Loading .css file after downloading it in local storage using InAppWebview flutter working in android but not on iOS

[neeluagrawal04]

I want to load the .css file after downloading it in local storage using inAppWebview.

Technology	Version
Flutter version	latest
Plugin version	latest
Android version	31
iOS version	17

0

I would like to load the contents of .css file which will contains the fonts like KaTeX_AMS-Regular.woff2

So, the css file contains the content like file main.css

@font-face{font-family:abcd_AMS;src:url(fonts/abcd_AMS-Regular.woff2) format("woff2"),url(fonts/abcd_AMS-Regular.woff) format("woff"),url(fonts/abcd_AMS-Regular.ttf) format("truetype");font-weight:400;font-style:normal}@font-face{font-family:abcd_Caligraphic;src:url(fonts/abcd_Caligraphic-Bold.woff2) format("woff2"),url(fonts/abcd_Caligraphic-Bold.woff) format("woff")

so these font file I am downloading at a file path and loading the html like this

destinationFilePath.path will be path where the contents of css are downloaded. File content will be like:

root --> content --> main.css

root --> content --> fonts --> abcd_Caligraphic-Bold.woff root --> content --> fonts --> abcd_Caligraphic-Bold.woff2 .. and so on

String htmlContent = """ $data """;

The above code works properly in android but it does not read the css font file contents in iOS.

I am using https://pub.dev/packages/flutter_inappwebview package to load the contents in webview.

InAppWebView( initialOptions: InAppWebViewGroupOptions( crossPlatform: InAppWebViewOptions( mediaPlaybackRequiresUserGesture: false, disableVerticalScroll : true, disableHorizontalScroll : true, disableContextMenu: true, useShouldOverrideUrlLoading: true, allowFileAccessFromFileURLs: true, allowUniversalAccessFromFileURLs: true), ios: IOSInAppWebViewOptions( allowsInlineMediaPlayback: true, allowingReadAccessTo: Uri.file(fontFilePath.path), ), ), initialData: InAppWebViewInitialData(data: htmlContent),

);

using the above code snippet, it will works perfectly fine in android but not on ios
