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 String typeName = node.constructorName.type.name.lexeme;
    if (typeName != 'FileImage') return;

    // FP fix: `contains('asset')` matched any filesystem path that merely
    // happened to include those letters (e.g. `/var/dataset/photo.png`),
    // and `contains('assets/')` matched it mid-path too. A bundled asset is
    // referenced by a path that STARTS with `assets/`. Look for a string
    // literal argument (the File path) whose value begins with `assets/`.
    if (node.argumentList.arguments.isEmpty) return;
    final Expression first = node.argumentList.arguments.first;
    if (_referencesBundledAssetPath(first)) {
      reporter.atNode(node.constructorName, code);
    }
  });
