title: Dockerize flutter web application
body: <p>I'm trying to Dockerize my flutter web application. I have tried with many images, like use debian and download and install flutter on it, use unnoficial images like haizen/flutter or cirrusci/flutter. But in all attempts it's returning an exception that is not appearing when i'm running manually the build.</p>
  <p>Here's my Dockerfile:</p>
  <pre><code># Install flutter
  FROM haizen/flutter:2.10.2-1-alpine AS build-env
  
  # Run flutter doctor and enable web
  RUN flutter doctor
  RUN flutter config --enable-web
  
  # Copy files to container and build
  USER root
  RUN mkdir /app/
  COPY . /app/
  WORKDIR /app/
  RUN flutter build web
  
  # Stage 2 - Create the run-time image
  FROM nginx:1.21.1-alpine
  COPY --from=build-env /app/build/web /usr/share/nginx/html
  </code></pre>
  <p>And this is the problem, running on GitHub Actions.  I've tried running it on my machine too, with the same problem:</p>
