Flutter功能未明确定义插件pedant的使用

Pedant 插件介绍

Pedant 是一个严格的静态分析器和脚本，用于格式化 Dart 代码。它旨在解决项目设计和支持阶段的问题。以下是其主要功能：

• 自动修复检测到的 lint 错误；
• 按字母顺序排序 .arb 文件中的字段；
• 按字母顺序排序 .dart 文件中的导入、导出和部分声明；
• 将 .dart 文件中的相对导入声明转换为绝对路径；
• 删除 .dart 文件中未使用的导入声明；
• 按字母顺序排序 pubspec.yaml 文件中的 dependencies、dev_dependencies 和 dependency_overrides 关键字；
• Dart 代码格式化。

安装和配置

1. 安装 在 pubspec.yaml 文件的 dev_dependencies 部分添加两个包：

   dev_dependencies:
     custom_lint: ^latest_version
     pedant: ^latest_version
   

2. 配置 当前默认配置如下：

   custom_lint:
     rules:
       - pedant:
           add_bloc_cubit_event_state_file: true
           add_bloc_cubit_state_postfix: true
           add_bloc_cubit_state_sealed: true
           add_bloc_event_postfix: true
           add_bloc_event_sealed: true
           add_bloc_postfix: true
           add_class_postfix_by_keyword_list: null
           add_class_postfix_by_path_list: null
           add_class_prefix_by_keyword_list: null
           add_class_prefix_by_path_list: null
           add_comma: true
           add_const_constructor: true

           add_extension_postfix: true
           add_if_braces: true
           add_mixin_postfix: true
           add_override: true
           add_this: true

           delete_bloc_cubit_dependent_bloc_cubit: true
           delete_bloc_cubit_dependent_flutter: true
           delete_bloc_cubit_public_property: true
           delete_class_postfix_list:
             - Impl
             - Implementation
             - Model
           delete_class_prefix_list: null
           delete_function_list:
             - print

           edit_function_private_named_parameter: true
           edit_function_public_named_parameter: true

           priority: 100
   

3. 运行脚本 运行脚本：

   dart run pedant
   

示例代码

// import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  // This widget is the root of your application. It theme is set and used by
  // the MaterialApp.
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({required this.title});

  final String title;

  [@override](/user/override)
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;

  void _incrementCounter() {
    setState(() {
      _counter++;
    });
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Theme.of(context).colorScheme.inversePrimary,
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            const Text(
              'You have pushed the button this many times:',
            ),
            Text(
              '$_counter',
              style: Theme.of(context).textTheme.headlineMedium,
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        tooltip: 'Increment',
        child: const Icon(Icons.add),
      ), // This trailing comma makes auto-formatting nicer for build methods.
    );
  }
