useShouldOverrideUrlLoading is broken for InAppWebView

[peter-meemo]

On ios: the provided shouldOverrideUrlLoading callback is never called.
On android: the browser sometimes returns empty pages.

[YudiH]

Any solutions for this? Having the same issue when I put useShouldOverrideUrlLoading": true in initialOptions. Empty/blank page. Loads fine when I remove that option.

I'm trying to find a solution to listen to url changes. Is there a workaround for this plugin? Or is the alternative only in finding/using some other plugin?

Cheers

[YudiH]

For now, my bandage solution is listening to the url change inside onLoadStart, seems to fire everytime a diff url has to load.

[pcg92]

@YudiH im using onLoadStart on ios and seems not working, only the first time, Can you show me your code please?

[YudiH]

@pcegarra

That's all I did. Made a function that takes the loaded url and do with it whatever you need.
You could add a print() to check whenever it fires. Should help you understand how it works on ios. I personally am testing this on Android. So I can't help you there, sorry. Hope this helps.

Try the latest version of the plugin. Also, this plugin changed its name to flutter_inappwebview. The current latest version now is 2.1.0+1. So, you can change your dependency influtter_inappwebview: ^2.1.0+1.

@pichillilorenzo
I can confirm this issue still happen on iOS with the latest version in my pubspec.yaml: flutter_inappwebview: ^2.1.0+1
Here is my code:

InAppWebView(
          initialUrl: "https://www.google.com",
          initialOptions: InAppWebViewWidgetOptions(inAppWebViewOptions: InAppWebViewOptions(useShouldOverrideUrlLoading: true, useOnLoadResource: true)),
          onLoadStop: (InAppWebViewController controller, String url) {
            hideLoading();
          }, shouldOverrideUrlLoading: (InAppWebViewController controller, String url) {
              LogUtil.v("shouldOverrideUrlLoading $url");
          })

The shouldOverrideUrlLoading callback is never called

[pichillilorenzo]

@ductranit Do you mean at the first load or also when you navigate other links?

In the first load, the shouldOverrideUrlLoading event is not called (that's because both Android and iOS platforms don't call this event in their webview implementation).

[ductranit]

@pichillilorenzo ok, so it isn't called on the first time.
When user clicks on an url, it works
But when website is navigated by javascript, shouldOverrideUrlLoading isn't called.
For example, my app uses azure b2c authenticate, after user login, it redirects to https://jwt.ms to get the token, only the onLoadStop works (but I need to handle url before it loads). I tried the plugin https://pub.dev/packages/webview_flutter
and it can catch all the navigations in the navigationDelegate callback.

[pichillilorenzo]

@ductranit then you can try the onNavigationStateChange event. As the documentation says:

Event fired when the navigation state of the InAppWebView changes throught the usage of javascript History API functions (pushState(), replaceState()) and onpopstate event.

Also, the event is fired when the javascript window.location changes without reloading the webview (for example appending or modifying an hash to the url).

Let me know

[ductranit]

@pichillilorenzo the onNavigationStateChange is never called. I debug & see these events are called when it navigates:

• onLoadStop: when the url is loaded completely
• onProgressChanged: I use controller.getUrl() during the progress changed, but this way isn't stable, sometime the url changes after progress is 100 (page loaded)
• onLoadResource - same as onProgressChanged (page loaded)

[YudiH]

Try the latest version of the plugin. Also, this plugin changed its name to flutter_inappwebview. The current latest version now is 2.1.0+1. So, you can change your dependency influtter_inappwebview: ^2.1.0+1.

@pichillilorenzo Updated to that version. But a friend that built on ios reported this problem:

CustomeSchemeHandler.swift:22:27: warning:
expression implicitly coerced from 'String?' to 'Any'
print((result as! FlutterError).message

Had to revert back to flutter_inappbrowser 1.2.2 for now

I have the same issue with federated sign in through Cognito, switching over to https://pub.dev/packages/webview_flutter

[arnaudelub]

i'm facing the same issue, i'm using the git url in my pubsec.yaml:

flutter_inappwebview:
  git: 
    url: https://github.com/pichillilorenzo/flutter_inappwebview

It's working fine in debug mode, but in release, the souldOverrideUrlLoading is never triggered on Android. On iOS, it's working fine

Update

Using controller.getOptions() i can see that, while in debug, options are set correctly but in release mode, every option is equal to null

Update 2

Found out that shouldOverrideUrlLoading is working correctly unless using in app/build.gradle:

buildTypes{
  release {
    minifyEnabled True
  }
}

So in the meanwhile, set it to false if anyone is having the same problem as me

[pichillilorenzo]

It should work with the new version! Let me know

[dwiprawira]

Hi I think useShouldOverrideUrlLoading broken again after I updated flutter to stable version 1.22.0.

My workaround is use onLoadStart for android platform and shouldOverrideUrlLoading on iOS

[lo-re-co]

It's broken again

[mozaa-vn]

It's broken again

I'm using version 5.3.2 and it works perfectly

[Zamaruu]

I'm using version 5.3.2 and it works perfectly

Can you share your code please?

[aamir-nazir]

I'm using version 5.3.2 and it works perfectly

Can you share your code please?

I managed to get it working. I was missing something. Thank you for the quick reply.

[mozaa-vn]

I'm using version 5.3.2 and it works perfectly

Can you share your code please?

I just follow the document, here is my code:

shouldOverrideUrlLoading: (controller, navigationAction) async {
  final uri = navigationAction.request.url!;
  print("uri = " + uri.toString());
  if (uri.toString().contains(GameRoute.GAME_COMPLETE)) {
    //
    return NavigationActionPolicy.CANCEL;
  }
  return NavigationActionPolicy.ALLOW;
},

[mrgulshanyadav]

It's not working for me too in iOS.

[djks74]

Its broken.

why there is none perfect webview plugin in this world? :-(

[SCaptainCAP]

Why is this issue closed? It does not work for now

[kouchi32]

I solved the problem with this code.

InAppWebView(
  initialOptions: InAppWebViewGroupOptions(
    crossPlatform:
        InAppWebViewOptions(useShouldOverrideUrlLoading: true),
  ),
  shouldOverrideUrlLoading: (controller, navigationAction) async {
    // any code;
    return NavigationActionPolicy.ALLOW;
  },
)

[dwikurniantom]

[ghost]

@kouchi32 : This only works when you are openning any new page. If you come back, it doesn't work
