status bar overlapping my WebView screen, how to fix this? - flutter

I am building APK for my web app but the upper part of the web app is overlapped by the status bar
I want to show the status bar but not overlap my Webview, Webview must use screen size except status bar
check screenshot of the problem
import 'package:flutter/material.dart';
import 'package:webview_flutter/webview_flutter.dart';
void main() {
runApp(const myapp());
}
// ignore: camel_case_types
class myapp extends StatelessWidget {
const myapp({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
title: "Sample App",
theme: ThemeData(
primarySwatch: Colors.red,
),
home: const Scaffold(
appBar: null ,
body: WebView(
initialUrl: 'https://primexop.com/motap/appw1/index.php?app_v=1.001010&ow_id=101',
javascriptMode: JavascriptMode.unrestricted,
)),
);
}
}

wrap your Scaffold or WebView with SafeArea Widget
check the code below which fixes this issue
import 'package:flutter/material.dart';
import 'package:webview_flutter/webview_flutter.dart';
void main() {
runApp(const myapp());
}
// ignore: camel_case_types
class myapp extends StatelessWidget {
const myapp({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
title: "Sample App",
theme: ThemeData(
primarySwatch: Colors.red,
),
home: const SafeArea(
child: Scaffold(
appBar: null,
body: WebView(
javascriptMode: JavascriptMode.unrestricted,
initialUrl: "https://primexop.com/motap/appw1/index.php?app_v=1.001010&ow_id=101",
)),
),
);
}
}
I used SafeArea to wrap the Scaffold

Flutter Webview : Alternate screen for inital url not loaded

I need an alternate screen when my webpage not loaded;
Note: Webpage was hosting on localhost, so internet connectivity based changeover not possible.
Query: Can we ping IP and change over the screens
Any Possible ways to achieve this ?
** main.dart **
import 'package:flutter/material.dart';
import 'package:webview_flutter/webview_flutter.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'flutter webview',
home: Scaffold(
appBar: AppBar(

),
body: WebView(
initialUrl: "http://192.168.29.8/public/_weblogin.html",
javascriptMode: JavascriptMode.unrestricted)),
);
}
}
You can view alternative designs on onWebResourceError

Setting theme data for flutter app seems broken

I've tried everything I can think of to change the background color of my flutter app, but every time I run the app, the background is black.
This is main.dart
import 'package:firebase_core/firebase_core.dart';
import 'package:flutter/material.dart';
import 'package:get/get.dart';
import 'auth_controller.dart';
import 'themes/color.dart';
import 'index.dart';
Future<void> main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp().then((value) => Get.put(AuthController));
runApp(MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
// This widget is the root of your application.
#override
Widget build(BuildContext context) {
return MaterialApp(
//ThemeData
title: 'Title',
theme: ThemeData(
brightness: Brightness.light,
),
home:const Index(),
debugShowCheckedModeBanner: false,
);
}
}
I don't think I'm even using themes/color.dart but I thought I'd leave it in anyway. Brightness should set it.
This is index.dart
import 'package:flutter/material.dart';
import 'themes/color.dart';
import 'signup.dart';
Future<void> main() async {
runApp(MyApp(
routes: <String, WidgetBuilder>{
'/signup': (BuildContext context) => const SignUp()
},
debugShowCheckedModeBanner: false,
));
}
class MyApp extends StatelessWidget {
const MyApp({Key? key, required Map<String, WidgetBuilder> routes, required bool debugShowCheckedModeBanner}) : super(key: key);
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Welcome to Flutter',
home: Scaffold(
backgroundColor: const Color(0xFFe3e4e4),
appBar: AppBar(
title: const Text('Flutter Screen Background Color Example'),
),
body: const Center(child: Index()),
),
);
}
}
class Index extends StatelessWidget {
const Index({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
return Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
const SizedBox(height: 20,),
ElevatedButton(
child: const Text('WTF'),
onPressed: () {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => const SignUp()),
);
}
),
]
)
);
}
}
It seems like the background should be a light grey,but it's black. I tried invalidating the caches and restarting too.

How to get rid of address bar and bottom bar in Flutter 'WebBrowser' Plugin?

My App is a Flutter WEB app.
This is the plugin I am using to display some HTML coming from the server:
https://pub.dev/packages/web_browser
Here is the code I am using:
WebBrowser(
initialUrl: 'https://${Provider.of<CP>(context).getPaymentURL()+Provider.of<CP>(context).getPaymentPATH()}?O=${Provider.of<CP>(context).getOrder().orderUID}&Ro=${Provider.of<CP>(context).getOrder().res_key}',
),
My screen looks like below:
I would like to rid of the address bar and bottom bar but not sure how. Can someone help please?
You can copy paste run full code below
You can use attribute interactionSettings and set WebBrowserInteractionSettings's topBar and bottomBar to SizedBox.shrink()
code snippet
return WebBrowser(
initialUrl: 'https://dart.dev/',
interactionSettings: WebBrowserInteractionSettings(
topBar: SizedBox.shrink(), bottomBar: SizedBox.shrink()));

Flutter / webview_flutter too big to fit screen

I am running flutter 1.17.1, using webview_flutter: ^0.3.21
dependencies added to pubspec.yaml and added this to the end of info.plist
<key>io.flutter.embedded_views_preview</key>
<string>YES</string>
Problem: Webpage loaded into webview is too big to fit mobile phone screen.
screenshot
Here is the code with the webview:
import 'package:flutter/material.dart';
import 'package:webview_flutter/webview_flutter.dart';
class WebViewContainer extends StatefulWidget {
final url;
WebViewContainer(this.url);
#override
createState() => _WebViewContainerState(this.url);
}
class _WebViewContainerState extends State<WebViewContainer> {
var _url;
final _key = UniqueKey();
_WebViewContainerState(this._url);
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(),
body: Column(
children: [
Expanded(
child: WebView(
key: _key,
javascriptMode: JavascriptMode.unrestricted,
initialUrl: _url))
],
));
}
}

I've tried a minimal repro with the url "https://www.businessinsider.jp/" and the latest version of webview_flutter, this is the output:
Minimal repro:
import 'package:flutter/material.dart';
import 'package:webview_flutter/webview_flutter.dart';
import 'dart:async';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
visualDensity: VisualDensity.adaptivePlatformDensity,
),
home: MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key? key, required this.title}) : super(key: key);
final String title;
#override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
final Completer<WebViewController> _controller =
Completer<WebViewController>();
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: WebView(
initialUrl: "https://www.businessinsider.jp/",
onWebViewCreated: (WebViewController webViewController) {
_controller.complete(webViewController);
},
javascriptMode: JavascriptMode.unrestricted,
),
);
}
}
It seems that the issue doesn't occur in the latest version.
Use InAppWebView instead of WebView.
This will add a line like this to your package's pubspec.yaml:
dependencies:
flutter_inappwebview: ^5.3.2
Here is a code example:
return InAppWebView(
initialOptions: InAppWebViewGroupOptions(
android: AndroidInAppWebViewOptions(
useHybridComposition: true,
textZoom: 100 * 2 // it makes 2 times bigger
)
),
onWebViewCreated: (InAppWebViewController controller) {
webViewController = controller;
controller.loadData(data: widget.html, mimeType: "text/html");
},
);
If you want to make it smaller, you just need to divide it as below:
textZoom: 100 / 2 // it makes 2 times smaller
