Flutter entry scripts in lib/web are incorrectly considered Dart-web

I get this error after the Dart-code (or Flutter-code) plugin wanted to update the webdev package:

Unhandled exception:
ProcessException: ***OUT***

***ERR***
The Flutter SDK is not available.

I'm using Visual Studio Code 1.47.3 with Dart/Flutter code 3.13.0 on macOS 10.15.6

I'm using:

$ flutter --version
Flutter 1.21.0-6.0.pre.141 • channel master • https://github.com/flutter/flutter.git
Framework • revision c748f1a7aa (8 hours ago) • 2020-07-31 17:45:18 -0700
Engine • revision 280bbfc763
Tools • Dart 2.10.0 (build 2.10.0-2.0.dev bd528bfbd6)

Because that version of Flutter includes a full version of Dart, I have no separate Dart SDK installed.

For some reason, the webdev package wants to run the pub command from the cached Dart SDK which fails. Upon further inspection, this could be a problem with that package but it occurs because this plugin wanted to install webdev and I'm now stuck.

Can you capture a log when reproducing this and attach it here?

Run the Dart: Capture Logs command from the VS Code command palette
Untick Analysis Server but leave everything else ticked
Reproduce the issue
Attach the log

Thanks!

Here you go.

BTW, I'm clicking on "Run" label inside the source file. My project is configured for iOS, Android, web, and macOS.

@sma

@sma It looks like you're trying to fun a Flutter project using the Dart-web mechanism (using a "web/" path as the "program" in launch.json).

Can you clarify what type of project you're trying to run? For a Flutter app, your code generally lives inside the lib folder, not the web folder. Using "web" in "program" will force the Dart-web debugger that won't work with Fluter projects.

I don't think so. Is there a "magical" detecting going on that prevents me from using .../lib/web/minimarkdown.dart as a file name? I simply picked the folder name web for that subfolder because it contains dart code specific for the web version of my app. I would have expected that any name would work. Is there a similar problem if I'd have picked test?

I renamed the path to .../lib/bew/minimarkdown.dart (just to pick a different folder name) and now it works!

Is there a "magical" detecting going on that prevents me from using .../lib/web/minimarkdown.dart as a file name?

Oh, sorry - I didn't notice this was inside lib. I guess our detection of Dart web apps is a bit aggressive and should only consider web from the project root. I'll take a look, thanks!
