Hi, I was doing a size analysis of my app, and it looks like the Flutter SDKs are around 10 MB each, which seems a bit much. Can someone on the RevenueCat team look into this?

 

From `flutter build ipa --release --analyze-size`

      RevenueCatUI.framework                                               10 MB

      RevenueCat.framework                                                 10 MB

Hi ​@pkrs,

Thank you for sharing it! I’ve shared it with the team and we are working on reducing the SDK size. It should be a total size of 10mb for both frameworks and it’s a bit less when users install the app on their devices. Still, we are working to lower it down since it is not as lightweight as we would like to. I don’t have an ETA but it’s something we are actively working on at this moment.

 

Best,

We’re seeing the same issue on our side as well — the SDK size is quite noticeable in Flutter apps, especially for projects where binary size is a key constraint.

Glad to hear this is being actively worked on. Looking forward to any progress or updates on size optimization, as this would be very helpful for teams shipping Flutter apps at scale.
