To enable downloads in a Flutter WebView, you need to follow these steps:
webview_flutter
package to your project. You can do this by adding the following line to your pubspec.yaml
file:dependencies:
webview_flutter: ^2.0.10
import 'package:webview_flutter/webview_flutter.dart';
javascriptMode
property to JavascriptMode.unrestricted
to enable JavaScript:WebView(
initialUrl: 'https://example.com',
javascriptMode: JavascriptMode.unrestricted,
),
NavigationDelegate
to the WebView to handle download requests:WebView(
initialUrl: 'https://example.com',
javascriptMode: JavascriptMode.unrestricted,
navigationDelegate: (NavigationRequest request) {
if (request.url.endsWith('.pdf')) {
// Handle PDF download
// You can open the PDF using a PDF viewer or save it to the local device
return NavigationDecision.prevent;
} else {
// Allow all other navigation requests
return NavigationDecision.navigate;
}
},
),
In the navigationDelegate
function, you can check if the requested URL is a download link (e.g. it ends with .pdf
, .doc
, or other file extensions). You can then handle the download using any method you want, such as opening the file in a third-party app or saving it to the local device.
Note that some websites may use special download links or JavaScript functions to initiate downloads, so you may need to use a more complex approach to detect and handle these cases.
