

We'll take a look at that

For native stacktrace it already works correctly

sentry-dart/dart/lib/src/sentry_stack_trace_factory.dart

Lines 111 to 113 in 0f067d3

	return SentryStackFrame(
	instructionAddr: '0x${match.group(1)!}',
	platform: 'native', // to trigger symbolication & native LoadImageList

For Dart stacktraces (in addition to the problem on the website) you need to set the platform for the frame to dart, which currently is not done

sentry-dart/dart/lib/src/sentry_stack_trace_factory.dart

Lines 126 to 133 in 0f067d3

	var sentryStackFrame = SentryStackFrame(
	absPath: abs,
	function: member,
	// https://docs.sentry.io/development/sdk-dev/features/#in-app-frames
	inApp: _isInApp(frame),
	fileName: fileName,
	package: frame.package,
	);

On the web platform, you may need to set platform to JS or something.

Any update or what is holding this up?
This is a critical essential issue for Dart/Flutter and there seem to be understanding what need to be fixed.
