preferences_generator 2.0.0

preferences_generator: ^2.0.0 copied to clipboard

This is a major architectural overhaul of the Preferences Suite, introducing a more powerful, flexible, and intuitive API. The core focus of this release is to simplify the PrefsAdapter, automate serialization, and provide extensive configuration options for the generated code.

🚀 Features #

• Added: Schema-in-Constructor API. Preference schemas are now defined in a private, generative constructor (e.g., MySettings._({...})) instead of a factory. This enables the use of standard Dart default values.
• Added: @PrefsModule Presets. Introduced powerful presets like .dictionary(), .syncOnly(), and .reactive() to quickly configure the generated API to match common storage backend patterns.
• Added: Automatic Serialization. The generator now automatically handles the serialization of complex types (DateTime, Duration, Enum, Record, and custom types via PrefConverter). The PrefsAdapter is now only responsible for handling primitive types.
• Added: Stream Generation. Added the ability to generate reactive Streams for any preference entry via the .reactive() preset or a custom streamer configuration.
• Added: Global build.yaml Configuration. You can now define project-wide settings, such as key_case: snake, to enforce conventions across all preference modules.
• Added: KeyCase Convention. Introduced the keyCase property in @PrefsModule and build.yaml to automatically transform generated storage keys to snake_case, kebab-case, etc.
• Added: Custom PrefConverter Support. Added the converter property to @PrefEntry to allow users to provide a reusable class for serializing and deserializing complex custom types.
• Added: Fine-Grained Method Configuration. Introduced CustomConfig, AffixConfig, and NamedConfig objects to allow precise control over every generated method's name and behavior, including enabling/disabling individual methods.

💥 Breaking Changes #

• Refactored: The schema definition has moved from a factory constructor to a private generative constructor. The old factory-based schema is no longer supported.
• Renamed: The PreferenceAdapter interface has been renamed to PrefsAdapter.
• Simplified: The contract for PrefsAdapter has been radically simplified. It is now only required to handle primitives (String, int, double, bool, List<String>). All manual serialization logic for complex types must be removed from adapter implementations.
• Removed: The containsKey() method has been removed from the adapter interface.
• Renamed: The clear() method in the adapter interface has been renamed to removeAll().
• Changed: The @PreferenceEntry(defaultValue: ...) property has been removed. Default values must now be provided using standard Dart syntax in the schema constructor (e.g., String username = 'guest').
• Changed: Generated method names are now more explicit and configurable. A field named theme will now generate methods like getTheme() and setTheme(...) instead of a top-level theme
• getter/setter pair.

🐛 Bug Fixes & Improvements #

• Improved: Code generation for collection literals (const [], const {}) now automatically infers and adds the correct type arguments to prevent type errors in the generated code.
• Improved: The entire generator codebase has been refactored into a more robust and testable architecture, separating analysis, model-building, and code generation into distinct, decoupled phases.
• Improved: Error messages are now more consistent and are all centralized in a dedicated ExceptionHandler class.
• Fixed: Resolved several bugs related to nullable type handling in setters and deserialization logic.
