Flutter云服务集成插件dart_nuntio_cloud的使用

dart_nuntio_cloud 是一个 Flutter 插件，用于集成云服务功能到你的 Flutter 应用中。它提供了与云服务的交互功能，如身份验证、数据存储、文件上传等。以下是如何在 Flutter 项目中使用 dart_nuntio_cloud 插件的步骤。

1. 添加依赖

首先，你需要在 pubspec.yaml 文件中添加 dart_nuntio_cloud 插件的依赖。

dependencies:
  flutter:
    sdk: flutter
  dart_nuntio_cloud: ^1.0.0  # 请根据实际情况填写最新版本号

然后运行 flutter pub get 来获取依赖。

2. 初始化插件

在你的 Flutter 应用中，你需要在应用启动时初始化 dart_nuntio_cloud 插件。通常可以在 main.dart 文件中进行初始化。

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

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  
  // 初始化插件
  await NuntioCloud.initialize(
    apiKey: 'YOUR_API_KEY',
    projectId: 'YOUR_PROJECT_ID',
  );
  
  runApp(MyApp());
}

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

3. 使用插件功能

dart_nuntio_cloud 提供了多种功能，例如身份验证、数据存储、文件上传等。以下是一些常见的使用示例。

3.1 用户身份验证

你可以使用 dart_nuntio_cloud 进行用户注册、登录和注销操作。

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

class AuthExample extends StatelessWidget {
  Future<void> signUp() async {
    try {
      await NuntioCloud.auth.signUp(
        email: 'user@example.com',
        password: 'password123',
      );
      print('User signed up successfully');
    } catch (e) {
      print('Error signing up: $e');
    }
  }

  Future<void> signIn() async {
    try {
      await NuntioCloud.auth.signIn(
        email: 'user@example.com',
        password: 'password123',
      );
      print('User signed in successfully');
    } catch (e) {
      print('Error signing in: $e');
    }
  }

  Future<void> signOut() async {
    try {
      await NuntioCloud.auth.signOut();
      print('User signed out successfully');
    } catch (e) {
      print('Error signing out: $e');
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Auth Example'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            ElevatedButton(
              onPressed: signUp,
              child: Text('Sign Up'),
            ),
            ElevatedButton(
              onPressed: signIn,
              child: Text('Sign In'),
            ),
            ElevatedButton(
              onPressed: signOut,
              child: Text('Sign Out'),
            ),
          ],
        ),
      ),
    );
  }
}

3.2 数据存储

你可以使用 dart_nuntio_cloud 进行数据的增删改查操作。

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

class DataStorageExample extends StatelessWidget {
  Future<void> addData() async {
    try {
      await NuntioCloud.database.collection('users').add({
        'name': 'John Doe',
        'email': 'john@example.com',
      });
      print('Data added successfully');
    } catch (e) {
      print('Error adding data: $e');
    }
  }

  Future<void> getData() async {
    try {
      var snapshot = await NuntioCloud.database.collection('users').get();
      snapshot.forEach((doc) {
        print('Document ID: ${doc.id}, Data: ${doc.data()}');
      });
    } catch (e) {
      print('Error getting data: $e');
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Data Storage Example'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            ElevatedButton(
              onPressed: addData,
              child: Text('Add Data'),
            ),
            ElevatedButton(
              onPressed: getData,
              child: Text('Get Data'),
            ),
          ],
        ),
      ),
    );
  }
}

3.3 文件上传

你可以使用 dart_nuntio_cloud 进行文件上传操作。

import 'package:flutter/material.dart';
import 'package:dart_nuntio_cloud/dart_nuntio_cloud.dart';
import 'package:image_picker/image_picker.dart';
import 'dart:io';

class FileUploadExample extends StatelessWidget {
  Future<void> uploadFile() async {
    final picker = ImagePicker();
    final pickedFile = await picker.getImage(source: ImageSource.gallery);

    if (pickedFile != null) {
      try {
        await NuntioCloud.storage.uploadFile(
          filePath: pickedFile.path,
          storagePath: 'uploads/image.jpg',
        );
        print('File uploaded successfully');
      } catch (e) {
        print('Error uploading file: $e');
      }
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('File Upload Example'),
      ),
      body: Center(
        child: ElevatedButton(
          onPressed: uploadFile,
          child: Text('Upload File'),
        ),
      ),
    );
  }
}

4. 运行应用

完成上述步骤后，你可以运行你的 Flutter 应用，并使用 dart_nuntio_cloud 插件来集成云服务功能。
