Incompatible with latest CocoaPods version 1.15.1: No such module 'MLKitVision'

[toebgen]

When I try to build a clean Flutter app, created with flutter create (Flutter 3.16.9, channel stable), and add the mobile_scanner dependency to the pubspec.yaml: mobile_scanner: ^4.0.0, then I receive the above mentioned error:

Failed to build iOS app
Swift Compiler Error (Xcode): No such module 'MLKitVision'
/.../.pub-cache/hosted/pub.dev/mobile_scanner-4.0.0/ios/Classes/MobileScanner.swift:10:7

Uncategorized (Xcode): Command SwiftCompile failed with a nonzero exit code

I have the latest CocoaPods version installed, which is 1.15.1 as of today.

The mobile_scanner does not seem to be compatible with this version.

I can confirm this behavior.
When building with version 1.11.3 of CocoaPods it works, when updating CocoaPods to vesion 1.15.1 the above error occurs.

Hint: when using 1.11.3 the replacmenet of DT_TOOLCHAIN_DIR with TOOLCHAIN_DIR must be done manually (see e.g. here CocoaPods/CocoaPods#12012 (comment))

In the related Stackoverflow issue someone has hinted to this: https://stackoverflow.com/a/77419102/19807154.
It recommends to

import the standalone libraries individually, rather than importing the main module as a whole

Same issue I faced after updating cocapod at 1.15.1.

I believe there happened to be some regressions in 1.15.1 try updating to 1.15.2 and see if this happens.

Works with 1.15.2

Got the same error with pod 1.15.2

Got the same error with pod 1.15.2

May you share your flutter doctor? Also you could try flutter clean && flutter pub cache repair && flutter pub get and see if that fixes it
