1、在flutter_plugin_platform_interface.dart类中增加方法 Future<String?> hello(){throwUnimplementedError('hello() has not been implemented.'); } 2、在flutter_plugin_method_channel.dart类中实现上面的方法 @overrideFuture<String?> hello()async{finalmsg =awaitmethodChannel.invokeMethod<String>('hello')...

另一方面,在单一组件中,Platform channels将开发的三端代码和部署粘合在一起。 Java/Kotlin ↔ Dart ↔ Objective-C/Swift In fact, it very often makes sense to package up a triad like this in a single code module, such as a Flutter plugin. This means that the need for arguments and results...
kernel_plugin_method_channel.dart -- kernel_plugin_platform_interface 的实现类,用于约定调用第三方平台方法入口。 其中getPlatformVersion,startKernel,startKernelMap,sum 字符串在第三方代码也必须一模一样,相当于用于约定交互的key @override Future<String?> getPlatformVersion() async { ...
plugin_example_platform_interface.dart:通信接口,plugin_example_method_channel是他的实现类,类似java的interface和impl; 示例中提供了一个获取当前系统平台版本号的一个方法getPlatformVersion,我们按照这个示例编写自己的方法即可,而plugin_example下的example工程则是插件使用示例项目,可以让你直接运行项目进行插件调试。
plugin是属于package的一种,区别是包含有原生的代码,比如Android的java或kotlin代码,或者iOS的Object-C或Swift代码。是通过Flutter Platform Channel实现的。 新建项目 方法一:命令行创建 --org后面为域名 --template后面设置成plugin表示为插件类型 最后为插件名 ...
