Does this mean it's under the 10mb limit now to use in production?
@xster any updates on when this will be addressed?
Reacted by Erwan Jesson Ripoll, Pantao, otozyon, Ioannis Kokkinidis and Ash ZarifCorrect, it's still over 10mb currently unfortunately. I don't have an ETA for when it'll be addressed.
Reacted by James Howe@xster bump :). (since it's been 2 months since request for info and 6 months since your last comment hope you don't mind gentle bump

Targeting iOS 17 increases the limit to 15MB;
From that WWDC video:
If you'd like to make use of physical invocations, such as those through NFC tags or App Clip codes, you'll have to keep to the 15 MB limitation introduced in iOS 16.
So targeting iOS 16 allows the 15MB limit.

If doing an App Clip with Flutter could possibly be very limited by the size, would it be possible to create a Native AppClip(iOS)/Instant App(Android) within a Flutter Project?

Yes, just implement it natively

Yes, as you can see I wrote about that earlier. It's just another target in xcode, and that will use a separat prov profile. All those kind of stuff is well documented on apples dev site.
Note, android instant apps does not support the nfc api (or at least it didn't some time ago), if you intend to use that for app clip invocation.
Please update the flutter webpage describing use of iOS App Clip

on Apr 5, 2024 Hey @xster, is there anything we can do to help move this forward?
Our App Clip (uncompressed, thinned) is currently at 14.9 MB (even after switching out
MaterialAppforWidgetsApp). Happy to try and help to reduce Flutter engine size and overall iOS build size [with guidance]P.S. I noticed that App Thinning doesn't seem to help much -- the IPA size for Universal variant is equal to the IPA size for all compatible variants. Is this something you've seen before, and if so, does it imply that we've misconfigured something?
Is there any updates on whether we can expect App Clip with Flutter apps?
