### Code style and structure
- Write concise and efficient source code.
- Strive for source code that is easy to read and maintain, and provide accurate examples.
- Avoid duplication of code: modularise widgets and functions into reusable components.
- Use descriptive variable names: use names with auxiliary verbs such as isLoading, hasError.

### Directory structure under /lib.
- /lib/models/: data models and type definitions (Models)
- /lib/viewmodels/: state management and business logic (ViewModel)
- /lib/views/widgets/: reusable widgets (View)
- /lib/views/screens/: per-screen widgets (View)
- /lib/services/: service classes for API calls and data access
- /lib/utils/: helper functions and constants

### Naming conventions
- Directories and files: use snakeCase (e.g. auth_wizard.dart).
- UpperCamelCase: use for class names/enumerations/typedefs/type parameters, etc.
- LowerCamelCase: used for variables/functions/class members (properties, methods), etc.
- lowercase_with_underscores (snakeCase): for files/directories/packages/libraries, etc.

### Import.
- Place imports starting with dart: first (use lowercase_with_underscores for the import prefix).
