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.addClassDeclaration((node) {
    final members = node.bodyMembers;
    if (members.length < 2) return;

    for (int i = 0; i < members.length - 1; i++) {
      final current = members[i];
      final next = members[i + 1];

      final currentLine = context.lineInfo
          .getLocation(current.end)
          .lineNumber;
      final nextLine = context.lineInfo.getLocation(next.offset).lineNumber;

      if (nextLine - currentLine >= 2) {
        reporter.atNode(next);
      }
    }
  });
}
