flutter中使用webview，用了 flutter_inappbrowser 這個(gè)庫(kù)，Android端顯示正常，iOS出不來(lái)，最初網(wǎng)上找大多數(shù)都是說(shuō)是因?yàn)闆]有添加對(duì)http請(qǐng)求的信任，需要在info里面添加

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

但是試過(guò)之后沒有，后來(lái)一陣折騰，在官方庫(kù)的文檔中找到

• 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.

就是說(shuō)在info添加 io.flutter.embedded_views_preview為 true 就行了

<plist version="1.0">
<dict>
        ...
    <key>io.flutter.embedded_views_preview</key>
    <true/>
</dict>
</plist>

使用各種類庫(kù)之前先看認(rèn)真文檔、說(shuō)明很重要。
