How to add dart language to CodeRunner App in MacOS?

I want to add new language in coderunner app [MacOS]. which just works like DartPad. I installed flutter sdk. but I got this error message when I tried to compile the code after selecting the dart language which I added by Preferences/Languages/Add new language (+ symbol) :

/bin/sh: dart: command not found

Solution

Open CodeRunner app.
Go to CodeRunner/Preferences/Languages.
Click on the + button at the end of the languages to add another language.
Do the following steps to setup Dart as language mode in coderunner app :

Rename language name from Untitled to Dart.
Set Run Command as dart $filename.
Set File Extension as .dart.
Set Syntax mode as Dart.

5. Install Dart using HomeBrew in Terminal :

- brew tap dart-lang/dart
- brew install dart

If you get any error, try this before executing above commands :

export ALL_PROXY=$http_proxy:port

If you get any error like : Error: Your Command Line Tools are too outdated.

then try this : Update them from Software Update in System Preferences or run:

softwareupdate --all --install --force

If that doesn't show you any updates, run:

sudo rm -rf /Library/Developer/CommandLineTools
  sudo xcode-select --install

Now, let’s run sample dart code by selecting Dart as language and writing Hello World dart code :

Dart setup successfully :)
