Please why when I click the refresh button I will be getting _webViewController has not been initialized. On console.
My code
import 'package:flutter/material.dart';
import 'package:flutter_inappwebview/flutter_inappwebview.dart';
void main() {
WidgetsFlutterBinding.ensureInitialized();
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
late InAppWebViewController _webViewController;
late InAppWebView _webView;
bool _webViewVisible = false;
@override
void initState() {
super.initState();
_webView = _buildWebView();
}
InAppWebView _buildWebView() {
return InAppWebView(
initialUrlRequest: URLRequest(url: Uri.parse("https://example.com")),
onWebViewCreated: (controller) {
print("WebView created");
_webViewController = controller;
},
);
}
void updateWebView() {
_webViewController.loadUrl(urlRequest: URLRequest(url: Uri.parse("https://example.com/new-url")));
setState(() {
_webViewVisible = true;
});
}
@override
Widget build(BuildContext context) {
print("Building widget tree");
return Scaffold(
appBar: AppBar(
title: Text('InAppWebView Example'),
),
body: _webViewVisible ? _webView : Container(), // Conditionally show the InAppWebView
floatingActionButton: FloatingActionButton(
onPressed: () {
// Trigger the updateWebView method
updateWebView();
},
child: Icon(Icons.refresh),
),
);
}
}
