[Dart2Wasm] Error root cause is obscured by stacktrace #55033

Open itsjustkevin opened 6 months ago

itsjustkevin commented 6 months ago

Dart2Wasm errors are not easily visible.

Background

When attempting a Flutter Wasm build while utilizing a plugin or package that is not yet migrated, the error logged before logging the offending error in the package/plugin, followed by the stack trace.

This makes it difficult to immediately understand what the issue is.

Expectation

I would expect that the error is logged at the end.

(what's this?)

mkustermann commented 6 months ago

This looks more like a CFE issue.

Also for most compilers one wants to look at the very first error, which is pretty clear

┌─ Experimental feature ───────────────────────────────┐

Context: The unavailable library 'dart:html' is imported through these packages:

Because following errors are usually consequences of the first.

johnniwinther commented 5 months ago

As far as I can see the first error is the root cause (dart:html not being available).

@itsjustkevin What (other?) result would you have preferred in this case?

itsjustkevin commented 5 months ago

@johnniwinther this may be a special case, due to the fact that dart:html is not WASM compatible, that I am looking at from a user perspective.

As a user attempting a Wasm build of my Flutter app, I might have thousands of lines of errors returned, making it difficult for me to hunt for the issues.

For the users, it may be helpful to append the offending libraries to the output:

The following libraries are unavailable:
dart:html
dart:convert
dart:math
