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.addNamedExpression((NamedExpression node) {
    if (node.name.label.name != 'markers') return;

    // Check if using .map() to create markers from a collection
    final Expression value = node.expression;
    final String valueSource = value.toSource();

    // Look for patterns that suggest many markers
    if (valueSource.contains('.map(') && valueSource.contains('Marker')) {
      reporter.atNode(node);
    }
  });
}
