improve Dart/Flutter highlighting

I want local variables (like authResult) to be amber and class members (like _auth) to be deep orange, as in Android Studio: Current VS Code highlighting. All variables are boring white:

Also, grey background is too bright. I found dark navy background is more pleasant to eye. Maybe something like these:

    "workbench.colorCustomizations": {
        "[One Dark Pro]": {
            "editor.background": "#191a20",    
            "editor.lineHighlightBackground": "#22232b",
            "editor.selectionBackground": "#363844",                                         
        }
    },

you can set these in your setting.json to check the effect(need reload when first set)

"editor.semanticTokenColorCustomizations": {
    "rules": {
      "variable:dart":{
        "foreground": "#D19A66"
      },
      "property:dart":{
        "foreground": "#D19A66"
      },
      "annotation:dart":{
        "foreground": "#D19A66"
      },
      "parameter:dart":{
        // "foreground": "#abb2bf"
      },
    }
  },
  "editor.semanticHighlighting.enabled": true,
  "dart.previewLsp": true,

and use this the check the code’s scope

also @Binaryify i’d suggest going back to red for dart instead of amber, half the file looks yellow/orange now
