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,
) {
  // Inverse of the web-gate pattern: this rule warns that `dart:html`
  // & friends crash at startup on mobile/desktop. A web-only project
  // (no android/ios/macos/windows/linux directories at the project
  // root) can't hit that failure mode, so every diagnostic is noise.
  // Pure Dart libraries default true (consumers' targets unknown).
  // See sibling bug report
  // bugs/platform_gate_missing_from_sibling_rules.md.
  if (!ProjectContext.hasNonWebPlatform(context.filePath)) return;

  context.addImportDirective((ImportDirective node) {
    final String? uri = node.uri.stringValue;
    if (uri == null) return;

    if (_webOnlyImports.contains(uri)) {
      // Check if it's a conditional import
      if (node.configurations.isNotEmpty) {
        return; // Conditional import is fine
      }
      reporter.atNode(node);
    }
  });
}
