You can try my plugin flutter_inappwebview, which is a Flutter plugin that allows you to add inline WebViews or open an in-app browser window and has a lot of events, methods, and options to control WebViews.
To load an <iframe> in a WebView, you can load directly an HTML source using the initialData parameter of the InAppWebView widget or load an HTML file from the assets folder (see more here) using the initialFile parameter.
Full example using the initialData parameter and your youtube link:
import 'dart:async';
import 'package:flutter/material.dart';
import 'package:flutter_inappwebview/flutter_inappwebview.dart';
Future main() async {
runApp(new MyApp());
}
class MyApp extends StatefulWidget {
@override
_MyAppState createState() => new _MyAppState();
}
class _MyAppState extends State<MyApp> {
@override
void initState() {
super.initState();
}
@override
void dispose() {
super.dispose();
}
@override
Widget build(BuildContext context) {
return MaterialApp(
home: InAppWebViewPage()
);
}
}
class InAppWebViewPage extends StatefulWidget {
@override
_InAppWebViewPageState createState() => new _InAppWebViewPageState();
}
class _InAppWebViewPageState extends State<InAppWebViewPage> {
InAppWebViewController webView;
String iframeUrl = "https://www.youtube.com/embed/vlkNcHDFnGA";
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("InAppWebView")
),
body: Container(
child: Column(children: <Widget>[
Expanded(
child: Container(
child: InAppWebView(
initialData: InAppWebViewInitialData(
data: """

initialHeaders: {},
