start method
Starts a local proxy that forwards traffic through the given
transportConfig.
See
https://pkg.go.dev/golang.getoutline.org/sdk/x/configurl#hdr-Config_Format
for the configuration string format (e.g. Shadowsocks URLs, split:,
socks5://, chained transports, etc).
localAddress is the address the local proxy listens on. Use port 0
(the default) to let the OS pick a free port.
Implementation
Future<ProxyInfo> start({
required String transportConfig,
String localAddress = '127.0.0.1:0',
}) {
throw UnimplementedError('start() has not been implemented.');
}
