Summary

Three files in total was added in this PR

• docker compose file
• Dockerfile.linux
• Dockerfile.android
  Using these files we can run flutter in containerized environment in both android and linux. For android device, We can either run it in an emulator or through a connected android device. There may be some native device problems due to the adb setup. It can be fixed using:

adb kill-server

Check again for all connected emulators:

adb devices

• command to run in linux mode:

sudo docker-compose --profile linux up 

• command to run in android mode:

sudo docker-compose --profile android up 

• Added different files for android and linux as the android sdk is quite heavy and unneccesary for non-android emulators.

Checklist

• Tests have been added or updated to cover the changes

@BrawlerXull @Pavel401 I have added the containers and observed them to be running locally. I think there should be an update in the contributing file to add the functionality to run the app in containerized mode. Please let me know if anymore changes would be required. thank you.

Could you please share some outputs? Specifically, a screen recording demonstrating how this will benefit the contributors. I haven’t come across any open-source Flutter repositories that support Docker.

Of course @Pavel401 I will do a screenrecording and show how the docker is working to setup the entire project with just 1 command.
The main benifit is that the flutter, dart and android sdk versionsof many devices vary and due to that the app might not work in many local devices (already happened with me!), the only solution would be updating local version of them, but as open source contributors might need to maintain several applications with their own desired version, it would become very problematic to constantly keep changing local dependency versions. AlthoughFVM` solves the problem to an extent but i's still prone to many errors.
The best solution is to containerize the application using docker so that maintaining local version is not an issue any more!

About other flutter repos, they may not be that focused on open source contributors so they might not expect the developers to face the constant versioning problem i think... Nevertheless containerizing the app would definitely make it easier to get the app up and running in an instant without any versioning hassle. Thank you.
