Veelgestelde vragen

Quick answers.

Does this support Null Safety?

Yes. The generated code uses non-nullable types and required parameters where appropriate, matching modern Dart 2.12+ and Flutter standards.

How are nested JSON objects handled?

The tool recursively creates separate Dart classes for every nested object it finds to ensure your data model remains modular and clean.

Can I customise the root class name?

Yes. You can specify the name of the base class to match your data entity, such as `User` or `ProductResponse`.

Is my data sent to a server?

No. The conversion logic runs entirely within your browser sessions. Your JSON structure and variable names are never transmitted to our servers.
