Neither F7 nor Shift+F7 runs a Dart program

#1

In installed the “dart” plugin and followed the instructions to create a project, etc. I wrote a Hello World program, which runs fine if I run it on the command line. But in Sublime Text, I’m supposed to be able to run it by pressing Shift+F7. Instead, I get this:

* Running /Users/barryburd/flutter_commandline_projects/sublime/darttut.dart
* (output starts below the next line)
==============================================================================
[Finished in 0.1s with exit code 255]
[cmd: ['/usr/local/Cellar/dart/2.3.1/libexec/bin/dart', '--checked', '/Users/barryburd/flutter_commandline_projects/sublime/darttut.dart']]
[dir: /Users/barryburd/flutter_commandline_projects/sublime]
[path: /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/barryburd/.local/bin:/opt/X11/bin:/Applications/VMware Fusion.app/Contents/Public:/Users/barryburd/eta:/Library/Frameworks/Mono.framework/Versions/Current/Commands:/Library/TeX/texbin:/Applications/Wireshark.app/Contents/MacOS]

How can I diagnose the problem?

The build output is showing that dart actually executed but returned exit code 255. It seems a little weird that it wouldn’t also output some sort of indication of why the error happened, though. Does the interpreter have some sort of --versose type command line option that might make it generate more info, or perhaps something that documents the return codes of the interpreter?

The --verbose option sounds like a good idea. But I don’t know how to turn it on for the Sublime Text Dart plugin.

From the documentation:

Analysis (errors and warnings) is deactivated by default. To activate this feature, open Packages/User/Dart - Plugin Settings.sublime-settings and set the dart_linter_active setting to true

To open this file, you can use the command palette (Ctrl+⇧+P), then select Preferences: Settings - User .

I don’t use this plugin so cannot answer any other questions about it.

I added

"dart_linter_active": "true"

to both the Settings - User and the Dart Settings files and restarted Sublime. The output is still the same with no additional messages.

This should be enabled by default but you could check that dart_enable_analysis_server is set to true in the settings. Failing that, you should contact the author of the package. As I mentioned, I don’t use the package, I am only reading the documentation.
