Local HTML bug

[HaijunWei]

I loaded an HTML from the sandbox and found that the css file was not loaded. I found a problem after reading the source code. In FlutterWebviewPlugin.m line 109

[self.webview loadFileURL:htmlUrl allowingReadAccessToURL:htmlUrl];

If allowingReadAccessToURL is a directory, the css file can be loaded.
Is it possible to add a directory parameter to allowingReadAccessToURL？

I'm also having this issue, assets won't load from the cache directory. Is there a way to pass the value to the allowingReadAccessToURL parameter of WKWebView?

There's not but I'm happy to add parameters if someone will tell me what and how to add it (also, PRs are more than welcomed)

You can add a parameter for launch and reloadUrl.
eg:

flutterWebViewPlugin.launch(htmlURL, readAccessToURL: xxxx)
flutterWebViewPlugin.reloadUrl(htmlURL, readAccessToURL: xxxx)

in In FlutterWebviewPlugin.m line 143 or line 193...199

NSURL *readAccessToURL = [NSURL fileURLWithPath:call.arguments[@"readAccessToURL"]];
[self.webview loadFileURL:htmlUrl allowingReadAccessToURL:readAccessToURL];
