Implementation

@override
void run(
  CustomLintResolver resolver,
  DiagnosticReporter reporter,
  CustomLintContext context,
) {
  context.registry.addInstanceCreationExpression((node) {
    if (isExpressionExactlyType(node, 'Container', 'flutter') &&
        isInstanceCreationExpressionOnlyUsingParameter(
          node,
          parameter: 'alignment',
          // Ignores key and child parameters because both Container and Align have them
          ignoredParameters: const {'key', 'child'},
        )) {
      reporter.atNode(node.constructorName, code);
    }
  });
