I am a High School student who learns programming on his own. In the past, I have mostly focused on getting knowledge and experience in Web Development. Currently I focus on Mobile Development with Flutter. When it comes to complex Back-End , Golang is my favourite choice, although I am not such a masochist to choose it over simplicity, which Firebase provides! I am not a big fan of being only a 'code writer', that's the reason why I've been learning basics of Assembly language. I want to understand truely how the computer works, so I can code much better optimalized applications! Apart from technologies pointed out above, I've also spent a lot of time on getting experience with Dev-Ops stuff . I always prefer my app to be containerized and have better infrastructure overall. Previosuly I was using Docker for that, now my goal is to be confident with Kubernetes. I am also a Linux User, familiar with Arch and Ubuntu distros, so Operating Systems don't scare me either!

I am trying to restart flutter application running in Docker.

I specified stdin_open and tty to true in docker-compose.yml file
- This is the only one place in docker-compose.yml where I've specified stdin and tty.
```
app:
  build:
    context: app
  restart: always
  stdin_open: true
  tty: true
  volumes:
    - ./app:/build
  ports:
    - "8080:8080"
  env_file:
    - ./env/flutter.env
  command: >
    sh -c "flutter pub get
    && flutter run -d web-server --web-port 8080 --web-hostname 0.0.0.0"
  depends_on:
    - server
```
On the screen above it is visible that I cannot restart an application this way.

I have to do it manually by using command: docker-compose up --detach --build

Is there any way I can interact with this container and restart app by pressing "R" ?

  The docker-compose command you show is the normal way to do it.

It doesn't work either. Same result as before

@Wiktor can you provide some hello-world code so I can run flutter myself?

pastebin.com/qEAEcECN This is the simplest one main file, but you need a lot of more files to build it. With flutter sdk, you can run flutter create <name> to create a ready to run flutter template.

@Wiktor I tried many times to make it work with docker-compose but failed. It seems the only thing it forwards are process signals. On the other hand the solution I posted above worked well: i.imgur.com/LmBCXuy.png . I tried several launch configurations and there was no problem with restart by pressing R.

Oh, I am sorry. It works, that's right. I had to attach it before it started running in the browser. Thank you very much
