Running the code given as example:
import 'package:flutter/material.dart';
import 'package:flutter_inappbrowser/flutter_inappbrowser.dart';
class MyInAppBrowser extends InAppBrowser {
@override
Future onLoadStart(String url) async {
print("\n\nStarted $url\n\n");
}
@override
Future onLoadStop(String url) async {
print("\n\nStopped $url\n\n");
}
@override
void onLoadError(String url, int code, String message) {
print("\n\nCan't load $url.. Error: $message\n\n");
}
@override
void onExit() {
print("\n\nBrowser closed!\n\n");
}
}
MyInAppBrowser inAppBrowserFallback = new MyInAppBrowser();
class MyChromeSafariBrowser extends ChromeSafariBrowser {
MyChromeSafariBrowser(browserFallback) : super(browserFallback);
@override
void onOpened() {
print("ChromeSafari browser opened");
}
@override
void onLoaded() {
print("ChromeSafari browser loaded");
}
@override
void onClosed() {
print("ChromeSafari browser closed");
}
}
MyChromeSafariBrowser chromeSafariBrowser = new MyChromeSafariBrowser(inAppBrowserFallback);
void main() => runApp(new MyApp());
class MyApp extends StatefulWidget {
@override
_MyAppState createState() => new _MyAppState();
}
class _MyAppState extends State<MyApp> {
@override
void initState() {
super.initState();
}
@override
Widget build(BuildContext context) {
return new MaterialApp(
home: new Scaffold(
appBar: new AppBar(
title: const Text('Flutter InAppBrowser Plugin example app'),
),
body: new Center(
child: new RaisedButton(onPressed: () {
chromeSafariBrowser.open("https://flutter.io/", options: {
"addShareButton": false,
"toolbarBackgroundColor": "#000000",
"dismissButtonStyle": 1,
"preferredBarTintColor": "#000000",
},
optionsFallback: {
"toolbarTopBackgroundColor": "#000000",
"closeButtonCaption": "Close"
});
},
child: Text("Open ChromeSafariBrowser")
