Flutter使用webview

使用插件flutter_webview_plugin
ios在ios/Runner/Info.plist中添加如下代码

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

安卓插件说明文档上没说，但直接运行可能会报的ERR_CLEARTEXT_NOT_PERMITTED异常。
在android/app/src/main/res/xml文件架下新建文件network_security_config.xml

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config cleartextTrafficPermitted="true">
        <trust-anchors>
            <certificates src="system" />
        </trust-anchors>
    </base-config>
</network-security-config>

修改android/app/src/main/AndroidManifest.xml文件

<application
  .........
  android:usesCleartextTraffic="true"
  android:networkSecurityConfig="@xml/network_security_config">

使用

WebviewScaffold(
      url: url,
      ignoreSSLErrors: true,
      withJavascript: true,
      appBar: new AppBar(
        centerTitle: true,
        elevation: 0,
        title: Text("网页"),
      ),
    )
