Getting Access to the Run/Debug Configuration: Dart Command Line Application Dialog Box

Make sure the Dart development environment is configured, see Preparing for Dart Development.
Make sure the Node.js and Dart plugins are activated. The plugins are bundled with WebStorm and activated by default. If the plugins are not activated, enable them on the Plugins page of the Settings / Preferences Dialog as described in Enabling and Disabling Plugins.

Dart Command Line Application-Specific Configuration Settings

Item	Description
Name	In this text box, specify the name of the run/debug configuration.
Share	Select this check box to make the run/debug configuration available to other team members. The shared run/debug configurations are kept in separate xml files under `.idea\runConfigurations` folder, while the local run/debug configurations are kept in the `.idea\workspace.xml`. This check box is not available when editing the run/debug configuration defaults.
Dart file	In this text box, specify the Dart file to start the application from. The file must contain a `main()` method. Type the path to the file manually or click the Browse button and select the file in the dialog box that opens.
VM options	In this text box, specify the options to launch the Dart Virtual Machine with. When specifying the options, follow these rules: Use spaces to separate individual options, for example, `-client -ea -Xmx1024m`. If an option includes spaces, enclose the spaces or the argument that contains the spaces in double quotes, for example, `some" "arg` or `"some arg"`. If an option includes double quotes (e.g. as part of the argument), escape the double quotes by means of the backslashes, for example, `-Dmy.prop=\"quoted_value\"`.
Program arguments	In this text box, type the list of arguments to start the application with. Use the same format as for VM options.
Environment Variables	In this field, specify the environment variables for the NodeJS executable file, if applicable. Click the Browse button to the right of the field and configure a list of variables in the Environment Variables dialog box, that opens: To define a new variable, click the Add toolbar button and specify the variable name and value. To discard a variable definition, select it in the list and click the Delete toolbar button . Click OK, when ready The definitions of variables are displayed in the Environment variables read-only field with semicolons as separators. The acceptable variables are: `NODE_PATH`: A `:`-separated list of directories prefixed to the module search path. `NODE_MODULE_CONTEXTS`: Set to 1 to load modules in their own global contexts. `NODE_DISABLE_COLORS`: Set to 1 to disable colors in the REPL.
Working Directory	In this field, specify the working directory of the application. All references in the starting NodeJS application file, for example, includes, will be resolved relative to this folder, unless such references use full paths. By default, the field shows the project root folder. To change this predefined setting, choose the desired folder from the drop-down list, or type the path manually, or click the Browse button and select the location in the dialog box, that opens.

Toolbar

Item	Shortcut	Description
	`Alt+Insert`	Click this button to add a new configuration to the list.
	`Alt+Delete`	Click this button to remove the selected configuration from the list.
	`Ctrl+D`	Click this button to create a copy of the selected configuration.
	Edit defaults	Click this button to edit the default configuration templates. The defaults are used for newly created configurations.
or	`Alt+Up` or `Alt+Down`	Use these buttons to move the selected configuration or folder up and down in the list. The order of configurations or folders in the list defines the order in which configurations appear in the Run/Debug drop-down list on the main toolbar.
	Sort configurations	Click this button to sort configurations in alphabetical order.

Common options

Item Description

Name In this text box, specify the name of the current run/debug configuration. This field does not appear for the default run/debug configurations.

Defaults This node in the left-hand pane of the dialog box contains the default run/debug configuration settings. Select the desired configuration to change its default settings in the right-hand pane. The defaults are applied to all newly created run/debug configurations.

Select this check box to make the run/debug configuration available to other team members.

The shared run/debug configurations are kept in separate xml files under .idea\runConfigurations folder, while the local run/debug configurations are kept in the .idea\workspace.xml.

This check box is not available when editing the run/debug configuration defaults.

Single instance only

If this check box is selected, this run/debug configuration cannot be launched more than once.

Every time a new run/debug configuration is launched, WebStorm checks the presence of the other instances of the same run/debug configuration, and displays a confirmation dialog box. If you click OK in the confirmation dialog box, the first instance of the runner will be stopped, and the next one will take its place.

This makes sense when the usage of certain resources can cause conflicts, or when launching two run/debug configurations of the same type consumes too much of the CPU and memory resources.

If this check box is not selected, it is possible to launch as many instances of the runner as required. So doing, each runner will start in its own tab of the Run tool window.

Before launch

Specify which tasks must be performed before applying the run/debug configuration. The specified tasks are performed in the order they appear in the list.

Item	Keyboard shortcut	Description
	`Alt+Insert`	Click this icon to add a task to the list. Select the task to be added: Run External tool. Select this option to run an application which is external to WebStorm. In the dialog that opens, select the application or applications that should be run. If the necessary application is not defined in WebStorm yet, add its definition. For more information, see Configuring Third-Party Tools and External Tools. Run Another Configuration. Select this option to have another run/debug configuration executed. In the dialog that opens, select the configuration to run. This option is available only if you have already at least one run/debug configuration in the current project. Run File Watchers. Select this option to have WebStorm apply all the currently active file watchers, see Using File Watchers for details. Generate CoffeeScript Source Maps. Select this option to have the source maps for your CoffeeScript sources generated. In the dialog that opens, specify where your CoffeeScript source files are located. For more information, see CoffeeScript Support.
	`Alt+Delete`	Click this icon to remove the selected task from the list.
	`Enter`	Click this icon to edit the selected task. Make the necessary changes in the dialog that opens.
	`Alt+Up`	Click this icon to move the selected task one line up in the list.
	`Alt+Down`	Click this icon to move the selected task one line down in the list.
Show this page		Select this check box to have the run/debug configuration settings shown prior to actually starting the run/debug configuration.
Active tool window		Select this option if you want the Run/Debug tool windows to be activated automatically when you run/debug your application. This option is enabled by default.
