/// - __userAgent__: Set the custom WebView's user-agent.
/// - __javaScriptEnabled__: Set to `true` to enable JavaScript. The default value is `true`.
/// - __javaScriptCanOpenWindowsAutomatically__: Set to `true` to allow JavaScript open windows without user interaction. The default value is `false`.
/// - __hidden__: Set to `true` to create the browser and load the page, but not show it. The `onLoadStop` event fires when loading is complete. Omit or set to `false` (default) to have the browser open and load normally.
/// - __toolbarTop__: Set to `false` to hide the toolbar at the top of the WebView. The default value is `true`.
/// - __toolbarTopBackgroundColor__: Set the custom background color of the toolbar at the top.
/// - __hideUrlBar__: Set to `true` to hide the url bar on the toolbar at the top. The default value is `false`.

/// - __resourceCustomSchemes__: List of custom schemes that [InAppBrowser] must handle. Use the [onLoadResourceCustomScheme()] event to intercept resource requests with custom scheme.
///
/// - **Android** supports these additional options:
///
/// - __hideTitleBar__: Set to `true` if you want the title should be displayed. The default value is `false`.
/// - __closeOnCannotGoBack__: Set to `false` to not close the InAppBrowser when the user click on the back button and the WebView cannot go back to the history. The default value is `true`.
/// - __clearSessionCache__: Set to `true` to have the session cookie cache cleared before the new window is opened.
/// - __builtInZoomControls__: Set to `true` if the WebView should use its built-in zoom mechanisms. The default value is `false`.
/// - __displayZoomControls__: Set to `true` if the WebView should display on-screen zoom controls when using the built-in zoom mechanisms. The default value is `false`.

/// - __databaseEnabled__: Set to `true` if you want the database storage API is enabled. The default value is `false`.
/// - __domStorageEnabled__: Set to `true` if you want the DOM storage API is enabled. The default value is `false`.
/// - __useWideViewPort__: Set to `true` if the WebView should enable support for the "viewport" HTML meta tag or should use a wide viewport. When the value of the setting is false, the layout width is always set to the width of the WebView control in device-independent (CSS) pixels. When the value is true and the page contains the viewport meta tag, the value of the width specified in the tag is used. If the page does not contain the tag or does not provide a width, then a wide viewport will be used. The default value is `true`.
/// - __safeBrowsingEnabled__: Set to `true` if you want the Safe Browsing is enabled. Safe Browsing allows WebView to protect against malware and phishing attacks by verifying the links. The default value is `true`.
/// - __progressBar__: Set to `false` to hide the progress bar at the bottom of the toolbar at the top. The default value is `true`.
/// - __textZoom__: Set text scaling of the WebView. The default value is `100`.
/// - __mixedContentMode__: Configures the WebView's behavior when a secure origin attempts to load a resource from an insecure origin. By default, apps that target `Build.VERSION_CODES.KITKAT` or below default to `MIXED_CONTENT_ALWAYS_ALLOW`. Apps targeting `Build.VERSION_CODES.LOLLIPOP` default to `MIXED_CONTENT_NEVER_ALLOW`. The preferred and most secure mode of operation for the WebView is `MIXED_CONTENT_NEVER_ALLOW` and use of `MIXED_CONTENT_ALWAYS_ALLOW` is strongly discouraged.
///
/// - **iOS** supports these additional options:
///
/// - __disallowOverScroll__: Set to `true` to disable the bouncing of the WebView when the scrolling has reached an edge of the content. The default value is `false`.
/// - __toolbarBottom__: Set to `false` to hide the toolbar at the bottom of the WebView. The default value is `true`.
/// - __toolbarBottomBackgroundColor__: Set the custom background color of the toolbar at the bottom.
/// - __toolbarBottomTranslucent__: Set to `true` to set the toolbar at the bottom translucent. The default value is `true`.
/// - __closeButtonCaption__: Set the custom text for the close button.
/// - __closeButtonColor__: Set the custom color for the close button.
/// - __presentationStyle__: Set the custom modal presentation style when presenting the WebView. The default value is `0 //fullscreen`. See [UIModalPresentationStyle](https://developer.apple.com/documentation/uikit/uimodalpresentationstyle) for all the available styles.

/// - __suppressesIncrementalRendering__: Set to `true` if you want the WebView suppresses content rendering until it is fully loaded into memory.. The default value is `false`.
/// - __allowsAirPlayForMediaPlayback__: Set to `true` to allow AirPlay. The default value is `true`.
/// - __allowsBackForwardNavigationGestures__: Set to `true` to allow the horizontal swipe gestures trigger back-forward list navigations. The default value is `true`.

///All platforms support these options:
/// - __useShouldOverrideUrlLoading__: Set to `true` to be able to listen at the [InAppWebView.shouldOverrideUrlLoading()] event. The default value is `false`.
/// - __useOnLoadResource__: Set to `true` to be able to listen at the [InAppWebView.onLoadResource()] event. The default value is `false`.
/// - __useOnTargetBlank__: Set to `true` to be able to listen at the [InAppWebView.onTargetBlank()] event. The default value is `false`.
/// - __clearCache__: Set to `true` to have all the browser's cache cleared before the new window is opened. The default value is `false`.
/// - __userAgent___: Set the custom WebView's user-agent.
/// - __javaScriptEnabled__: Set to `true` to enable JavaScript. The default value is `true`.
/// - __javaScriptCanOpenWindowsAutomatically__: Set to `true` to allow JavaScript open windows without user interaction. The default value is `false`.
/// - __mediaPlaybackRequiresUserGesture__: Set to `true` to prevent HTML5 audio or video from autoplaying. The default value is `true`.
/// - __transparentBackground__: Set to `true` to make the background of the WebView transparent. If your app has a dark theme, this can prevent a white flash on initialization. The default value is `false`.
/// - __resourceCustomSchemes__: List of custom schemes that [InAppWebView] must handle. Use the [InAppWebView.onLoadResourceCustomScheme()] event to intercept resource requests with custom scheme.
///
/// **Android** supports these additional options:
///
/// - __clearSessionCache__: Set to `true` to have the session cookie cache cleared before the new window is opened.
/// - __builtInZoomControls__: Set to `true` if the WebView should use its built-in zoom mechanisms. The default value is `false`.
/// - __displayZoomControls__: Set to `true` if the WebView should display on-screen zoom controls when using the built-in zoom mechanisms. The default value is `false`.
/// - __supportZoom__: Set to `false` if the WebView should not support zooming using its on-screen zoom controls and gestures. The default value is `true`.
/// - __databaseEnabled__: Set to `true` if you want the database storage API is enabled. The default value is `false`.
/// - __domStorageEnabled__: Set to `true` if you want the DOM storage API is enabled. The default value is `false`.
/// - __useWideViewPort__: Set to `true` if the WebView should enable support for the "viewport" HTML meta tag or should use a wide viewport. When the value of the setting is false, the layout width is always set to the width of the WebView control in device-independent (CSS) pixels. When the value is true and the page contains the viewport meta tag, the value of the width specified in the tag is used. If the page does not contain the tag or does not provide a width, then a wide viewport will be used. The default value is `true`.
/// - __safeBrowsingEnabled__: Set to `true` if you want the Safe Browsing is enabled. Safe Browsing allows WebView to protect against malware and phishing attacks by verifying the links. The default value is `true`.
/// - __textZoom__: Set text scaling of the WebView. The default value is `100`.
/// - __mixedContentMode__: Configures the WebView's behavior when a secure origin attempts to load a resource from an insecure origin. By default, apps that target `Build.VERSION_CODES.KITKAT` or below default to `MIXED_CONTENT_ALWAYS_ALLOW`. Apps targeting `Build.VERSION_CODES.LOLLIPOP` default to `MIXED_CONTENT_NEVER_ALLOW`. The preferred and most secure mode of operation for the WebView is `MIXED_CONTENT_NEVER_ALLOW` and use of `MIXED_CONTENT_ALWAYS_ALLOW` is strongly discouraged.
///
/// **iOS** supports these additional options:
///
/// - __disallowOverScroll__: Set to `true` to disable the bouncing of the WebView when the scrolling has reached an edge of the content. The default value is `false`.
/// - __enableViewportScale__: Set to `true` to allow a viewport meta tag to either disable or restrict the range of user scaling. The default value is `false`.
/// - __suppressesIncrementalRendering__: Set to `true` if you want the WebView suppresses content rendering until it is fully loaded into memory.. The default value is `false`.
/// - __allowsAirPlayForMediaPlayback__: Set to `true` to allow AirPlay. The default value is `true`.
/// - __allowsBackForwardNavigationGestures__: Set to `true` to allow the horizontal swipe gestures trigger back-forward list navigations. The default value is `true`.
/// - __allowsLinkPreview__: Set to `true` to allow that pressing on a link displays a preview of the destination for the link. The default value is `true`.
/// - __ignoresViewportScaleLimits__: Set to `true` if you want that the WebView should always allow scaling of the webpage, regardless of the author's intent. The ignoresViewportScaleLimits property overrides the `user-scalable` HTML property in a webpage. The default value is `false`.
/// - __allowsInlineMediaPlayback__: Set to `true` to allow HTML5 media playback to appear inline within the screen layout, using browser-supplied controls rather than native controls. For this to work, add the `webkit-playsinline` attribute to any `<video>` elements. The default value is `false`.
/// - __allowsPictureInPictureMediaPlayback__: Set to `true` to allow HTML5 videos play picture-in-picture. The default value is `true`.
