runWithReporter method

@override void runWithReporter(SaropaDiagnosticReporter reporter, SaropaContext context)

Override this method to implement your lint rule.

Use context to register callbacks for AST node types:

context.addMethodInvocation((node) {
  if (condition) {
    reporter.atNode(node);
  }
});

Implementation

@override
void runWithReporter(
  SaropaDiagnosticReporter reporter,
  SaropaContext context,
) {
  context.addClassDeclaration((ClassDeclaration node) {
    // Check if extends Equatable
    final extendsClause = node.extendsClause;
    if (extendsClause == null) return;
    if (extendsClause.superclass.name.lexeme != 'Equatable') return;

    // Check for props getter
    bool hasProps = false;
    for (final member in node.bodyMembers) {
      if (member is MethodDeclaration &&
          member.isGetter &&
          member.name.lexeme == 'props') {
        hasProps = true;
        break;
      }
    }

    if (!hasProps) {
      reporter.atNode(node);
    }
  });
}
