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 DartType? type = node.staticType;
    if (type is! InterfaceType) return;
    if (type.element.name != 'Container') return;
    final String uri = type.element.library.uri.toString();
    if (!uri.contains('flutter')) return;

    final Set<String> namedArgNames = <String>{};
    for (final Argument arg in node.argumentList.arguments) {
      if (arg is NamedArgument) {
        namedArgNames.add(arg.name.lexeme);
      }
    }

    if (namedArgNames.any(_containerJustifyingArgNames.contains)) return;

    reporter.atNode(node);
  });
}
