Tester
Utilisation de « dart-use-primary-constructors ». Explain whether primary constructors are available in Dart 3.12.
RĂ©sultat attendu:
Dart 3.12 treats primary constructors as experimental. Enable the primary-constructors experiment in analyzer configuration or with the compiler flag.
Utilisation de « dart-use-primary-constructors ». Migrate a user model with final name and age fields.
RĂ©sultat attendu:
Move both final fields into the class header as declaring parameters. Remove the duplicate field declarations and constructor, then use a semicolon body.
Utilisation de « dart-use-primary-constructors ». Explain why a late field cannot use a primary constructor parameter.
RĂ©sultat attendu:
Primary initializer scope excludes late field initializers because they may run after construction. Store the value in a non-late field first.

Learn Primary Constructor Syntax
Understand parameter types, semicolon bodies, initializer scope, and version requirements through focused explanations.
Migrate Existing Models
Convert verbose data classes while preserving fields, assertions, calculations, and redirecting constructors.
Review Constructor Refactors
Identify scope violations, duplicate initialization, late-field errors, and invalid generative constructors before integration.
Essayez ces prompts
Explain Dart primary constructors for a beginner, including supported versions and the three parameter types.
Convert this Dart class to a primary constructor and explain each change: [class source].
Review this primary constructor, identify compile-time errors, and propose a corrected version: [class source].
Design a migration for these related Dart classes while preserving inheritance, redirects, assertions, public APIs, and SDK compatibility: [sources].
Bonnes pratiques
- Confirm the project Dart version before suggesting primary constructor syntax.
- Preserve assertions, initialization order, redirects, and public behavior during migration.
- Run the Dart analyzer and relevant tests after applying a generated refactor.
Éviter
- Do not use primary constructor parameters inside late field initializers.
- Do not initialize the same field in both its declaration and initializer list.
- Do not add a nonredirecting generative constructor beside a primary constructor.
