Google's ML Kit for Flutter

Google's ML Kit for Flutter is a set of Flutter plugins that enable Flutter apps to use Google's standalone ML Kit.

In versions 0.7.3 and earlier all features were included in a single plugin, but a lot of developers started to get issues with the size of their apps, because even though they only needed a single feature, the plugin included all the resources for the rest of the features, that increased the size of the app significantly.

In recent versions we have split the plugin in multiple plugins to allow developers to use only what they need. google_ml_kit now is an umbrella plugin including all of the plugins. Start using or migrate to the new plugins to use only what you need. Go to each plugin to read about their requirements. If you find issues report and contribute with your pull requests.

Requirements

iOS

Minimum iOS Deployment Target: 10.0
Xcode 13 or newer
Swift 5
ML Kit only supports 64-bit architectures (x86_64 and arm64). Check this list to see if your device has the required device capabilities.

Since ML Kit does not support 32-bit architectures (i386 and armv7) (Read mode), you need to exclude amrv7 architectures in Xcode in order to run flutter build ios or flutter build ipa.

Go to Project > Runner > Building Settings > Excluded Architectures > Any SDK > armv7

Then your Podfile should look like this:

# 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
    
  end
end

Notice that the minimum IPHONEOS_DEPLOYMENT_TARGET is 10.0, you can set it to something newer but not older.

Android

minSdkVersion: 21
targetSdkVersion: 29
