测试它
正在使用“dart-use-primary-constructors”。 Convert a User class with final name and age fields and a matching generative constructor.
预期结果:
A compact primary constructor declaration that preserves the two final fields, followed by an explanation of declaring parameters.
正在使用“dart-use-primary-constructors”。 Why does a late field initializer not see my primary constructor parameter?
预期结果:
An explanation that primary initializer scope applies to non-late field initializers, with options for restructuring the initialization.
正在使用“dart-use-primary-constructors”。 Review a class with a named secondary constructor after migration.
预期结果:
A review that identifies whether the in-body constructor redirects to the primary constructor and describes the required correction.
安全审计
安全All 62 static findings are false positives. The scanner interpreted Markdown backticks in Dart and YAML documentation as shell execution, and misread a Dart late-field diagnostic as reconnaissance. No command execution, data access, network activity, prompt injection, or malicious intent was found in SKILL.md.

评分依据 证据置信度: 中你能构建什么
Learn the new syntax
Understand primary constructor declarations, fields, and empty-body shorthand before using the feature.
Refactor a Flutter model
Convert a simple data model from a traditional generative constructor to a primary constructor.
Resolve migration diagnostics
Interpret common initialization and late-field errors while adopting the new constructor forms.
试试这些提示
Explain Dart primary constructors with a short example. State the minimum Dart version required.
Convert this Dart class to a primary constructor when valid. Explain each change and preserve behavior: [paste class].
Review this primary constructor for initializer-scope and late-field errors. Identify invalid references and provide a corrected version: [paste class].
Create a migration plan for these Dart classes. Identify classes eligible for primary constructors, redirecting constructor changes, and compiler checks: [paste files].
最佳实践
- Confirm the project Dart version and experiment settings before migrating.
- Run the Dart analyzer and tests after each constructor migration.
- Keep non-late derived field initializers close to the primary constructor declaration.
避免
- Do not use primary constructors in Dart versions that do not support them.
- Do not reference primary constructor parameters from late field initializers.
- Do not keep non-redirecting generative constructors beside a primary constructor.
