带有静态ios框架和cloud_firestore包的Flutter包

Question

我正在开发 Flutter 包，它依赖于静态 ios 框架，如 podspec 中的

spec.dependency 'static-pod', '~> 1.0.0'

当我在项目中使用我的包时，一切正常。但是当我尝试添加

use_modular_headers!

包时，我遇到了这个问题：cloud_firestore

如果我尝试添加 

Error (Xcode): module map file '/Users/me/projects/flutter-project/ios/Pods/Headers/Private/openssl_grpc/BoringSSL-GRPC.modulemap' not found

我将收到下一个错误：

use_frameworks! :linkage => :static

在我的 ios/Classes 目录下一个结构：

MyPlugin.h

• 我的插件.m
• SwiftMyPlugin.swift
以及完整的插件 podspec 文件：

Lexical or Preprocessor Issue (Xcode): 'plugin-Swift.h' file not found
/Users/me/.pub-cache/hosted/pub.dev/plugin-1.4.7/ios/Classes/MyPlugin.m:1:8

Answer 1

require 'yaml'

pubspec = YAML.load_file(File.join('..', 'pubspec.yaml'))

Pod::Spec.new do |spec|
  spec.name             = pubspec['name']
  spec.version          = pubspec['version']
  spec.summary          = 'My Flutter plugin.'
  spec.description      = pubspec['description']
  spec.homepage         = pubspec['homepage']
  spec.license          = { :type => 'MIT License', :file => '../LICENSE' }
  spec.author           = '[email protected]'
  spec.source           = { :path => '.' }

  spec.source_files = 'Classes/**/*'
  spec.public_header_files = 'Classes/**/*.h'

  spec.platform = :ios, '14.0'
  spec.dependency 'Flutter'
  spec.dependency 'static-pod', '~> 1.0.0'

  # Flutter.framework does not contain a i386 slice.
  spec.pod_target_xcconfig = { 'DEFINES_MODULE' => 'YES', 'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'i386' }
  spec.swift_version = '5.0'
end

不适用于 Firestore。详细信息请参见

https://github.com/firebase/firebase-ios-sdk/issues/3816

。 Firestore 以及所有最新的 Firebase 产品版本应与

use_modular_headers!

或

use_frameworks!

集成。
