DART SDK not found

[septimagus]

I've tried using vim-lsc-dart as a plugin on neovim (latest version). I've got Flutter up and running, it is in my path and I am able to run it from the terminal. As soon as I display a .dart file, neovim says "DART SDK not found". I tried running the dart analyzer snapshot using the vim lsc plugin. It seems to run on the terminal but doesn't really do anything much to the .dart file. Any way to get it working? Thanks in advance

I would expect the error to be Could not find the Dart SDK. - did you copy/paste that message?

When you are in nvim are you able to run !dart --help?

"Could not find either a dart or flutter command. Your $PATH must contain either the Dart of Flutter bin directory". This is what shows up now. Flutter and Flutter doctor are still working from the terminal, I tried running the !dart --help in nvim and this is what I get

"Usage: dart [] []

This set is subject to change.
Please see these options (--help --verbose) for further documentation.

I did "EXPORT" my flutter path to the bashrc, when I installed flutter. Could this be an issue? My PATH variable does have flutter/bin at the end of it though.

Flutter and Flutter doctor are still working from the terminal

How do you normally run nvim? Can you try running it from the terminal where the flutter command is working?

I tried running the !dart --help in nvim and this is what I get

That's the output I would expect if your $PATH is set up correctly, however...

"Could not find either a dart or flutter command. Your $PATH must contain either the Dart of Flutter bin directory".

I added this error with a specific check for where I would expect :! dart would not work. I don't know what situation would lead to :! dart executing dart, while executable('dart') is false...

vim-lsc-dart/autoload/lsc/dart.vim

Lines 50 to 51 in 3817ae1

	if !executable('dart') && !executable('flutter')
	echoerr 'Could not find either a `dart` or `flutter` command. '

I'm running it from the same terminal, tried two different terminal emulators and two versions of nvim(both stable)too. Do you think there is any way I can manually set the path that the lsc-dart plugin looks into (for a test case)?

[natebosch]

I'm not sure what other solutions to look for here. I suppose one workaround we could try is adding a configuration to specify the path to the SDK directly instead of searching for it.

Can you try out the branch dart-sdk-path-config and then add the path to your Dart SDK in g:lsc_dart_sdk_path?

#17

It's working, all the errors have disappeared and auto complete is showing suggestions, thanks a bunch. Is there any way I could enable closing labels or perhaps, could you point me in the right direction with regards to the documentation of such settings?

Awesome! I'll merge that PR.

Is there any way I could enable closing labels

Not currently. I filed #18 as a feature request, however its not likely I'll get to it soon since I use vim, not nvim, and there is no support for virtual text in vim.

I had the same issue with a strange solution.

The following was in my .bashrc:
export PATH="$PATH:~/flutter/bin"
and it could not find dart or flutter, even though I could execute the command from shell and with :!dart in nvim.

Then I changed it in the .bashrc to export PATH="$PATH:/home/<my_user_name>/flutter/bin"
and now it's working.
