Cannot run example app

[mathschy]

Hello,

I am trying to use this plugin for OCR.

I can't run the example app. I just git-cloned this repo, launched an iOS simulator and did flutter run and here is the output:

Xcode's output:

Could not build the application for the simulator.
Error launching application on iPhone SE (1st generation).

The error seems to be ld: framework not found FirebaseAnalytics (why does it need FirebaseAnalytics by the way ? seems unrelated to google_ml_kit ?)

Here is my flutter doctor

How do you manage to run the example app ?

Hello @mathschy, were you able to run it on iOS? I am facing a problem on a previous step. I created an issue #194

Try the latest version.

Also note that google_ml_kit has been split in multiples plugins, to avoid adding unnecessary dependencies to your project.
