findProxy property
Sets the function used to resolve the proxy server to be used for
opening a HTTP connection to the specified url
. If this
function is not set, direct connections will always be used.
The string returned by f
must be in the format used by browser
PAC (proxy auto-config) scripts. That is either
"DIRECT"
for using a direct connection or
"PROXY host:port"
for using the proxy server host
on port port
.
A configuration can contain several configuration elements separated by semicolons, e.g.
"PROXY host:port; PROXY host2:port2; DIRECT"
The static function findProxyFromEnvironment
on HttpClient class can
be used to implement proxy server resolving based on environment
variables.
This will override the value set for findProxyAsync.
Implementation
@override
set findProxy(String Function(Uri url)? f) => _findProxy = f;
