firebase - BoringSSL-GRPC.modulemap not found when building flutter to IOS

Question

I'm using this app with firebase now, and when I try to build in xcode, it throws this error:

module map file '/--mypath--/ios/Pods/Headers/Private/openssl_grpc/BoringSSL-GRPC.modulemap' not found

Above is my podfile

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

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

post_install do |pi|
  pi.pods_project.targets.each do |t|
    t.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = "10.0"
    end  
  end
end

I already tried use_frameworks! and dropping out use_modular_headers! but still showing the error. I'm stuck on it and any help will be welcome

Update I read that it can be a problem of firebase dependencies versions. This is my pubspec. There are any problem with it?

Use use_frameworks! :linkage => :static instead of use_modular_headers!
