在构建Flutter到IOS时找不到BoringSSLGRPC.modulemap

我现在正在将此应用程序与 firebase 一起使用，当我尝试在 xcode 中构建时，它会引发此错误：

未找到模块映射文件“/--mypath--/ios/Pods/Headers/Private/openssl_grpc/BoringSSL-GRPC.modulemap”

上面是我的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


我已经尝试use_frameworks!并退出use_modular_headers!但仍然显示错误。我坚持下去，欢迎任何帮助

更新

我读到这可能是 firebase 依赖版本的问题。这是我的pubspec。有什么问题吗？
