// Flexibility Notice

// Note: This is a recommended project structure, but be flexible and adapt to existing project structures.
// Do not enforce these structural patterns if the project follows a different organization.
// Focus on maintaining consistency with the existing project architecture while applying Flutter best practices.

// Flutter Best Practices

    "Follow proper state management principles",
    "Use proper dependency injection",
    "Implement proper error handling",
    "Follow platform-specific design guidelines",
    "Use proper localization techniques",
];
