当然，以下是一个关于如何使用Flutter巡逻管理插件 patrol_cli 的示例代码案例。这个插件假定用于管理和调度巡逻任务，但请注意，由于这是一个假设性的插件，具体实现细节可能需要根据实际插件的API文档进行调整。

首先，确保你已经在 pubspec.yaml 文件中添加了 patrol_cli 依赖：

dependencies:
  flutter:
    sdk: flutter
  patrol_cli: ^x.y.z  # 替换为实际版本号

然后运行 flutter pub get 来获取依赖。

接下来是一个简单的示例代码，展示如何使用 patrol_cli 插件来管理巡逻任务。

main.dart

import 'package:flutter/material.dart';
import 'package:patrol_cli/patrol_cli.dart';  // 假设这是插件的导入路径

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Patrol Management',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: PatrolManagementScreen(),
    );
  }
}

class PatrolManagementScreen extends StatefulWidget {
  @override
  _PatrolManagementScreenState createState() => _PatrolManagementScreenState();
}

class _PatrolManagementScreenState extends State<PatrolManagementScreen> {
  final PatrolCli _patrolCli = PatrolCli();
  List<PatrolTask> _patrolTasks = [];

  @override
  void initState() {
    super.initState();
    _fetchPatrolTasks();
  }

  Future<void> _fetchPatrolTasks() async {
    try {
      _patrolTasks = await _patrolCli.fetchPatrolTasks();
      setState(() {});
    } catch (e) {
      print('Error fetching patrol tasks: $e');
    }
  }

  Future<void> _addPatrolTask(String description, DateTime startTime, DateTime endTime) async {
    try {
      PatrolTask newTask = await _patrolCli.addPatrolTask(
        description: description,
        startTime: startTime,
        endTime: endTime,
      );
      setState(() {
        _patrolTasks.add(newTask);
      });
    } catch (e) {
      print('Error adding patrol task: $e');
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Patrol Management'),
      ),
      body: Padding(
        padding: const EdgeInsets.all(8.0),
        child: Column(
          children: [
            Expanded(
              child: ListView.builder(
                itemCount: _patrolTasks.length,
                itemBuilder: (context, index) {
                  PatrolTask task = _patrolTasks[index];
                  return ListTile(
                    title: Text('Task ${task.id}: ${task.description}'),
                    subtitle: Text('From ${task.startTime} to ${task.endTime}'),
                  );
                },
              ),
            ),
            SizedBox(height: 20),
            TextField(
              decoration: InputDecoration(labelText: 'Description'),
              onEditingComplete: () async {
                DateTime startTime = DateTime.now().add(Duration(minutes: 15));
                DateTime endTime = startTime.add(Duration(hours: 1));
                String description = 'New Patrol Task'; // 这里可以从TextField获取实际输入
                await _addPatrolTask(description, startTime, endTime);
              },
            ),
            SizedBox(height: 10),
            ElevatedButton(
              onPressed: () {
                // 触发TextField的onEditingComplete
                FocusScope.of(context).requestFocus(FocusNode());
              },
              child: Text('Add Task'),
            ),
          ],
        ),
      ),
    );
  }
}

class PatrolTask {
  final int id;
  final String description;
  final DateTime startTime;
  final DateTime endTime;

  PatrolTask({required this.id, required this.description, required this.startTime, required this.endTime});
}

假设的 PatrolCli 类

由于 patrol_cli 是一个假设的插件，这里提供一个简化的模拟类来表示其可能的功能：

import 'dart:convert';
import 'package:http/http.dart' as http;

class PatrolCli {
  static const String apiUrl = 'https://api.example.com/patrol';

  Future<List<PatrolTask>> fetchPatrolTasks() async {
    final response = await http.get(Uri.parse('$apiUrl/tasks'));
    if (response.statusCode == 200) {
      List<dynamic> body = jsonDecode(response.body);
      return body.map((dynamic item) => PatrolTask.fromJson(item)).toList();
    } else {
      throw Exception('Failed to fetch patrol tasks');
    }
  }

  Future<PatrolTask> addPatrolTask({required String description, required DateTime startTime, required DateTime endTime}) async {
    Map<String, dynamic> data = {
      'description': description,
      'startTime': startTime.toIso8601String(),
      'endTime': endTime.toIso8601String(),
    };

    final response = await http.post(Uri.parse('$apiUrl/tasks'), body: jsonEncode(data), headers: {
      'Content-Type': 'application/json',
    });
    if (response.statusCode == 201) {
      Map<String, dynamic> body = jsonDecode(response.body);
      return PatrolTask.fromJson(body);
    } else {
      throw Exception('Failed to add patrol task');
    }
  }
}

extension PatrolTaskFromJson on PatrolTask {
  factory PatrolTask.fromJson(Map<String, dynamic> json) {
    return PatrolTask(
      id: json['id'] as int,
      description: json['description'] as String,
      startTime: DateTime.parse(json['startTime'] as String),
      endTime: DateTime.parse(json['endTime'] as String),
    );
  }
}

请注意，上述代码是一个简化的示例，实际使用中你可能需要根据 patrol_cli 插件的API文档进行具体实现和调整。特别是API端点、请求参数和数据结构可能有所不同。
