Smart flutter WebView App -Web To App – Android and ios Web View – Multi URL Support

Introduction

The Smart Flutter WebView App is a powerful and customizable web view plugin for Flutter that allows you to integrate web content into your mobile app. With this plugin, you can load multiple URLs, handle navigation, and even add custom headers and user agents. In this tutorial, we will cover the basics of using the Smart Flutter WebView App and show you how to get started with adding web content to your Flutter app.

Step 1: Adding the Plugin to Your Project

To use the Smart Flutter WebView App, you need to add the plugin to your Flutter project. Here's how:

1. Open your Flutter project in Android Studio or your preferred IDE.
2. Open the pubspec.yaml file and add the following line under the dependencies section:

   dependencies:
   smart_webview: ^2.0.0

3. Save the pubspec.yaml file and run flutter pub get to install the plugin.

Step 2: Importing the Plugin

Once the plugin is installed, you need to import it in your Dart file. Here's how:

1. Open the Dart file where you want to use the web view.
2. Add the following line at the top of the file:

   import 'package:smart_webview/smart_webview.dart';

   Step 3: Creating a Web View

Now that you have imported the plugin, you can create a web view widget. Here's how:

1. Create a new stateless widget:

   class MyWebView extends StatelessWidget {
   @override
   Widget build(BuildContext context) {
   return SmartWebView(
     url: 'https://www.example.com',
     onNavigationRequest: (request) {
       print('Navigation request: ${request.url}');
       return true;
     },
   );
   }
   }

   In this example, we are creating a SmartWebView widget and passing in the URL 'https://www.example.com' as a parameter. We are also defining a callback function onNavigationRequest that will be called whenever the user navigates to a new URL.

Step 4: Customizing the Web View

The SmartWebView widget has several properties that you can customize to fit your needs. Here are a few examples:

• url: The URL to load initially.
• onNavigationRequest: A callback function that will be called whenever the user navigates to a new URL.
• headers: A map of headers to send with the request.
• userAgent: The user agent to use for the request.

Here's an example of how you can customize the web view:

class MyWebView extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return SmartWebView(
      url: 'https://www.example.com',
      onNavigationRequest: (request) {
        print('Navigation request: ${request.url}');
        return true;
      },
      headers: {
        'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
        'Accept-Language': 'en-US,en;q=0.5',
      },
      userAgent: 'Mozilla/5.0 (iPhone; CPU iPhone OS 12_1_4 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/12.0 Mobile/15E148 Safari/604.1',
    );
  }
}

In this example, we are setting the headers property to a map of headers and the userAgent property to a custom user agent string.

Step 5: Using the Web View

Once you have created the web view widget, you can use it in your app. Here's an example of how you can use the web view in a MaterialApp:

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'My App',
      home: Scaffold(
        appBar: AppBar(
          title: Text('My App'),
        ),
        body: Center(
          child: MyWebView(),
        ),
      ),
    );
  }
}

In this example, we are creating a MaterialApp and setting the home property to a Scaffold that contains a Center widget with our MyWebView widget.

Step 6: Handling Multiple URLs

The SmartWebView widget can handle multiple URLs. Here's an example of how you can load multiple URLs:

class MyWebView extends StatefulWidget {
  @override
  _MyWebViewState createState() => _MyWebViewState();
}

class _MyWebViewState extends State<MyWebView> {
  SmartWebViewController _controller;

  @override
  void initState() {
    super.initState();
    _controller = SmartWebViewController();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('My App'),
      ),
      body: Center(
        child: SmartWebView(
          controller: _controller,
          urls: [
            'https://www.example.com',
            'https://www.example.net',
            'https://www.example.io',
          ],
        ),
      ),
    );
  }
}

In this example, we are creating a SmartWebView widget and passing in a list of URLs using the urls property. We are also defining a SmartWebViewController to manage the web view.

Conclusion

In this tutorial, we have covered the basics of using the Smart Flutter WebView App to integrate web content into your Flutter app. We have shown you how to create a web view widget, customize the web view, and handle multiple URLs. With this plugin, you can create a powerful and customizable web view that can be used in a variety of apps.
