How can I auto add 'const' in Flutter in Visual Studio Code?

Question

In Visual Studio Code, how can you automatically add const when you press (Ctrl + S)?

Answer 1

"editor.codeActionsOnSave": {
  "source.fixAll": true
}

gives error = Incorrect type. Expected "string".

so, use this

 "editor.codeActionsOnSave": {
            "source.fixAll": "explicit"
}

Answer 2

• Press Ctrl + Shift + P
• Search settings.json

  • Open the User Settings(Json)

    

  • Add the following code

     "editor.codeActionsOnSave": {
      "source.fixAll": true
    }

Answer 3

If there are things like constants or changes that can be improved, I recommend you apply for the same Flutter recommendations. Run this in your terminal and that's it.

dart fix --apply

Answer 4

To add an auto const feature when you save the file in Flutter in Visual Studio Code, you should follow these steps:

1. Press (Ctrl + P) then search for (settings.json) file.

2. Add this code line to there;

    "editor.codeActionsOnSave": {
        "source.fixAll": true
    }
