Comment puis-je configurer un certificat SSL letsencrypt et l'utiliser dans un serveur https dans dart?

Question

J'essaie:

import 'dart:io'; 
import "dart:isolate"; 
main() { 
    SecurityContext context = new SecurityContext(); 
    var chain = Platform.script.resolve('/etc/letsencrypt/live/example.com/chain.pem').toFilePath(); 
    var key = Platform.script.resolve('/etc/letsencrypt/live/example.com/privkey.pem').toFilePath(); 
    context.useCertificateChain(chain); 
    // context.usePrivateKey(key, password: '?????'); 
    context.usePrivateKey(key); 

    HttpServer.bindSecure(InternetAddress.ANY_IP_V4, 443, context).then((server) { 
     server.listen((HttpRequest request) { 
      request.response.write('Hello, world!'); 
      request.response.close(); 
     }); 
    }); 
} 

Mais fonctionne pas! Des idées pour faire ce travail? https://api.dartlang.org/stable/1.24.2/dart-io/HttpServer-class.html#id_bindSecure

Message d'erreur:

J'ai trouvé la solution au problème: "Mais pas travailler"

import 'dart:io'; 
import "dart:isolate"; 

main() { 
    SecurityContext context = new SecurityContext(); 
    var chain = Platform.script.resolve('/etc/letsencrypt/live/www.example.com/fullchain.pem').toFilePath(); 
    var key = Platform.script.resolve('/etc/letsencrypt/live/www.example.com/privkey.pem').toFilePath(); 
    context.useCertificateChain(chain); 
    // Password not Required 
    context.usePrivateKey(key); 

    HttpServer.bindSecure(InternetAddress.ANY_IP_V4, 443, context).then((server) { 
     server.listen((HttpRequest request) { 
      request.response.write('Hello, world!'); 
      request.response.close(); 
     }); 
    }); 
}
