Flutter量化交易插件flutter_quanttide的使用

Flutter量化交易插件flutter-quanttide 的使用

flutter-quanttide 是一个用于量化交易的Flutter工具箱。它提供了一些实用的功能，帮助开发者快速构建与量化交易相关的应用。

使用步骤

1. 添加依赖

   在你的 pubspec.yaml 文件中添加 flutter_quanttide 依赖：

   dependencies:
     flutter:
       sdk: flutter
     flutter_quanttide: ^x.x.x # 请替换为最新版本号
   

2. 导入库

   在需要使用的文件中导入以下库：

   import 'package:flutter/material.dart';
   import 'package:flutter_quanttide/api_client.dart';
   import 'package:flutter_quanttide/src/widgets/network.dart';
   import 'package:flutter_quanttide/src/app.dart';
   

3. 配置环境变量

   创建一个 environment_config.dart 文件，并配置API根路径和路径：

   // environment_config.dart
   class EnvironmentConfig {
     static const String apiRoot = 'YOUR_API_ROOT'; // 替换为实际的API根路径
     static const String apiPath = 'YOUR_API_PATH'; // 替换为实际的API路径
   }
   

4. 创建主应用

   创建一个主应用类 MyApp 并设置其根视图：

   class MyApp extends StatelessWidget {
     const MyApp({Key? key}) : super(key: key);
   
     [@override](/user/override)
     Widget build(BuildContext context) {
       return MaterialApp(
         title: '量潮设计语言',
         theme: ThemeData(
           primarySwatch: Colors.blue,
         ),
         home: const MyHomePage(title: '量潮设计语言'),
         scrollBehavior: QuantTideScrollBehavior(),
       );
     }
   }
   

5. 创建主页

   创建一个主页类 MyHomePage，并实现数据获取逻辑：

   class MyHomePage extends StatefulWidget {
     const MyHomePage({Key? key, required this.title}) : super(key: key);
   
     final String title;
   
     [@override](/user/override)
     State<MyHomePage> createState() => _MyHomePageState();
   }
   
   class _MyHomePageState extends State<MyHomePage> {
     [@override](/user/override)
     Widget build(BuildContext context) {
       return Scaffold(
         appBar: AppBar(
           title: Text(widget.title),
         ),
         body: NetworkFutureBuilder(
           future: APIClient(
             apiRoot: EnvironmentConfig.apiRoot,
           ).request(
               httpMethod: 'GET',
               apiPath: EnvironmentConfig.apiPath,
           ),
           withData: (data) => const Text('请求成功'),
         ),
       );
     }
   }
   

6. 运行应用

   最后，确保你的 main.dart 文件中包含以下代码：

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

完整示例代码

import 'package:flutter/material.dart';
import 'package:flutter_quanttide/api_client.dart';
import 'package:flutter_quanttide/src/widgets/network.dart';
import 'package:flutter_quanttide/src/app.dart';

import 'environment_config.dart';

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

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: '量潮设计语言',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(title: '量潮设计语言'),
      scrollBehavior: QuantTideScrollBehavior(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key, required this.title}) : super(key: key);

  final String title;

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

class _MyHomePageState extends State<MyHomePage> {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: NetworkFutureBuilder(
        future: APIClient(
          apiRoot: EnvironmentConfig.apiRoot,
        ).request(
            httpMethod: 'GET',
            apiPath: EnvironmentConfig.apiPath,
        ),
        withData: (data) => const Text('请求成功'),
      ),
    );
  }
}
