[Feat] Integrate Flutter Lints into the CI/CD Pipeline

**Is your feature request related to a problem? Please describe.**
Currently, code style and linting rules are not automatically enforced during the CI/CD process. This can lead to inconsistencies in code quality, missed best practices, and potential bugs in the application.

**Describe the solution you'd like**
Integrate Flutter lints into the CI/CD pipeline to ensure that all commits and pull requests adhere to the project's linting rules. The pipeline should:
1. Run flutter analyze during the build process.
2. Fail the build if any linting issues are detected.

Start by inspecting the repository's existing CI configuration and Flutter project setup; the issue does not name specific files or a CI provider. Run `flutter analyze` locally to understand the expected check. Done means the CI pipeline runs this command for builds or pull requests and fails when linting issues are detected.
