/// FlutterApi() 标记的#xff0c;是用于原生调用 Flutter 的方法
dependencies:
pigeon: ^10.0.0定义一个文件
/// 用于定于flutter和平台的桥接方法
/// HostApi() 标记的是用于 Flutter 调用原生的方法
/// FlutterApi() 标记的是用于原生调用 Flutter 的方法
/// async 如果原生的方法是步回调那种你就可以使用这个标记
/// 在项目根目录运行以下命令生成平台代码
/// dart run pigeon --input pigeons/messages.dartimport package:pigeon/pigeon.dart;ConfigurePigeon(PigeonOptions(dartOut: lib/pigeons/pigeon.dart,dartOptions: DartOptions(),// objcHeaderOut: ../isolarCloud/operation4ios/Flutter/SGFlutterBridge.h,// objcSourceOut: ../isolarCloud/operation4ios/Flutter/SGFlutterBridge.m,// objcOptions: ObjcOptions(),kotlinOut:../iSolarCloud/LibBase/src/main/java/com/isolarcloud/libbase/flutter/SGFlutterBridge.kt,kotlinOptions: KotlinOptions(),
))
class CommonParams {String? pageName;MapString?, Object?? arguments;
}
class ApiParams {String? url;MapString?, Object?? arguments;
}/// Flutter调用原生的Api全部放在一个抽象类中即可
HostApi()abstract class SGHostApi {/// push至原生页面参数页面名称、参数void pushNativePage(CommonParams params);/// pop出当前页面预留参数可通过params.pageName pop到指定页面void popPage(CommonParams? params);/// 通过Key获取本地化文本数据同步String getLocalizedText(String? key);/// Flutter通过URL和arguments调用原生端接口异步返回数据给Flutter端asyncMap requestNativeApi(ApiParams apiParams);/// 是否允许开启Native页面的原生手势返回效果void enablePopRecognizer(bool enable);
}运行命令行 dart run pigeon --input pigeons/messages.dart
接着可以运行下flutter pub get 的命令
自动会生成这个文件 里面会实现SGHostApi的定义的方法比如下面的方法就是自动生成
/// push至原生页面参数页面名称、参数
Futurevoid pushNativePage(CommonParams arg_params) async {final BasicMessageChannelObject? channel BasicMessageChannelObject?(dev.flutter.pigeon.isolarcloud_flutter.SGHostApi.pushNativePage, codec,binaryMessenger: _binaryMessenger);final ListObject?? replyList await channel.send(Object?[arg_params]) as ListObject??;if (replyList null) {throw PlatformException(code: channel-error,message: Unable to establish connection on channel.,);} else if (replyList.length 1) {throw PlatformException(code: replyList[0]! as String,message: replyList[1] as String?,details: replyList[2],);} else {return;}
}注意打开这个代码注释意思是在你Android项目的某个路径下生成SGFlutterBridge文件。
kotlinOut:../iSolarCloud/LibBase/src/main/java/com/isolarcloud/flutter/SGFlutterBridge.kt,
kotlinOptions: KotlinOptions(),然后会在上面这个路径下自动生成和原生的桥接方法这里执行的是Android的方法ios只需要打开 // objcHeaderOut: ../isolarCloud/operation4ios/Flutter/SGFlutterBridge.h,// objcSourceOut: ../isolarCloud/operation4ios/Flutter/SGFlutterBridge.m,// objcOptions: ObjcOptions(),我们先看看原生和flutter项目的依赖 在Android的项目settings.gradle中配置引用
setBinding(new Binding([gradle: this]))
evaluate(new File(settingsDir,../isolarcloud_flutter/.android/include_flutter.groovy)
)以上操作就把两个项目关联在一起了。下面是自动生成的桥接方法pigeon自动帮你实现

}同步或者异步的去调用自动生成的方法

}flutter中要使用的地方直接拿到成功和失败的回调即可

}按理来说这个GetxController类是用来访问网络的类这里用来和原生交互就这样子。
