Flutter模拟Firebase Functions插件mock_firebase_functions的使用

特性

该插件可用于模拟FirebaseFunctions调用。它最好与依赖注入一起使用。

开始使用

运行 flutter pub add mock_firebase_functions 命令后，你就可以开始使用了。

使用示例

以下是一个完整的示例，展示了如何使用 mock_firebase_functions 插件来模拟Firebase Functions调用。

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

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text("Mock Firebase Functions Demo"),
        ),
        body: Center(
          child: MockFirebaseFunctionsDemo(),
        ),
      ),
    );
  }
}

class MockFirebaseFunctionsDemo extends StatefulWidget {
  @override
  _MockFirebaseFunctionsDemoState createState() => _MockFirebaseFunctionsDemoState();
}

class _MockFirebaseFunctionsDemoState extends State<MockFirebaseFunctionsDemo> {
  String _result = "未执行";
  
  @override
  Widget build(BuildContext context) {
    return Column(
      mainAxisAlignment: MainAxisAlignment.center,
      children: [
        ElevatedButton(
          onPressed: () async {
            // 创建一个MockFirebaseFunctions实例
            final functions = MockFirebaseFunctions();

            // 模拟一个名为'function1'的函数，返回'Hello World'
            functions.mock('function1', (body) {
              return 'Hello World';
            });

            // 调用模拟的函数
            final response = await functions.httpsCallable('function1').call({});

            // 更新UI以显示结果
            setState(() {
              _result = response.data;
            });
          },
          child: Text("调用模拟函数"),
        ),
        SizedBox(height: 20),
        Text(_result),
      ],
    );
  }
}

代码解释

1. 导入必要的包：

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

2. 创建应用程序入口点：

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

3. 定义应用主界面：

   class MyApp extends StatelessWidget {
     @override
     Widget build(BuildContext context) {
       return MaterialApp(
         home: Scaffold(
           appBar: AppBar(
             title: Text("Mock Firebase Functions Demo"),
           ),
           body: Center(
             child: MockFirebaseFunctionsDemo(),
           ),
         ),
       );
     }
   }
   

4. 创建模拟函数调用的界面：

   class MockFirebaseFunctionsDemo extends StatefulWidget {
     @override
     _MockFirebaseFunctionsDemoState createState() => _MockFirebaseFunctionsDemoState();
   }
   
   class _MockFirebaseFunctionsDemoState extends State<MockFirebaseFunctionsDemo> {
     String _result = "未执行";
   
     @override
     Widget build(BuildContext context) {
       return Column(
         mainAxisAlignment: MainAxisAlignment.center,
         children: [
           ElevatedButton(
             onPressed: () async {
               // 创建一个MockFirebaseFunctions实例
               final functions = MockFirebaseFunctions();
   
               // 模拟一个名为'function1'的函数，返回'Hello World'
               functions.mock('function1', (body) {
                 return 'Hello World';
               });
   
               // 调用模拟的函数
               final response = await functions.httpsCallable('function1').call({});
   
               // 更新UI以显示结果
               setState(() {
                 _result = response.data;
               });
             },
             child: Text("调用模拟函数"),
           ),
           SizedBox(height: 20),
           Text(_result),
         ],
       );
     }
   }
