google_mlkit_image_labeling and google_mlkit_text_recognition not working for Firebase hosted models

[igniti0n]

Describe the bug

Using packages google_mlkit_image_labeling: ^0.4.0 and google_mlkit_text_recognition: ^0.4.0 with custom Firebase hosted ML models fails on pod install

Getting different kinds of errors, like so:

Steps to reproduce

Try to use the package google_mlkit_image_labeling: ^0.4.0, adding the additional required setup for hosting Firebase models.

Podfile:

# Uncomment this line to define a global platform for your project
platform :ios, '10.0'

# Enable firebase-hosted models #
pod 'GoogleMLKit/LinkFirebase'
pod 'Firebase'

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'

project 'Runner', {
  'Debug' => :debug,
  'Profile' => :release,
  'Release' => :release,
}

def flutter_root
  generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
  unless File.exist?(generated_xcode_build_settings_path)
    raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
  end

  File.foreach(generated_xcode_build_settings_path) do |line|
    matches = line.match(/FLUTTER_ROOT\=(.*)/)
    return matches[1].strip if matches
  end
  raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
end

require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)

flutter_ios_podfile_setup

target 'Runner' do
  use_frameworks!
  use_modular_headers!

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end

# add this line:
$iOSVersion = '10.0'

post_install do |installer|
   # add these lines:
  installer.pods_project.build_configurations.each do |config|
    config.build_settings["EXCLUDED_ARCHS[sdk=*]"] = "armv7"
    config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = $iOSVersion
  end

  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)

    # add these lines:
    target.build_configurations.each do |config|
        if Gem::Version.new($iOSVersion) > Gem::Version.new(config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'])
          config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = $iOSVersion
        end
    end

    target.build_configurations.each do |config|
        # Enable firebase-hosted ML models
        config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
          '$(inherited)',
          'MLKIT_FIREBASE_MODELS=1',
        ]
      end

  end
end
