Flutter webview with innerHTML callback issue

I am calling a webview, lets call it main index.html that has a JS file with displayAlert() method. It has another index.html as its innerHTML(this is inside a test folder). Whenever i call await webViewController.runJavascript("displayAlert()");, it gives Uncaught ReferenceError : displayAlert is not defined, source:file"///PATH_TO_ANDROID_STORAGE/test/index.html Somehow the callback is being forwarded to innerHTML instead of main index.html processing it. This happens only on android and not on iOS. I am using "https://pub.dev/packages/webview_flutter"

If I'm reading correctly, you are importing index.html from assets that has a <Script> tag with a link to another asset file.

As of December 2022 This does not work in Flutter WebView.

You need to embed your JS file code into the actual index.html or link to a public resource on the web, i.e. <script src="https://example.tld/my.js"></script>
