You can do that with the https://pub.dev/packages/native_dio_adapter for iOS but I am not sure about the Android side which uses https://pub.dev/packages/cronet_http

But plain dio on Dart side does not support this.

As said in the comment above, dio itself can't and won't support this usecase. It is possible with the native adapter, or you can manually check what connection is currently active and make requests accordingly.

Hi @kuhnroyal , thanks for your information.
do you have example/reference for native dio adapter for ios, that forces cellular data?

I can't find any configuration that supports my issue above.
cronet_http doesn't have configuration-related force cellular data with cronet engine.
I don't think, native dio adapter also has this configuration for forcing cellular data.

At this time, I think the only solution on native side, using platform-specific channel

here is my reference on Android developer web.

Yea, you can actually only disallow cellular access with cupertino_http but you can not force it, my bad.
