The plugin relies on Flutter's new mechanism for embedding Android and iOS views. As that mechanism is currently in a developers preview, this plugin should also be considered a developers preview.

To use this plugin on iOS you need to opt-in for the embedded views preview by adding a boolean property to the app's Info. Keyboard support within webviews is experimental. The Android version relies on some low-level knobs that have not been well tested on a broad spectrum of devices yet, and therefore it is not recommended to rely on webview keyboard in production apps yet.

See the webview-keyboard for known issues with keyboard input. Opt-in to the embedded views preview by adding a boolean property to the app's Info. 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. Alternatively, your editor might support flutter pub get.

Synchronous NavigationDelegates should still continue to function without any change in behavior. This correctly sets the minimum SDK to the latest stable and avoid any compile errors. This shouldn't affect existing functionality. Plugin authors who use the V2 embedding can now register the plugin and expect that it correctly responds to app lifecycle changes. This basic support currently only works with Flutter master. The keyboard will still appear when it previously did not when run with older versions of Flutter.

But if the WebView is resized while showing the keyboard the text field will need to be focused multiple times for any input to be registered. Bump minimum Flutter version to 1.Home New Browse Search [? Note You need to log in before you can comment on or make changes to this bug.

Attachments Add an attachment proposed patch, testcase, etc. Steps to Reproduce: 1. Create a WKWebView and load a request. Version: iOS 8.Many web pages provide a form where users can upload photos, videos and other files, like for example on the photo community flickr.

The button to select the file is disabled and not working.

How to intercept the request that an WebView does on all platforms?

I found this situation not very satisfying. So I tried to find a way to add support for file uploads in iCab Mobile, and had some success. Note: With the upcoming iOS 6 release later this year, the web engine of the iOS will also add support for file uploads, though only for photos or videos. This blog post will explain how iCab Mobile implements the file upload support, lists all the limitations resulting from this implementation and which are caused by the iOS itself.

This post will also give web authors all the information they need to make sure that file upload forms on their web pages do work with iCab Mobile and what they can do to make the user experience even better. When submitting the form, the browser would include the data of the file into the HTTP request and post it to the server. In the web engine of the iOS there are several things which do not work. In HTML these are defined this way:. This additional input element is required to store the information about the selected file in the form.

When the form is submitted, it is impossible to directly add the file data that needs to be uploaded to HTTP request that is sent to the server. The web engine does not support file uploads and therefore is not prepared to process any files and their data. So what iCab Mobile needs to do is to intercept the HTTP request which the web engine is building when submitting the form and to modify the request by adding the file data somehow. Only when this is the case, this request could be a file upload and iCab Mobile needs to do something more.

This modified request is then send to the server. The server gets the same request from iCab Mobile it would have received from a desktop browser which built-in file upload support.

The page can only update itself when the upload is finished. This is not very user-friendly, especially when uploading larger files, like videos, where the web page can be blocked for a long time this is not an issue of iCab Mobile or the iOS platform, this is a general issue of pure HTML forms and affects all browsers on all platforms in the same way.

Therefore many web pages try to improve the user experience for file uploads. The upload process itself is still blocked until it is finished, but it is moved to something that is invisible on the page like an iframe or which can run independently in the background AJAXso as long as the user does not leave the page, the upload can be done without blocking the interaction with the main page.

Also many web pages try to check if the form is filled out properly before it submits the form data to the server. This helps to avoid resubmitting forms because certain fields were filled out out wrong.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Hi, we're working on a small RN project which has an in-app browser embed inside, the product itself has been released on AppStore, but yet we have received some randomly error screen rendered in the WebView, after a long time investigation, we finally figured out it's the iOS deep linking URL scheme triggered the default WebView error render view, which can be easily reproduced via entering a SlideShare.

If we open the test link mentioned above in Safari. I've been searched the issues reported here, found these issue might be related to this error:, The question which I don't know the answer to is whether this behavior is inherent to WebView and the right solution is switching to WKWebView as some have suggestedor whether this can just be fixed in WebView.

Alternatively, could add a property to WebView supporting an array of ignored protocols. For a quick and dirty solution until this is resolved I modified the above linked line as such to support Plaid Link:.

I'm on RN version 0. In the code above, if we found the URL is not whatever we can handle, we skip it to avoid any error message being throw to React Native, and asks iOS if user's device is capable to handle that custom scheme url, if so, we hand over the URL to iOS so user still get other apps' deep linking URL working.

Hi there! This issue is being closed because it has been inactive for a while. Maybe the issue has been fixed in a recent release, or perhaps it is not affecting a lot of people. Either way, we're automatically closing issues after a period of inactivity.

Please do not take it personally! If you think this issue should definitely remain open, please let us know. The following information is helpful when it comes to determining if the issue should be re-opened:. If you would like to work on a patch to fix the issue, contributions are very welcome!

Every Xamarin. Forms view has an accompanying renderer for each platform that creates an instance of a native control. When a WebView is rendered by a Xamarin. For more information about the renderer and native control classes that Xamarin. The following diagram illustrates the relationship between the View and the corresponding native controls that implement it:.

The rendering process can be used to implement platform customizations by creating a custom renderer for a WebView on each platform. The process for doing this is as follows:. Each item will now be discussed in turn to implement a HybridWebView renderer that enhances the Xamarin.

For more information, see Invoking JavaScript. The HybridWebView custom control is created in the. NET Standard library project by declaring a namespace for its location and using the namespace prefix on the custom control. The local namespace prefix can be named anything.

However, the clr-namespace and assembly values must match the details of the custom control. Once the namespace is declared, the prefix is used to reference the custom control. The following code example shows how the HybridWebView custom control can be consumed by a C page:. The HybridWebView instance will be used to display a native web control on each platform. It's Uri property is set to an HTML file that is stored in each platform project, and which will be displayed by the native web control.

A custom renderer can now be added to each application project to enhance the platform web controls by allowing C code to be invoked from JavaScript. For most Xamarin.In this blog, we will go through proxying an iOS application which uses native web sockets to interact with a web server.

The blog will help penetration testers who are trying to intercept sensitive data that is being sent by an iOS application in a non-trivial manner over the network because some applications do not respect the iOS proxy settings. During a recent iOS application penetration test, I encountered an iOS application that was sending data to port 20xx on a web server. One of the reasons that the normal proxying method might be failing is because it might be using some native websockets to interact with the web server instead of the normal UIWebView class.

For more technical details of how websockets in native iOS can be configured, check out this elabs blog post.

There is a workaround to fix this problem. The blog is divided into three main steps.

Start the Metasploit console to perform DNS spoofing and enter the following commands.For other redirections the delegate methods is called as expected. This iOS bug introduces some issues because the components which have initiated the request like an instance of UIWebView does not get notified about the redirection and assumes that the URL scheme is still "http".

So even if the real URL of the site is a secure one, the web page still assumes an unsecure one. The Javascript property "location. Is there a worksround available for this? Am I doing something wrong? But I'm not sure if this has some negative side effects, especially because I'm not yet sure if I've found all circumstances under which this bug within NSURLSession occurs and what exactly UIWebView is doing when it receives a redirection notification.

This delegate callback:. But the problem remains. After the request, the following delegate methods are called in this order:. In this case the following delegate methods are called in this order:. This all happens under iOS BTW: under iOS 9. So this seems to be a bug of iOS I haven't checked in I tried again to reproduce the problem with DuckDuckGo without any success.

In Xcode 8. These two factoids site-specific behaviour, never hitting the wire got me thinking about HSTS. And some quick spelunking in the debugger reveals that this is, indeed, the culprit.

However, in your case UIWebView is the main client, and that complicates things. Regardless of what else you do, you should file a bug about this oddity.

In fact, it may make sense to file a suite of bugs, including:. Of course I can not pass the "original" redirection response and requests here, because I do not have them, but I can create a "fake" one which includes at least all the values that are needed, borrow them from the response and request which I do have. And it seems to work fine so far.
