Add to podsec file a ruby script - ios

Question

I'm currently trying to create a framework that relies in an external module.
That module can be added via the following script in the Podfile:
flutter_application_path = './flutter_embedding'
eval(File.read(File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb')), binding)
(You can read more about this implementation here
This works fine if I run it, however, when running pod spec lint I get the following error:
- ERROR | [iOS] xcodebuild: FlutterIosFramework/flutter_ios_framework/AppDelegate.swift:10:8: error: no such module 'Flutter'
This error does not occur if I run the project normally.
So the question is, what can I do to include in the podspec file this external module that is added by a script?
If it helps, the script that is used in the snippet above is the following:
def parse_KV_file(file, separator='=')
file_abs_path = File.expand_path(file)
if !File.exists? file_abs_path
return [];
end
pods_array = []
skip_line_start_symbols = ["#", "/"]
File.foreach(file_abs_path) { |line|
next if skip_line_start_symbols.any? { |symbol| line =~ /^\s*#{symbol}/ }
plugin = line.split(pattern=separator)
if plugin.length == 2
podname = plugin[0].strip()
path = plugin[1].strip()
podpath = File.expand_path("#{path}", file_abs_path)
pods_array.push({:name => podname, :path => podpath});
else
puts "Invalid plugin specification: #{line}"
end
}
return pods_array
end
def flutter_root(f)
generated_xcode_build_settings = parse_KV_file(File.join(f, File.join('.ios', 'Flutter', 'Generated.xcconfig')))
if generated_xcode_build_settings.empty?
puts "Generated.xcconfig must exist. Make sure `flutter packages get` is executed in #{f}."
exit
end
generated_xcode_build_settings.map { |p|
if p[:name] == 'FLUTTER_ROOT'
return p[:path]
end
}
end
# If this wasn't specified, assume it's two levels up from the directory of this script.
flutter_application_path ||= File.join(__dir__, '..', '..')
framework_dir = File.join(flutter_application_path, '.ios', 'Flutter')
engine_dir = File.join(framework_dir, 'engine')
if !File.exist?(engine_dir)
# Copy the debug engine to have something to link against if the xcode backend script has not run yet.
debug_framework_dir = File.join(flutter_root(flutter_application_path), 'bin', 'cache', 'artifacts', 'engine', 'ios')
FileUtils.mkdir_p(engine_dir)
FileUtils.cp_r(File.join(debug_framework_dir, 'Flutter.framework'), engine_dir)
FileUtils.cp(File.join(debug_framework_dir, 'Flutter.podspec'), engine_dir)
end
pod 'Flutter', :path => engine_dir
pod 'FlutterPluginRegistrant', :path => File.join(framework_dir, 'FlutterPluginRegistrant')
symlinks_dir = File.join(framework_dir, '.symlinks')
FileUtils.mkdir_p(symlinks_dir)
plugin_pods = parse_KV_file(File.join(flutter_application_path, '.flutter-plugins'))
plugin_pods.map { |r|
symlink = File.join(symlinks_dir, r[:name])
FileUtils.rm_f(symlink)
File.symlink(r[:path], symlink)
pod r[:name], :path => File.join(symlink, 'ios')
}
# Ensure that ENABLE_BITCODE is set to NO, add a #include to Generated.xcconfig, and
# add a run script to the Build Phases.
post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['ENABLE_BITCODE'] = 'NO'
config.build_settings['CLANG_WARN_DIRECT_OBJC_ISA_USAGE'] = 'NO'
next if config.base_configuration_reference == nil
xcconfig_path = config.base_configuration_reference.real_path
File.open(xcconfig_path, 'a+') do |file|
file.puts "#include \"#{File.realpath(File.join(framework_dir, 'Generated.xcconfig'))}\""
end
end
end
end

Answer 1

Upon Further inspection of the file and the directories, I saw that in fact it is adding two new pods, Flutter and FlutterPluginRegistrant, and I could add them do the PodFile without the script.
