I'm looking for a way to get the actual Flutter Webview User Agent before loading an url.
It seems not be possible...
Hey :) I'm a little late, but to answer your question, yes this is defintely possible and here's how I've done it in the past:
After you've set your web view controller, e.g.:
import 'package:webview_flutter/webview_flutter.dart';
....
late WebViewController webViewControllerObj;
....
webViewControllerObj = WebViewController.fromPlatformCreationParams(paramsObj);
if (webViewControllerObj.platform is WebKitWebViewController) {
(webViewControllerObj.platform as WebKitWebViewController).setInspectable(true);
}
webViewControllerObj
..setJavaScriptMode(JavaScriptMode.unrestricted)
..addJavaScriptChannel('Flutter', onMessageReceived: handleWebMessage)
..setNavigationDelegate(NavigationDelegate(
........
You can retrieve the userAgent string before loading the url like so:
var userAgentStr = await webViewControllerObj.getUserAgent();
Hope this helps, let me know if you have any questions - Amy :)
