Debugger views include private getters which always fail if the current stack frame is from in the library that declares them #4296
Description
Describe the bug
I am using VSCode to debug my flutter app. This may have been doing it for a long time. I'm new to debugging. but I noticed as im steeping through the code every variable has a property called _identityHashCode and instead of a value if I hover over it it says this.
<error: org-dartlang-debug:synthetic_debug_expression:1:1: Error: The getter '_identityHashCode' isn't defined for the class 'MethodChannelFirebase'.
- 'MethodChannelFirebase' is from 'package:firebase_core_platform_interface/firebase_core_platform_interface.dart' ('/C:/Users/andre.viau/AppData/Local/Pub/Cache/hosted/pub.dev/firebase_core_platform_interface-4.5.2/lib/firebase_core_platform_interface.dart').
Try correcting the name to the name of an existing getter, or defining a getter or field named '_identityHashCode'.
_identityHashCode
^^^^^^^^^^^^^^^^^>
It says this for every variable it shows in the debug window. This isnt causing any crashes or anything that I am aware of yet.
To Reproduce
Steps to reproduce the behavior:
- Click on Run on the top bar and choose Start Debugging
- Go to the run and debug tab on the side of vscode and expand the "This": section to show the _identityHashCode property.
- Step through the code to show different variables.
Expected behavior
A clear and concise description of what you expected to happen.

This error should be harmless, but I agree we should remove it. The original legacy debug adapters did filter this out:
Dart-Code/src/debug/dart_debug_impl.ts
Lines 1428 to 1429 in cf21e01
However the new SDK debug adapters are missing this.

Private getters will be filtered from this list from a future update (via dart-lang/sdk@c53f705). The change is in the SDK so it'll show up in a future SDK update (rather than a Dart-Code update).
