使用flutter_inappbrowser库iOS无法加载链接问题

flutter中使用webview，用了 flutter_inappbrowser 这个库，Android端显示正常，iOS出不来，最初网上找大多数都是说是因为没有添加对http请求的信任，需要在info里面添加

NSAppTransportSecurity

    NSAllowsArbitraryLoads
    

但是试过之后没有，后来一阵折腾，在官方库的文档中找到

• InAppWebView: Flutter Widget for adding an inline native WebView integrated into the flutter widget tree. To use InAppWebView class on iOS you need to opt-in for the embedded views preview by adding a boolean property to the app's Info.plist file, with the key io.flutter.embedded_views_preview and the value YES.

就是说在info添加 io.flutter.embedded_views_preview为 true 就行了

        ...
    io.flutter.embedded_views_preview
    

使用各种类库之前先看认真文档、说明很重要。
