在vsCode中格式化.dart文件(flutter)

我似乎无法设置自动格式化程序。

我有Dart和Flutter的vsCode扩展。

这是我的settings.json文件：

{
"workbench.iconTheme": "material-icon-theme",
"terminal.integrated.shell.windows": "C:\Program Files\Git\bin\bash.exe",
"debug.openDebug": "openOnDebugBreak",
"[javascript]": {
"editor.defaultFormatter": "esbenp.prettier-vscode",
"editor.formatOnSave": true
},
"explorer.confirmDelete": false,
"javascript.updateImportsOnFileMove.enabled": "always",
"typescript.updateImportsOnFileMove.enabled": "always",
"[dart]": {
"editor.formatOnSave": true,
"editor.formatOnType": true,
"editor.rulers": [80],
"editor.selectionHighlight": false,
"editor.suggest.snippetsPreventQuickSuggestions": false,
"editor.suggestSelection": "first",
"editor.tabCompletion": "onlySnippets",
"editor.wordBasedSuggestions": false,
"editor.defaultFormatter": "Dart-Code.flutter",
},

"dart.flutterHotReloadOnSave": "always",
"editor.defaultFormatter": "Dart-Code.dart-code",
"editor.formatOnSave": true,
}

我希望格式化程序在行尾添加;和,，并在需要的地方添加/删除间距和缩进。我缺什么了吗？
