Flutter潜水日志管理插件venturedive_flutter_cli的使用

当然，关于 venturedive_flutter_cli 的使用，我们可以直接通过代码示例来展示如何在 Flutter 项目中集成和使用这个插件。假设 venturedive_flutter_cli 插件提供了一系列用于管理潜水日志的功能，比如创建、读取、更新和删除日志条目。以下是一个简化的示例代码，展示了如何使用该插件。

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

dependencies:
  flutter:
    sdk: flutter
  venturedive_flutter_cli: ^最新版本号

然后运行 flutter pub get 来获取依赖项。

接下来，在你的 Flutter 项目中，你可以这样使用 venturedive_flutter_cli 插件：

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

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Dive Log Manager',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: DiveLogManager(),
    );
  }
}

class DiveLogManager extends StatefulWidget {
  @override
  _DiveLogManagerState createState() => _DiveLogManagerState();
}

class _DiveLogManagerState extends State<DiveLogManager> {
  final VentureDiveClient _client = VentureDiveClient();
  List<DiveLog> _diveLogs = [];

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

  Future<void> _fetchDiveLogs() async {
    try {
      _diveLogs = await _client.fetchDiveLogs();
      setState(() {});
    } catch (e) {
      print('Error fetching dive logs: $e');
    }
  }

  Future<void> _addDiveLog(String location, double depth, DateTime dateTime) async {
    try {
      DiveLog newLog = DiveLog(location: location, depth: depth, dateTime: dateTime);
      await _client.addDiveLog(newLog);
      _fetchDiveLogs();
    } catch (e) {
      print('Error adding dive log: $e');
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Dive Log Manager'),
      ),
      body: Padding(
        padding: const EdgeInsets.all(16.0),
        child: Column(
          children: [
            Expanded(
              child: ListView.builder(
                itemCount: _diveLogs.length,
                itemBuilder: (context, index) {
                  DiveLog log = _diveLogs[index];
                  return ListTile(
                    title: Text('Location: ${log.location}'),
                    subtitle: Text('Depth: ${log.depth.toStringAsFixed(1)}m, Date: ${log.dateTime}'),
                  );
                },
              ),
            ),
            TextField(
              decoration: InputDecoration(labelText: 'Location'),
              onEditingComplete: () {
                // Assume we have depth and dateTime values somehow
                double depth = 30.0; // Example depth
                DateTime dateTime = DateTime.now(); // Example date and time
                _addDiveLog(this.text, depth, dateTime);
                this.clear(); // Clear the text field after submission
              },
            ),
            SizedBox(height: 16),
            ElevatedButton(
              onPressed: () {
                // Here you could add a dialog to input depth and date time, for simplicity we skip it
                // For now, just clear the text field focus
                FocusScope.of(context).unfocus();
              },
              child: Text('Add Dive Log'),
            ),
          ],
        ),
      ),
    );
  }
}

// Assuming the plugin provides these data models and client methods
class DiveLog {
  String location;
  double depth;
  DateTime dateTime;

  DiveLog({required this.location, required this.depth, required this.dateTime});
}

class VentureDiveClient {
  Future<List<DiveLog>> fetchDiveLogs() async {
    // Implement API call to fetch dive logs
    // For demo purposes, returning an empty list
    return [];
  }

  Future<void> addDiveLog(DiveLog log) async {
    // Implement API call to add a new dive log
    // For demo purposes, do nothing
  }
}

请注意，上面的代码是一个简化的示例，实际使用中，VentureDiveClient 类的 fetchDiveLogs 和 addDiveLog 方法需要实现具体的 API 调用逻辑。由于 venturedive_flutter_cli 插件的具体实现细节未知，你可能需要查阅该插件的官方文档来了解如何正确地进行 API 调用。

此外，UI 部分也可能需要根据实际需求进行调整，比如添加更多的输入字段来收集潜水日志的详细信息，或者实现更复杂的错误处理和用户反馈机制。
