Limitations

This plugin provides seamless composition of web-based contents with other Flutter widgets by rendering off-screen.

Unfortunately, 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.
