• iOS WKWebView (Official API - WKUIDelegate.webView):
  • Setting these initial settings InAppWebViewSettings.supportZoom, InAppWebViewSettings.useOnLoadResource, InAppWebViewSettings.useShouldInterceptAjaxRequest, InAppWebViewSettings.useShouldInterceptFetchRequest, InAppWebViewSettings.applicationNameForUserAgent, InAppWebViewSettings.javaScriptCanOpenWindowsAutomatically, InAppWebViewSettings.javaScriptEnabled, InAppWebViewSettings.minimumFontSize, InAppWebViewSettings.preferredContentMode, InAppWebViewSettings.incognito, InAppWebViewSettings.cacheEnabled, InAppWebViewSettings.mediaPlaybackRequiresUserGesture, InAppWebViewSettings.resourceCustomSchemes, InAppWebViewSettings.sharedCookiesEnabled, InAppWebViewSettings.enableViewportScale, InAppWebViewSettings.allowsAirPlayForMediaPlayback, InAppWebViewSettings.allowsPictureInPictureMediaPlayback, InAppWebViewSettings.isFraudulentWebsiteWarningEnabled, InAppWebViewSettings.allowsInlineMediaPlayback, InAppWebViewSettings.suppressesIncrementalRendering, InAppWebViewSettings.selectionGranularity, InAppWebViewSettings.ignoresViewportScaleLimits, InAppWebViewSettings.limitsNavigationsToAppBoundDomains, InAppWebViewSettings.upgradeKnownHostsToHTTPS, will have no effect due to a WKWebView limitation when creating the new window WebView: it's impossible to return the new WKWebView with a different WKWebViewConfiguration instance (see https://developer.apple.com/documentation/webkit/wkuidelegate/1536907-webview). So, these options will be inherited from the caller WebView. Also, note that calling InAppWebViewController.setSettings method using the controller of the new created WebView, it will update also the WebView options of the caller WebView.
• macOS WKWebView (Official API - WKUIDelegate.webView):
  • Setting these initial settings InAppWebViewSettings.supportZoom, InAppWebViewSettings.useOnLoadResource, InAppWebViewSettings.useShouldInterceptAjaxRequest, InAppWebViewSettings.useShouldInterceptFetchRequest, InAppWebViewSettings.applicationNameForUserAgent, InAppWebViewSettings.javaScriptCanOpenWindowsAutomatically, InAppWebViewSettings.javaScriptEnabled, InAppWebViewSettings.minimumFontSize, InAppWebViewSettings.preferredContentMode, InAppWebViewSettings.incognito, InAppWebViewSettings.cacheEnabled, InAppWebViewSettings.mediaPlaybackRequiresUserGesture, InAppWebViewSettings.resourceCustomSchemes, InAppWebViewSettings.sharedCookiesEnabled, InAppWebViewSettings.enableViewportScale, InAppWebViewSettings.allowsAirPlayForMediaPlayback, InAppWebViewSettings.allowsPictureInPictureMediaPlayback, InAppWebViewSettings.isFraudulentWebsiteWarningEnabled, InAppWebViewSettings.allowsInlineMediaPlayback, InAppWebViewSettings.suppressesIncrementalRendering, InAppWebViewSettings.selectionGranularity, InAppWebViewSettings.ignoresViewportScaleLimits, InAppWebViewSettings.limitsNavigationsToAppBoundDomains, InAppWebViewSettings.upgradeKnownHostsToHTTPS, will have no effect due to a WKWebView limitation when creating the new window WebView: it's impossible to return the new WKWebView with a different WKWebViewConfiguration instance (see https://developer.apple.com/documentation/webkit/wkuidelegate/1536907-webview).

Officially Supported Platforms/Implementations:

• Android WebView:
  • In order to be able to listen this event, check the InAppWebViewSettings.useShouldInterceptAjaxRequest setting documentation. Also, on Android that doesn't support the WebViewFeature.DOCUMENT_START_SCRIPT, unlike iOS that has WKUserScript that can inject javascript code right after the document element is created but before any other content is loaded, in Android the javascript code used to intercept ajax requests is loaded as soon as possible so it won't be instantaneous as iOS. In that case, after the window.addEventListener("flutterInAppWebViewPlatformReady") event is dispatched, the ajax requests can be intercept for sure.
• iOS WKWebView
• macOS WKWebView

Can be used to check if the PlatformInAppBrowserEvents.shouldOverrideUrlLoading method is supported at runtime.

Officially Supported Platforms/Implementations:

• Android WebView (Official API - WebViewClient.shouldOverrideUrlLoading):
  • There isn't any way to load an URL for a frame that is not the main frame, so if the request is not for the main frame, the navigation is allowed by default. However, if you want to cancel requests for subframes, you can use the InAppWebViewSettings.regexToCancelSubFramesLoading setting to write a Regular Expression that, if the url request of a subframe matches, then the request of that subframe is canceled. Instead, the InAppWebViewSettings.regexToAllowSyncUrlLoading setting could be used to allow navigation requests synchronously. On Android Forge, HTTP/HTTPS main-frame navigations continue through WebView when this event returns NavigationActionPolicy.ALLOW, preserving the original browsing context. Returning NavigationActionPolicy.CANCEL attempts to stop that in-flight navigation; non-HTTP(S) URLs are reloaded after an ALLOW because Flutter method channels work asynchronously. Also, this event is not called for POST requests and is not called on the first page load.

• macOS WKWebView (Official API - WKNavigationDelegate.webView)
• Windows WebView2

Parameters - Officially Supported Platforms/Implementations:

• navigationAction: all platforms
