+
+A [Flutter](https://flutter.dev/) WebView plugin for Windows built on [Microsoft Edge WebView2](https://docs.microsoft.com/en-us/microsoft-edge/webview2/).
+
+
+### Target platform requirements
+- [WebView2 Runtime](https://developer.microsoft.com/en-us/microsoft-edge/webview2/)  
+  Before initializing the webview, call `getWebViewVersion()` to check whether the required **WebView2 Runtime** is installed or not on the current system. If `getWebViewVersion()` returns null, guide your user to install **WebView2 Runtime** from this [page](https://developer.microsoft.com/en-us/microsoft-edge/webview2/).
+- Windows 10 1809+
+
+### Development platform requirements
+- Visual Studio 2019 or higher
+- Windows 11 SDK (10.0.22000.194 or higher)
+- (recommended) nuget.exe in your $PATH *(The makefile attempts to download nuget if it's not installed, however, this fallback might not work in China)*

+
+
+## Limitations
+This plugin provides seamless composition of web-based contents with other Flutter widgets by rendering off-screen.
+
+Unfortunately, [Microsoft Edge WebView2](https://docs.microsoft.com/en-us/microsoft-edge/webview2/) doesn't currently have an explicit API for offscreen rendering.
+In order to still be able to obtain a pixel buffer upon rendering a new frame, this plugin currently relies on the `Windows.Graphics.Capture` API provided by Windows 10.
+The downside is that older Windows versions aren't currently supported.
+
+Older Windows versions might still be targeted by using `BitBlt` for the time being.
