Enabling CFE warning/error reporting for NNBD shows warnings (mostly) in dart:mirrors, dart:html and friends.
The easiest way to enable the warning/error reporting while building the nnbd sdk is to change performNnbdChecks in pkg/front_end/lib/src/base/processed_options.dart to always return true, and run the compile_platform script directly:
tools/sdks/dart-sdk/bin/dart --packages=.packages --dfe=tools/sdks/dart-sdk/bin/snapshots/kernel-service.dart.snapshot pkg/front_end/tool/_fasta/compile_platform.dart --target=dartdevc dart:core --enable-experiment=non-nullable --single-root-scheme=org-dartlang-sdk --single-root-base=. org-dartlang-sdk:///sdk_nnbd/lib/libraries.json out/ReleaseX64NNBD/vm_outline_strong.dill out/ReleaseX64NNBD/ddc_platform.dill out/ReleaseX64NNBD/ddc_sdk.dill

@srujzs After you have cleaned up the analysis errors in dart:html we should use this feature to check that there are not any CFE failures left over.

Got it, I'll have the bot update this bug once dart:html is landed.

HTML errors are gone (on analyzer side), but still some others:

I'm going to unblock this since it's not blocked by 37931 completely. It's only blocked by the analyzer errors, which have been resolved.

html is clean now. I tried turning this as part of: https://dart-review.googlesource.com/c/sdk/+/134562
I'm hitting the following incorrect errors / traces:

If I hack around that, I also see:

_EDIT: I accidentally sent the comment before I was done writing._
@johnniwinther @stefantsov I tried running the compile_platform script as you described above and we are getting a lot of warnings of the from the SDK and patch files but then it fails with an error:
Error: SDK summary not found: out/ReleaseX64NNBD/vm_outline_strong.dill.
I'm not sure about the status of the VM and what we should expect to be available yet has this changed?
Many of the warnings we see are of the following form and might be some low hanging fruit for cleanup:
test_05.dart:14:41: Warning: Non-nullable variable 'name' is used before it's assigned.
const Foo(String name) : this._name = name;
^^^^
I played around a little and the warning goes away if you remove the const from the constructor.

Most warnings are fixed by https://dart-review.googlesource.com/c/sdk/+/135307

Any update on this issue?

AFAIK we can safely close this issue because all CFE errors have been enabled and we can build without any errors. @johnniwinther can you confirm?
nshahan

The DDC sdk is built without errors so I'll close this issue.
