# 进入my_project
cd my_project
# 创建module项目
flutter create --template module flutter_module
# 进入创建的module项目
cd flutter_module
# 删除默认文件，创建软连接指向flutter_app
rm -rf lib
ln -s ../flutter_app/lib lib
rm pubspec.yaml
ln -s ../flutter_app/pubspec.yaml pubspec.yaml
rm -rf assets
ln -s ../flutter_app/assets assets
rm analysis_options.yaml
ln -s ../flutter_app/analysis_options.yaml analysis_options.yaml
# 由于flutter_app里引入了rust库，所以这里需要给生成的rust项目也进行软连接管理
rm -rf rust_builder
ln -s ../openchat_client/rust_builder rust_builder
# 执行编译
flutter clean
flutter pub get

配置flutter_rust_bridge的生成项目 xxx/rust_builder/cargokit/build_pod.sh xxx/rust_builder/cargokit/run_build_tool.sh 都在最顶部配置flutter位置

#!/usr/bin/env bash

set -e
if [ -z "$FLUTTER_ROOT" ]; then
  # which flutter的结果 /Users/xxx/flutter/bin/flutter
  FLUTTER_ROOT="/Users/xxx/flutter"  # fallback 路径
fi
export PATH="$FLUTTER_ROOT/bin:$FLUTTER_ROOT/bin/cache/dart-sdk/bin:$PATH"
.

在swift项目的Podfile里引入flutter_module

# Uncomment the next line to define a global platform for your project
platform :ios, '12.0'
source 'https://github.com/CocoaPods/Specs.git'

# flutter配置1找到当前Podfile相对于module的相对路径
flutter_application_path = '../flutter_module'
load File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb')

abstract_target 'abstract_pod' do  #这里的abstract_pod在实际targets中不存在，是虚拟
   inhibit_all_warnings!
   use_frameworks!
   
   pod 'Alamofire', '~> 4.9.1'
   pod 'SnapKit', '~> 5.0.1'
   pod 'Kingfisher', '~> 5.14.1'

  target 'HelloWorld' do
    # flutter配置2（必须卸载target里，如果写在abstract_target里会报错 [!] Invalid `Podfile` file: [!] Script phases cannot be added to abstract targets..）
    # install_all_flutter_pods(flutter_application_path)
  end

end

post_install do |installer|
    # flutter配置3
    flutter_post_install(installer) if defined?(flutter_post_install)
    installer.pods_project.targets.each do |target|
      if target.name == 'BoringSSL-GRPC'
        # 解决BoringSSL-GRPC报错问题
        target.source_build_phase.files.each do |file|
          if file.settings && file.settings['COMPILER_FLAGS']
            flags = file.settings['COMPILER_FLAGS'].split
            flags.reject! { |flag| flag == '-GCC_WARN_INHIBIT_ALL_WARNINGS' }
            file.settings['COMPILER_FLAGS'] = flags.join(' ')
          end
        end
      end
      target.build_configurations.each do |config|
        # 解决M系列芯片报错问题
        config.build_settings['ONLY_ACTIVE_ARCH'] = 'NO'
        config.build_settings['LD_NO_PIE'] = 'NO'
        config.build_settings['CODE_SIGNING_ALLOWED'] = 'NO'
        config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0'
      end
    end
end

接入失败，直接在flutter_module里的pubspec.yaml里引入

name: flutter_module

environment:
  sdk: ^3.7.2

dependencies:
  flutter:

flutter:
  
  module:
    androidX: true
