desktop_webview_window library

Classes

CreateConfiguration
JavaScriptMessage: A message from window.desktopWebview.postMessage(name, data) in the top-level document.
TitleBarOptions: What the default composer shows in the window's title bar, next to the system window buttons. An application composer receives the same choices in DWWComposeRequest::title_bar and may ignore them.
Webview: A browser window. Operations complete when native code has applied them and fail with a PlatformException when it reports an error. Operations a platform does not support throw UnsupportedError.
WebviewCookie
WebviewLoadError: A failed top-level navigation. Failures of subresources and iframes are not reported, nor are HTTP error responses, which load the server's page.
WebviewNavigationState: Current browser navigation state, the same state native composers receive.
WebviewWindow
WindowsWebviewOptions: Options that only WebView2 on Windows honours.

JavaScriptMessageHandler = void Function(Object? data, String origin): Receives window.desktopWebview.postMessage(name, data) from the top-level document. data is the JSON-decoded value.
JavaScriptMessageListener = void Function(JavaScriptMessage message): Receives a JavaScriptMessage. See Webview.addJavaScriptMessageHandler.
OnUrlRequestCallback = bool Function(String url): Decides whether the browser may navigate to url. Return false to cancel. The navigation waits for the callback, so it must answer synchronously; a callback that throws allows the navigation. Schemes the WebView cannot load, such as mixin:, reach the callback too; handle them and return false.
PromptHandler = String Function(String prompt, String defaultText)
