如何在顫動中實作這種連接的點布局？

我想創建這樣的東西：-

我怎樣才能實作這些作為標簽欄的連接點布局。有沒有可用的軟體包？

Stepper無需任何包即可在 Flutter 中創建Horizo??ntal

檢查這個包：im_stepper，它有很多自定義選項。

功能名稱是“步進器”，您可以使用很少的參考來實作這一點https://medium.flutterdevs.com/stepper-widget-in-flutter-37ce5b45575b這是如何在顫振和其他中使用步進器的教程說明我認為與您的 UI 設計非常相似的步進器可在https://stackoverflow.com/a/71656978/13497264上找到

這是簡單的步進器（cr：GeeksforGeeks）

class _MyHomePageState extends State<MyHomePage> {
   
  // Here we have created list of steps that
  // are required to complete the form
   List<Step> stepList() => [
        const Step(title: Text('Account'), content: Center(child: Text('Account'),)),
         const Step(title: Text('Address'), content: Center(child: Text('Address'),)),
          const Step(title: Text('Confirm'), content: Center(child: Text('Confirm'),))
   ];
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        centerTitle: true,
        backgroundColor: Colors.green,
        title: const Text('GeeksforGeeks',style: TextStyle(color: Colors.white), ),
      ),
       
      // Here we have initialized the stepper widget
      body: Stepper(
        steps: stepList(),
      )
    );
  }
}

您可以通過將步進器設定為水平模式來將其設定為水平線：

body: Stepper(
         type: StepperType.horizontal,
         steps: stepList(),
      )
