flutter_cached_network_image Headers are being ignored on Web platform

🐛 Bug Report

Trying to add a token to the request headers but it's not being added

Expected behavior

Token is added to the request headers

Reproduction steps

final headers = {"Authorization": "Bearer #token# "};

CachedNetworkImage( width: _width, height: _height, imageUrl: imageUrl ?? '', httpHeaders: headers, placeholder: (context, url) => CircularProgressIndicator(), errorWidget: (context, url, error) { print (error.toString()); return Icon(Icons.error);}, imageBuilder: (context, image) => CircleAvatar( backgroundImage: image, radius: 150, ), ),

Also tried to use http client with an interceptor http_interceptor: ^1.0.2 but failed as well:

final client = InterceptedClient.build(interceptors: [ CachedImageInterceptor(_token), ]);

cacheManager: CacheManager( Config( 'cached_images', fileService: HttpFileService( httpClient: client, ), ), ),

In both cases the header is not added. Looks like headers are ignored or http client is overridden at some point later
