web_compilers: Need a better error when there are unsupported platforms #2200

kevmoo · 2019-04-18T23:07:23Z

Just went through this

[WARNING] build_web_compilers:entrypoint on web/main.dart: Skipping compiling repo_manager|web/main.dart with ddc because some of its
transitive libraries have sdk dependencies that not supported on this platform:

repo_manager|lib/src/util.dart
pana|lib/src/utils.dart
github|lib/server.dart
github|lib/src/server/hooks.dart

https://github.com/dart-lang/build/blob/master/docs/faq.md#how-can-i-resolve-skipped-compiling-warnings

I'd love to see the link going from web/main.dart through to the library causing the problem.

The text was updated successfully, but these errors were encountered:

jakemac53 · 2019-04-19T15:52:30Z

Should we make a more general tool for this and just link it? I don't think we want gigantic error messages...

kevmoo · 2019-04-19T16:00:05Z

gigantic error message is better than incomplete error message. I had to do a lot of guess work to figure out what was causing the problem!

jakemac53 · 2019-04-19T16:03:12Z

There are other use cases for wanting to know why you depend on some dart library though - which is why I was thinking a more general tool might make sense?

jakemac53 · 2019-04-19T16:12:44Z

I think a reasonable path forward here would be to output a file when we hit this case that represents all the paths to these bad libraries, probably DOT file format so users can easily visualize that in whatever they would like?

jakemac53 · 2019-04-19T17:14:00Z

Actually nvm I think something simpler is probably fine, will just output the shortest path to each unsupported module. Note this will be module paths not import paths.

jakemac53 · 2019-04-19T17:36:29Z

Ok, so I tried doing that with just the module graph and it ends up just being confusing, see this output from repo_manager before it was fixed.

The dart files here are misleading - none of the listed paths actually exist in terms of the real dart imports. Obviously the formatting etc could be cleaned up but I think we would have to drop back to the actual dart import paths to provide useful feedback which would be a fair bit more expensive.

GreenAppers · 2019-08-10T21:03:48Z

How can we go about debugging this in the meantime? I'm getting same error combined with "Unable to read module information for package:flutter, make sure you have a dependency on it in your pubspec.". Of course there is no flutter in pub deps or elsewhere, only flutter_web. I can't figure out what the problem is. The only thing that works is downgrading build_web_compilers to 1.2.2. Then the error "Unable to read module information for package:flutter" still prints, but it seems that it is not treated as fatal. Resulting web app works without observed defects.

GreenAppers · 2019-08-10T23:14:52Z

Ah. Finally found it. An import dart:io.

rostopira · 2019-09-26T14:49:14Z

What except dart:io could cause this? I've searched, io package doesn't seem to be referenced in my code

rostopira · 2019-09-26T14:56:14Z

I've removed every import from and web endpoint, except flutter/material and still getting an error
I've a lot of libraries in pubspec.yaml, but they are used in different endpoint
Dev channel v1.10.6

jakemac53 · 2019-09-26T14:59:03Z

If you are importing from lib/src/ in your own package that can cause this (you can end up importing a module that contains more libraries in the same package that you didn't actually directly import).

Also flutter itself definitely has dart:io imports but we have a (hopefully temporary) whitelist for it. You might need to update flutter to get that?

rostopira · 2019-09-26T15:01:18Z

I have lib/web_main.dart (without any imports except material) and using flutter build web -t lib/web_main.dart --verbose command for build. I have no issues when using flutter run -d web however

I'm already on latest flutter even tried master channel

jakemac53 · 2019-09-26T15:06:49Z

I don't believe flutter build web uses this package. What error are you seeing?

Even tried this as entry point:

import 'package:flutter/material.dart';

main() => WidgetsApp(color: Color(0xFFFF0000));

Still error

jakemac53 · 2019-09-26T15:11:01Z

Interesting... cc @jonahwilliams maybe something changed here so it is using this package for release builds as well.

In that case we likely need to whitelist the flutter packages in the call to computeTransitiveDependencies for this builder.

rostopira · 2019-09-26T15:12:25Z

The most strange thing, that it were working fine yesterday, and still working fine in project which doesn't have dependencies in pubspec except flutter

jakemac53 · 2019-09-26T15:14:31Z

It is possible that this is compiling some additional entrypoints? There should be some additional log lines that tell you what app it was actually trying to compile (should be right above this).

Here is full log, but I don't see anything about other entry-points

Huh, I think maybe flutter tool is stripping out our logger info lines? @jonahwilliams

It looks like it did in fact compile the dummy_main.dart file which I assume is the simple one you made. It is failing when presumably trying to compile some other file.

rostopira · 2019-09-27T07:17:03Z

Well, IDK why I didn't tried it yesterday, but commenting out all other entrypoints (I have 3) fixed issue. So yeah, it's trying to build other entrypoints

rostopira · 2019-09-27T07:34:00Z

I've made simple project with two entrypoints to reproduce https://github.com/rostopira/bug_reproduce
Should I open new issue for this?

jonahwilliams · 2019-10-07T19:51:00Z

FWIW we've disabled the unsupported platform checks in the latest flutter

jakemac53 · 2023-09-01T18:00:11Z

note that you can use the import_path package to find the import path to libraries that aren't usable on the web
