[web_compilers] Skipping compiling with dart2js because some of its transitive libraries have sdk dependencies that are not supported on this platform:.

[MichealReed]

There should be a way to override the unsupported platform check. #2200 (comment) mentions flutter has this disabled, how?

The code paths in my library have no problems with web yet I cannot use webdev serve to compile a js library.

dart-lang/sdk#50181

Many parts of analyzer work on web yet it seems to be blacklisted. How can I force this to allow a package through and compile the code?

If I dart2js then webdev serve, even though webdev serve skips building, the file built through dart2js works. If I must use dart2js, how can I fully package all the dart dependencies? These packages work fine in flutter too, so I should be able to build them with webdev serve.

I'm not sure what's recommended here, it might make sense to ask first over at the webdev repo

https://github.com/dart-lang/webdev

but indeed web_compilers is in this repo, happy to help if any fix is turns out to be needed.
