java.lang.IllegalStateException:尝试创建未注册类型的平台视图: com.pichillilorenzo/flutter_inappwebview

我使用这个库来显示一个经过解析的epub文件，它支持显示.css。flutter_inappwebview。
var doc = state.book.Chapters.last.HtmlContent.split('<head>');
var styledTML = "\n" +
doc.first +
"\n" +
"<head>" +
"<style>" +
state.book.Content.Css['styles.css'].Content +
"</style>" +
doc.last;
return Material(
child: InAppWebView(
onWebViewCreated: (controller) {
controller.loadData(data: styledTML);
},
initialOptions: InAppWebViewWidgetOptions(),
),
);
}这段代码在iOS上运行得很好，但在安卓上我遇到了错误：

E/flutter ( 7880): 我试过flutter clean了。正在重新启动IDE。我的项目是AndroidX项目，我在Manifest中添加了互联网权限，我的项目比API21更多，但它仍然崩溃。我如何反映这个HTML。我很感谢你的时间和想法。谢谢
