talkjs_webview_flutter 3.0.7

A Flutter plugin that provides a WebView widget on Android and iOS.

WebView for TalkJS Flutter SDK

A Flutter plugin that provides a WebView widget.

IMPORTANT

This is a fork that depends on talkjs_webview_flutter_android. which provides file upload support to the Android implementation of the WebView. It also depends on talkjs_webview_flutter_wkwebview. The changes made are specific to the TalkJS Flutter SDK and hence this package is NOT intended for use with other packages/plugins.

On iOS the WebView widget is backed by a WKWebView; On Android the WebView widget is backed by a WebView.

	Android	iOS
Support	SDK 19+ or 20+	9.0+

Usage

Add talkjs_webview_flutter as a dependency in your pubspec.yaml file. If you are targeting Android, make sure to read the Android Platform Views section below to choose the platform view mode that best suits your needs.

You can now include a WebView widget in your widget tree. See the WebView widget's Dartdoc for more details on how to use the widget.

Android Platform Views

This plugin uses Platform Views to embed the Android’s webview within the Flutter app. It supports two modes: hybrid composition (the current default) and virtual display.

Here are some points to consider when choosing between the two:

• Hybrid composition has built-in keyboard support while virtual display has multiple keyboard issues.
• Hybrid composition requires Android SDK 19+ while virtual display requires Android SDK 20+.
• Hybrid composition and virtual display have different performance tradeoffs.

Using Hybrid Composition

The mode is currently enabled by default. You should however make sure to set the correct minSdkVersion in android/app/build.gradle if it was previously lower than 19:

android {
    defaultConfig {
        minSdkVersion 19
    }
}

Using Virtual displays

1. Set the correct minSdkVersion in android/app/build.gradle (if it was previously lower than 20):

   android {
       defaultConfig {
           minSdkVersion 20
       }
   }
   

2. Set WebView.platform = AndroidWebView(); in initState(). For example:

   import 'dart:io';
   
   import 'package:talkjs_webview_flutter/webview_flutter.dart';
   
   class WebViewExample extends StatefulWidget {
     @override
     WebViewExampleState createState() => WebViewExampleState();
   }
   
   class WebViewExampleState extends State<WebViewExample> {
     @override
     void initState() {
       super.initState();
       // Enable virtual display.
       if (Platform.isAndroid) WebView.platform = AndroidWebView();
     }
   
     @override
     Widget build(BuildContext context) {
       return WebView(
         initialUrl: 'https://flutter.dev',
       );
     }
   }
   

Enable Material Components for Android

To use Material Components when the user interacts with input elements in the WebView, follow the steps described in the Enabling Material Components instructions.

Setting custom headers on POST requests

Currently, setting custom headers when making a post request with the WebViewController's loadRequest method is not supported on Android. If you require this functionality, a workaround is to make the request manually, and then load the response data using loadHTMLString instead.
