## 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.
