Add Continuous Integration for Building APKs on Push to Main Branch

[Juanipis]

Currently, our Flutter project lacks a continuous integration (CI) setup to automate the build process for APKs. I propose adding a CI configuration (such as GitHub Actions, CircleCI, or any other CI tool) that triggers a build of the APK every time there is a push to the main branch. This would ensure that our main branch always has the latest APK build available, helping in faster testing and deployments.

Tasks:

1. Set up a CI configuration file (e.g., .yml for GitHub Actions).
2. Configure the CI pipeline to trigger on push events to the main branch.
3. Add steps to the pipeline for building the APK using Flutter commands.
4. Optionally, store the generated APK as an artifact or deploy it to a storage solution for easy access.

Benefits:

• Ensures consistent builds for the main branch.
• Reduces manual effort in generating APKs.
• Improves testing efficiency and deployment readiness.

Feel free to suggest improvements or alternative solutions for the CI setup.
