How to config Dnsmasq for local develop?

I try to use docker to run my server in local and use dnsmasq to able to receive requests from others devices in the local network.

But it does not work.

Is there anything wrong?

These are my project:

network/
├── nginx/
│   ├── sample.d/
│   │   └── sample.conf
│   └── nginx.conf
├── sample_server/
│   ├── Dockerfile
│   ├── api.py
│   └── requirements.txt
├── dnsmasq/
│   └── dnsmasq.conf
└── docker-compose.yml

dnsmasq.conf:

log-queries
no-resolv
strict-order

server=1.0.0.1
server=1.1.1.1

server=/demo.me/127.0.0.1
address=/demo.me/192.168.2.31

nginx.conf:

# user       www www;  ## Default: nobody
worker_processes  1;  ## Default: 1
# error_log  logs/error.log;
# pid        logs/nginx.pid;
worker_rlimit_nofile 8192;

events {
  worker_connections  1024;
}

http {
  index    index.html index.htm index.php;

  default_type application/octet-stream;
  log_format   main '$remote_addr - $remote_user [$time_local]  $status '
    '"$request" $body_bytes_sent "$http_referer" '
    '"$http_user_agent" "$http_x_forwarded_for"';
  sendfile     on;
  tcp_nopush   on;
  server_names_hash_bucket_size 128; # this seems to be required for some vhosts

  upstream big_server_com {
    server 127.0.0.3:8000 weight=5;
    server 127.0.0.3:8001 weight=5;
    server 192.168.0.1:8000;
    server 192.168.0.1:8001;
  }

  include sample.d/*;
}

sample.conf:

server {
    listen 80;
    server_name demo.me;
    location / {
        proxy_set_header Host $host;
        proxy_pass http://sampleserver:5000;
    }
}

docker_compose.yml:

networks:
  test-network:
    external: true

services:
  nginx:
    restart: always
    container_name: sample_nginx
    image: nginx
    networks:
      - test-network
    ports:
      - "80:80"
    volumes:
      - ./nginx/nginx.conf:/etc/nginx/nginx.conf
      - ./nginx/sample.d:/etc/nginx/conf.d
    depends_on:
      - sampleserver

  dns:
    container_name: dnsmasq
    restart: always
    image: dockurr/dnsmasq
    volumes:
      - ./dnsmasq/dnsmasq.conf:/etc/dnsmasq.conf
    ports:
      - 53:53/tcp
      - 53:53/udp
    cap_add:
      - NET_ADMIN
    networks:
      - test-network

  sampleserver:
    container_name: sample_server
    image: be-flask-python-3-12:1.0.0
    volumes:
      - ./sample_server/:/app/
    networks:
      - test-network
    command: 
      - api.py

I also added “127.0.0.1 demo.me” to /etc/hosts but I still can not receive request http://demo.me/ from another device in the local network.
