Flutter数据伪造插件egycoder_faker的使用

Flutter数据伪造插件egycoder_faker的使用

egycoder_faker 是 egycoder 框架的一个包，它帮助程序员生成临时数据，如（图像、姓名、地址等）。

示例代码

// ignore_for_file: unused_local_variable

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

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

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

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

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    // person faker
    final firstName = faker.person.firstName;
    final lastName = faker.person.lastName;
    final fullName = faker.person.name;

    // address faker
    final streetName = faker.address.neighborhood;
    final coordinates = faker.address.coordinates;

    // company faker
    final restaurantName = faker.company.restaurant;

    // image faker
    final svgImage = faker.image.svg;
    final networkImage = faker.image.network(
      width: 200,
      height: 200,
      keywords: ['cats', 'black'],
    );

    // internet faker
    final ip = faker.internet.ipAddress;
    final email = faker.internet.email;

    // lorem faker
    final word = faker.lorem.word;
    final words = faker.lorem.words(10);
    final sentence = faker.lorem.sentence;
    final sentences = faker.lorem.sentences(10);

    // public faker
    final color = faker.color;
    final decimal = faker.decimal(max: 10, min: 5);
    final elementFromList = faker.element(['1', '2']);
    final integer = faker.integer(min: 5, max: 10);
    final keyFromMap = faker.mapKey({'key1': 'value1', 'key2': 'value2'});
    final valueFromMap = faker.mapValue({'key1': 'value1', 'key2': 'value2'});
    final longNumber = faker.numberOfLength(20);
    final listOfNumbers = faker.numbers(max: 50, length: 10);

    return const SizedBox.shrink();
  }
}

完整示例代码解析

1. 导入库

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

2. 主应用入口

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

3. 定义 MyApp 类

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

4. 定义 MyHomePage 类

   class MyHomePage extends StatefulWidget {
     const MyHomePage({super.key, required this.title});
   
     final String title;
   
     @override
     State<MyHomePage> createState() => _MyHomePageState();
   }
   

5. 实现 _MyHomePageState 类

   class _MyHomePageState extends State<MyHomePage> {
     @override
     Widget build(BuildContext context) {
       // 使用 Faker 生成数据
       final firstName = faker.person.firstName;
       final lastName = faker.person.lastName;
       final fullName = faker.person.name;
   
       final streetName = faker.address.neighborhood;
       final coordinates = faker.address.coordinates;
   
       final restaurantName = faker.company.restaurant;
   
       final svgImage = faker.image.svg;
       final networkImage = faker.image.network(
         width: 200,
         height: 200,
         keywords: ['cats', 'black'],
       );
   
       final ip = faker.internet.ipAddress;
       final email = faker.internet.email;
   
       final word = faker.lorem.word;
       final words = faker.lorem.words(10);
       final sentence = faker.lorem.sentence;
       final sentences = faker.lorem.sentences(10);
   
       final color = faker.color;
       final decimal = faker.decimal(max: 10, min: 5);
       final elementFromList = faker.element(['1', '2']);
       final integer = faker.integer(min: 5, max: 10);
       final keyFromMap = faker.mapKey({'key1': 'value1', 'key2': 'value2'});
       final valueFromMap = faker.mapValue({'key1': 'value1', 'key2': 'value2'});
       final longNumber = faker.numberOfLength(20);
       final listOfNumbers = faker.numbers(max: 50, length: 10);
   
       return const SizedBox.shrink();
     }
   }
