injectJavascriptFileFromUrl method

Future<void> injectJavascriptFileFromUrl({
  1. required WebUri urlFile,
  2. ScriptHtmlTagAttributes? scriptHtmlTagAttributes,
})

Injects an external JavaScript file into the WebView from a defined url.

scriptHtmlTagAttributes represents the possible the <script> HTML attributes to be set.

NOTE: This method shouldn't be called in the PlatformWebViewCreationParams.onWebViewCreated or PlatformWebViewCreationParams.onLoadStart events, because, in these events, the WebView is not ready to handle it yet. Instead, you should call this method, for example, inside the PlatformWebViewCreationParams.onLoadStop event or in any other events where you know the page is ready "enough".

NOTE for Web: this method will have effect only if the iframe has the same origin.
