This example shows how to integrate the Tiledesk Widget via a WebView for Flutter.
This guide will use the package to implement a Webview, but other similar packages should work with minimal changes to the code.
import 'dart:async';
import 'package:flutter/material.dart';
import 'package:webview_flutter/webview_flutter.dart';
import 'package:webview_flutter_android/webview_flutter_android.dart';
import 'package:webview_flutter_wkwebview/webview_flutter_wkwebview.dart';
class Webview extends StatefulWidget {
const WebView();
@override
ConsumerState<WebView> createState() => _WebViewState();
}
class _WebViewState extends State<WebView> {
late final _controller = WebViewController();
@override
void initState() {
super.initState();
unawaited(_initializeController());
}
@override
Widget build(BuildContext context) {
return ColoredBox(
color: Colors.white,
child: WebViewWidget(controller: _controller),
);
}
Future<void> _initializeController() async {
// disable javascript dialog
await _controller.setOnJavaScriptAlertDialog((request) async {
return;
});
switch (_controller.platform) {
case final AndroidWebViewController controller:
await controller.setOnShowFileSelector((params) {
// implement your logic to show a file picker
// attachment upload will not work on android unless this is setup
});
case final WebKitWebViewController _:
break;
}
await _controller.setJavaScriptMode(JavaScriptMode.unrestricted);
return _loadRequest();
}
Future<void> _loadRequest() async {
final navigationDelegate = NavigationDelegate(
onPageFinished: (url) {
// this is necessary to trigger the widget to show without the need for
//the user to interact with the webview
_controller.runJavaScript('''
document.dispatchEvent(new Event('mousemove'));
''');
}
onNavigationRequest: (request) {
// intercept url navigation
// this may be useful to display attachments like PDFs in a custom widget
// if(request.url.endsWith('.pdf')) {
// Navigator.of(context).push(MyPdfViewer());
// return NavigationDecision.prevent;
// }
return NavigationDecision.navigate;
},
);
await _controller.setNavigationDelegate(navigationDelegate);
return _controller.loadHtmlString(
