Não consigo acessar o localhost através do ip.

Não é possível acessar o localhost através do IP da máquina, quando tento através do flutter encontro o erro abaixo, quando tento direto no navegador vou parar na página de acesso ao roteador da NET. Imagino que seja alguma configuração da minha rede que impeça conexões externas. Tem alguma alternativa para seguir o curso?
