Question

我正在尝试在 Flutter 中实现支付 SDK，它在 Android 端成功运行，但在 iOS 中实现它时遇到了麻烦。

付款成功后我收到回复

 func qpResponse(_ response: NSDictionary) {
                        print("Response Inside customer app:",response)
                //Perform your actions with the response
  
  }

如何将其发送到 Flutter？

Answer 1

flutter EventCHannel 就是你想要的。

oc、快速：

- (void)initMethodChannel{
self.methodChannel = [FlutterMethodChannel methodChannelWithName:@"MethodChannelPlugin" binaryMessenger:self.flutterViewController];
MainViewController*  __weak weakSelf = self;
[self.methodChannel setMethodCallHandler:^(FlutterMethodCall * _Nonnull call, FlutterResult  _Nonnull result) {
    if ([@"send" isEqualToString:call.method]) {
        result([NSString stringWithFormat:@"MethodChannelPlugin收到：%@",call.arguments]);//返回结果给Dart);
        [weakSelf sendShow:call.arguments];
    }
  }];
}

飞镖：

import 'package:flutter/services.dart';
...
static const MethodChannel _methodChannelPlugin =
      const MethodChannel('MethodChannelPlugin');
...
String response;
    try {
        response = await _methodChannelPlugin.invokeMethod('send', value);
    } on PlatformException catch (e) {
      print(e);
    }
...

上述解决方案的 Swift 版本：

// 导入 Flutter //导入 FlutterPluginRegistrant

let flutterEngine = FlutterEngine(name: "io.flutter", project: nil)
        flutterEngine?.run(withEntrypoint: nil)
        GeneratedPluginRegistrant.register(with: self.flutterEngine!)
        let flutterViewController = FlutterViewController(engine: flutterEngine, nibName: nil, bundle: nil)

        let flutterMethodChannel = FlutterMethodChannel(name: "MethodChannelPlugin",
                                                        binaryMessenger: flutterViewController.binaryMessenger)


        flutterMethodChannel.setMethodCallHandler { _, _ in
            //receive call here Swift
        }

如何将委托函数的响应传递给 Swift 中的颤振？
