[feat] Implemented GH-Actions for static code analysis

[opxdelwin]

PR Description:

This PR addresses the issue titled #186. Previously, GitHub Actions were not enabled for automating static Flutter Code Analysis in this project.

Feature Implemented:

To resolve this, a pipeline has been established to test relevant commits for code analysis issues. This ensures that code quality is maintained consistently throughout the development process.

Moving forward, any analysis issues identified will be fixed within the main Actions PR itself, ensuring that our codebase remains clean and maintainable.

Future

• Implement flutter test as part of workflow.

Awaiting everyone's valuable feedback.
