Can I inject js code before the document loads?

[uldaman]

evalJavaScript must be run after the page has finished loading. But i want to inject javascript code before the document loads. Reference:

WKUserScript(source: sourceJs, injectionTime: .atDocumentStart, forMainFrameOnly: false)

so do we provide this flutter api?

Same question, really need this :)

Didn't found that it is possible with the webview.. What I did to solve this is to create a special URL in my web app that will wait untill the webview injection is done, and then redirects to the requested flow.
