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.addInstanceCreationExpression((InstanceCreationExpression node) {
    final String? constructorName = node.constructorName.type.element?.name;

    // Check TextStyle constructor
    if (constructorName != 'TextStyle') return;

    _checkFontSize(node.argumentList.arguments, reporter);
  });
}
