Interview Questions
Both packages are widely used and effective for Flutter connectivity with backend(Nodejs etc), but the choice between them often depends on the specific requirements of your project. Most of the time http fulfill all requirements but for ‘formdata’ and other complex techniques either we use both or dio only. If you need advanced features like request/response interceptors, request cancellation, FormData support, or more robust error handling, dio might be a good choice. On the other hand, if you’re looking for a simpler, lightweight solution and don’t need the additional features, http could be sufficient.
