Use Firebase 9.6.0. MLKit is not currently compatible with Firebase 10.x.

  • but firebase latest version on pub dev is firebase_auth: ^4.2.8, because I'm using it on flutter, so which version I should follow on flutter – Waqas Farooq Feb 20 '23 at 10:01

  1. Create MLKitVision.podspec.json in ios folder taking content from this file here

  2. Create MLKitCommon.podspec.json in ios folder taking content from this file here

  3. Modify in both files the GTMSessionFetcher/Core definition from 1.1 to version 2.1.

  4. Inside your Podfile for the target 'project-name' you have to add at the end the following lines:

    pod 'MLKitVision', :podspec => 'MLKitVision.podspec.json'

    pod 'MLKitCommon', :podspec => 'MLKitCommon.podspec.json'

  5. Run pod install

  6. build the app
