Is There anyway to execute multiple commands in vscode keybindings.json?

Question

I need to execute multiple commands in keybindings.json in vscode to be able to log variable name, filename and the variable value.

ex in dart

double x = 2.2;
print("main.dart -> x $x");

the default behavior is to insertSnippet in the same line but i need to go to add new line below my variable then insert my custom snippet.

In addition i tried macros and multi-command. Unforgettably i couldn't reach the VSCode environment variables like TM_FILENAME_BASE and CLIPBOARD. They just print as a plane text something like

double x = 2.2;
print("$TM_FILENAME_BASE x $x") 

Not able to resolve the env var to it's value.

this is from mutli-command extension settings.json

"multiCommand.commands": [
        {
            "command": "myCommand",
            "sequence": [
                "cursorDown",
                "insertSnippet",
                {
                    "command": "type",
                    "args": {
                        "text": "print(\" log-> ${TM_FILENAME_BASE} -> 
                       ${TM_SELECTED_TEXT} -> ${${TM_SELECTED_TEXT}} \" );"
                    }
                }
            ]
        },
    ],

and this one from keybindings.json

{
     "key": "alt+p",
     "command": "editor.action.insertSnippet",
     "when": "editorTextFocus && resourceExtname == .dart",
     "args": {
         "snippet": "print(\" log-> ${TM_FILENAME_BASE} -> ${TM_SELECTED_TEXT} -> ${${TM_SELECTED_TEXT}} \" );"
     }
}

SOLUTION This is a tweaked solution for my issue inspired by Mark

from settings.json

 "multiCommand.commands": [
        {
            "command": "multiCommand.printVariable",
            "sequence": [
                "editor.action.clipboardCopyAction", // Copy the selected to the clipboard 
                "editor.action.insertLineAfter", 
                {
                    "command": "editor.action.insertSnippet",
                    "args": {
                        "snippet": "print(\"${TM_FILENAME_BASE} -> ${CLIPBOARD} -> ${${CLIPBOARD}}\");" // then add it here 
                    }
                },
            ]
        },
    ],

from keybindings.json

 {
        "key": "alt+p",
        "command": "extension.multiCommand.execute",
        "args": {
            "command": "multiCommand.printVariable"
        },
        "when": "editorTextFocus && resourceExtname == .dart"
 }

If you select your variable, this gives your desired output:

"multiCommand.commands": [

  {
    "command": "multiCommand.printVariable",

    "sequence": [
      "editor.action.clipboardCopyAction",
      "editor.action.insertLineAfter",
      {
        "command": "editor.action.insertSnippet",
        "args": {
          "snippet": "print(\"${TM_FILENAME_BASE} -> "
        }
      },
      "editor.action.clipboardPasteAction",
      {
        "command": "type",
        "args": {
          "text": " $"
        }
      },
      "editor.action.clipboardPasteAction",
      {
        "command": "type",
        "args": {
          "text": "\");"
        }
      },
    ]
  },

You used the ${TM_FILENAME_BASE} so I did as well - it will strip off the extension - but you showed main.dart as part of your desired output so perhaps you wanted TM_FILENAME?

and your keybinding:

{
  "key": "alt+p",    // or whichever keybinding you choose
  "command": "extension.multiCommand.execute",
  "args": { "command": "multiCommand.printVariable" },
  "when": "editorTextFocus && resourceExtname == .dart" 
},

Similarly to my answer How to create a shortcut to print a variable (vscode)

if your input is of the general form

double x = 2.2;  // where the desired variable is right before an `=`

you can simplify this alot and only use the following keybinding (and no macro) with your cursor at the end of the line - no selection:

{
  "key": "alt+p",
  "command": "editor.action.insertSnippet",
  "args": {
              // works with cursor end of line, no selection
    "snippet": "\nprint(\"${TM_FILENAME_BASE} -> ${TM_CURRENT_LINE/\\s*\\w*\\b\\s*(.*?)\\s*=.*/$1 $$1\");/}",
  },
   "when": "editorTextFocus && resourceExtname == .dart" 
},

Demo of both approaches. First with the selection and macro. Second, no selection, cursor at end of line and simple snippet.

Note I am in my keybindings.json file and so ${TM_FILENAME_BASE} = keybindings.
