如果我的插件不适用于webview\u flatter
,你也可以试试我的插件。
它是一个flatter插件,允许您添加内联网络视图或打开应用程序内浏览器窗口,并具有许多事件、方法和选项来控制网络视图
下面是一个使用initialData:InAppWebViewInitialData()
属性在WebView中插入初始HTML字符串的示例:
导入'dart:async';
进口“包装:颤振/材料.省道”;
导入“包:flatter_inappwebview/flatter_inappwebview.dart”;
Future main()异步{
WidgetsFlutterBinding.ensureInitialized();
runApp(新的MyApp());
