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.addNamedType((NamedType node) {
    if (node.name.lexeme != 'DioError') return;
    // Only flag DioError in files that use dio, so an unrelated user-defined
    // DioError elsewhere is not mistaken for the removed package type.
    if (!fileImportsPackage(node, PackageImports.dio)) return;
    reporter.atNode(node);
  });
}
