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.addMethodDeclaration((MethodDeclaration node) {
    // Skip build method
    if (node.name.lexeme == 'build') return;

    if (_isNullableWidgetReturn(node.returnType)) {
      reporter.atToken(node.name, code);
    }
  });

  // Also check function declarations (top-level functions)
  context.addFunctionDeclaration((FunctionDeclaration node) {
    if (_isNullableWidgetReturn(node.returnType)) {
      reporter.atToken(node.name, code);
    }
  });
}
