How to open a link in a in-app browser window in flutter and how to change browser window header

I would like to know how to open links in an in-app browser, just like this:enter image description here

You can achieve this using flutter_webview plugin.
Example code:
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('Flutter WebView example'),
// This drop down menu demonstrates that Flutter widgets can be shown over the web view.
actions: <Widget>[
NavigationControls(_controller.future),
SampleMenu(_controller.future),
],
),
// We're using a Builder here so we have a context that is below the Scaffold
// to allow calling Scaffold.of(context) so we can show a snackbar.
body: Builder(builder: (BuildContext context) {
return WebView(
initialUrl: 'https://flutter.dev',
javascriptMode: JavascriptMode.unrestricted,
onWebViewCreated: (WebViewController webViewController) {
_controller.complete(webViewController);
},
onProgress: (int progress) {
print("WebView is loading (progress : $progress%)");
},
javascriptChannels: <JavascriptChannel>{
_toasterJavascriptChannel(context),
},
navigationDelegate: (NavigationRequest request) {
if (request.url.startsWith('https://www.youtube.com/')) {
print('blocking navigation to $request}');
return NavigationDecision.prevent;
}
print('allowing navigation to $request');
return NavigationDecision.navigate;
},
onPageStarted: (String url) {
print('Page started loading: $url');
},
onPageFinished: (String url) {
print('Page finished loading: $url');
},
gestureNavigationEnabled: true,
);
}),
floatingActionButton: favoriteButton(),
);
}

I'm building a flutter application, and am having some trouble actually opening the app using the firebase_dynamic_links package. I basically took the example code found at https://pub.dev/packages/firebase_dynamic_links#-example-tab- in order to get started, but changed the information in their example to match my own firebase project (which has been setup in both android and iOS, but this testing has all been done with iOS).
I will include code and more useful information below, but I was really just hoping to get a simplified example of how this process should work. I have searched online quite a bit, following different tutorials, but none of them have done the trick for me. It could just be that I'm quite new to flutter, and am missing basic things. In my final application, I will be using dynamic links to allow users to invite other users to join the app (as well as groups within the app) via text, just to give context as to why it is needed.
Here is the code for what I have so far, but as I mentioned it is largely based off of the example from the link above.

And lastly, here is the dynamic link I created within the console for testing. Although the final version of the application will create them programatically.
If anything else is needed please let me know. Any help would be greatly appreciated.

Flutter save the time to a variable when a user accessed a tab

Im new to flutter so please bear with me. So I have a simple webview app with 2 tabs
I just wanna ask if how can I save the user load time to a variable name lastloaded in time format then when the user re-enters that tab, a function will check the lastloaded variable if its greater than 1 minute and perform a refresh.
I honestly dont know what to search for this problem. Please assist. Thank you!
if you want to see an example code here:
class _CategoriesPageState extends State<CategoriesPage> {
WebViewController _myController;
final Completer<WebViewController> _controller =
Completer<WebViewController>();
#override
Widget build(BuildContext context) {
return SafeArea(
child: Scaffold(
body: WebView(
initialUrl: 'www.facebook.com',
javascriptMode: JavascriptMode.unrestricted,
onWebViewCreated: (controller) {
_controller.complete(controller);
},
onPageFinished: (controller) async {
(await _controller.future).evaluateJavascript("document.getElementsByClassName('footer-container')[0].style.display='none';");
(await _controller.future).evaluateJavascript("document.getElementById('st_notification_1').style.display='none';");
(await _controller.future).evaluateJavascript("document.getElementById('sidebar_box').style.display='none';");
},
),
floatingActionButton: FutureBuilder<WebViewController>(
future: _controller.future,
builder: (BuildContext context, AsyncSnapshot<WebViewController> controller) {
if (controller.hasData) {
return FloatingActionButton(
onPressed: () {
controller.data.reload();
},
child: Icon(Icons.refresh),
);
}
return Container();
}
),
),
);
}
}

For getting the date and time, User DateTime class. Use this class and use the function difference to get the difference between DateTimes.
var lastLoaded;
void tappingOnTab(){
final now = DateTime.now();
if(lastLoaded != null){
if(now.difference(lastLoaded).inMinutes > 1){
// yes last loaded time is more than 1 min ago
}
}
lastLoaded = now;
}
If you want to persist the last loaded time over multiple app instances, use SharedPreferences: https://pub.dev/packages/shared_preferences.

Is there WebView in Flutter? [duplicate]

Closed 2 years ago.
I am looking for WebView in flutter. How can I show my Html contents in flutter ?
Actually our books format is Html so I need WebView or a way to parse Html in flutter programming.

A Flutter plugin that provides a webview widget is available now for Developers Preview
usage
return Scaffold(
appBar: AppBar(
title: const Text('Flutter WebView example'),
),
body: const WebView(
initialUrl: 'https://flutter.io',
javaScriptMode: JavaScriptMode.unrestricted,
),
);
full code

You can use
> flutter_webview_plugin
It is a plugin that allow Flutter to communicate with a native WebView.
Note: The webview is not integrated in the widget tree, it is a native view on top of the flutter view. you won't be able to use snackbars, dialogs ...

You can use my plugin flutter_inappwebview, which is a Flutter Plugin that allows you to add inline webviews integrated with the widget tree or open an in-app browser window! It offers a lot of events, methods, and options compared to other webview plugins!
Main Classes:
InAppWebView: Flutter Widget for adding an inline native WebView integrated into the flutter widget tree. To use InAppWebView class on iOS you need to opt-in for the embedded views preview by adding a boolean property to the app's Info.plist file, with the key io.flutter.embedded_views_preview and the value YES.
ContextMenu: This class represents the WebView context menu.
HeadlessInAppWebView: Class that represents a WebView in headless mode. It can be used to run a WebView in background without attaching an InAppWebView to the widget tree.
InAppBrowser: In-App Browser using native WebView.
ChromeSafariBrowser: In-App Browser using Chrome Custom Tabs on Android / SFSafariViewController on iOS.
InAppLocalhostServer: This class allows you to create a simple server on http://localhost:[port]/. The default port value is 8080.
CookieManager: This class implements a singleton object (shared instance) which manages the cookies used by WebView instances.
HttpAuthCredentialDatabase: This class implements a singleton object (shared instance) which manages the shared HTTP auth credentials cache.
WebStorageManager: This class implements a singleton object (shared instance) which manages the web storage used by WebView instances.
Quick example:
import 'dart:async';
import 'package:flutter/material.dart';
import 'package:flutter_inappwebview/flutter_inappwebview.dart';
Future main() async {
WidgetsFlutterBinding.ensureInitialized();
runApp(new MyApp());
}
class MyApp extends StatefulWidget {
#override
_MyAppState createState() => new _MyAppState();
}
class _MyAppState extends State<MyApp> {
InAppWebViewController webView;
String url = "";
double progress = 0;
#override
void initState() {
super.initState();
}
#override
void dispose() {
super.dispose();
}
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: const Text('InAppWebView Example'),
),
body: Container(
child: Column(children: <Widget>[
Container(
padding: EdgeInsets.all(20.0),
child: Text(
"CURRENT URL\n${(url.length > 50) ? url.substring(0, 50) + "..." : url}"),
),
Container(
padding: EdgeInsets.all(10.0),
child: progress < 1.0
? LinearProgressIndicator(value: progress)
: Container()),
Expanded(
child: Container(
margin: const EdgeInsets.all(10.0),
decoration:
BoxDecoration(border: Border.all(color: Colors.blueAccent)),
child: InAppWebView(
initialUrl: "https://flutter.dev/",
initialHeaders: {},
initialOptions: InAppWebViewGroupOptions(
crossPlatform: InAppWebViewOptions(
debuggingEnabled: true,
)
),
onWebViewCreated: (InAppWebViewController controller) {
webView = controller;
},
onLoadStart: (InAppWebViewController controller, String url) {
setState(() {
this.url = url;
});
},
onLoadStop: (InAppWebViewController controller, String url) async {
setState(() {
this.url = url;
});
},
onProgressChanged: (InAppWebViewController controller, int progress) {
setState(() {
this.progress = progress / 100;
});
},
),
),
),
ButtonBar(
alignment: MainAxisAlignment.center,
children: <Widget>[
RaisedButton(
child: Icon(Icons.arrow_back),
onPressed: () {
if (webView != null) {
webView.goBack();
}
},
),
RaisedButton(
child: Icon(Icons.arrow_forward),
onPressed: () {
if (webView != null) {
webView.goForward();
}
},
),
RaisedButton(
child: Icon(Icons.refresh),
onPressed: () {
if (webView != null) {
webView.reload();
}
},
),
],
),
])),
),
);
}
}
Screenshot:

If you just want to show a static html content, you can try this package: flutter_html_view. Flutter just supports a full-screen webview, an inline webview has not been supported yet.
