runWithReporter method

  1. @override
void runWithReporter(
  1. SaropaDiagnosticReporter reporter,
  2. SaropaContext context
)
override

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.addMethodInvocation((MethodInvocation node) {
    final String methodName = node.methodName.name;
    if (!_dbMethods.contains(methodName)) return;

    final Expression? target = node.target;
    if (target == null) return;

    final String targetSource = target.toSource().toLowerCase();
    if (!_dbTxnTargetPatterns.any((p) => p.hasMatch(targetSource))) {
      return;
    }

    // Check if inside try-catch
    AstNode? current = node.parent;
    while (current != null) {
      if (current is TryStatement) return;
      if (current is FunctionBody) break;
      current = current.parent;
    }

    reporter.atNode(node);
  });
}
