Flutter视图中嵌入iOS控件

前言

想要在flutter中展示iOS的视图很简单

使用UiKitView

• viewType：通信绑定的名字要和iOS中保持一致
• onPlatformViewCreated：回调的是创建iOS视图的动态id
• creationParams：创建视图时需要传递的参数
• creationParamsCodec：将 creationParams 编码后再发送给平台侧

视图绑定

在iOS中需要将视图进行绑定

XJPLPlayerFactory *factory = [[XJPLPlayerFactory alloc]initWithMessager:registrar.messenger];
[registrar registerViewFactory:factory withId:@"plugins.flutter.io/xj_pl_player_view"];
