FormatException (FormatException: Unexpected extension byte (at offset 9504)) for certain valid urls

[mlars84]

I keep hitting this FormatException from convert_patch.dart when https://www.google.com/ is the passed as the link. Code example:

AnyLinkPreview(
  link: "https://www.google.com",
  cache: Duration(hours: 1),
  backgroundColor: Colors.grey[300],
  errorWidget: Container(
    color: Colors.grey[300],
    child: Text('Oops!'),
  ),
);

https://www.google.com/ is an unlikely use case and not particularly concerning, but it is concerning that AnyLinkPreview is getting stuck in a loading state rather than handling this more gracefully. I am on Flutter 2.2.2 and using any_link_preview ^2.0.0-rc.

If I run the example from the repo I am also getting Web page resolution failure from:https://www.google.com Error:FormatException: Bad GBK encoding 0xd00c. I'm assuming this is due to how the document body is being parsed and google being an outlier, but is there concern that this could be a common issue with url's?

@sur950 Removing br from accept-encoding list of headers seems to fix this issue

any_link_preview/lib/web_analyzer.dart

Line 186 in 5580f47

..headers["accept-encoding"] = "gzip, deflate, br"

Hi @mlars84 Thanks for reporting the bug.

@ghpranav Could you raise a PR for the same, I will merge that instantly, Working on own product & not finding enough time for the support.

Cheers,
Suresh
