1、The Swift pod `DKPhotoGallery` depends upon `SDWebImage`, which does not define modules. To opt into those targets generating module maps (which is necessary to import them from Swift when building as static libraries), you may set `use_modular_headers!`
解决：在podfile文件中，找到【target 'Runner' do】这一行，换行加入【use_frameworks!】，注意不要带中括号【】。
2、`speech_to_text` does not specify a Swift version and none of the targets (`Runner`) integrating it have the `SWIFT_VERSION` attribute set. Please contact the author or set the `SWIFT_VERSION` attribute in at least one of the targets that integrate this pod.
解决：在podfile文件中，加入【ENV['SWIFT_VERSION'] = '5.0'】，同时在xcode工程中的Build Setting设置中，加入字段key：SWIFT_VERSION，值：5.0
3、Unexpected duplicate tasks
解决：在Xcode项目中找到Build Phases，在右上角搜索报错的具体文件名，然后去除重复的文件引用即可。
4、Flutter项目运行报错：[!] CocoaPods did not set the base configuration of your project because your project already has a custom config set. In order for CocoaPods integration to work at all, please either set the base configurations of the target `Runner` to `Target Support Files/Pods-Runner/Pods-Runner.debug.xcconfig` or include the `Target Support Files/Pods-Runner/Pods-Runner.debug.xcconfig` in your build configuration (`Flutter/Debug.xcconfig`).
解决：在Xcode工程下，Flutter目录下，在Debug.xcconfig中添加：
#include? "Pods/Targets Support Files/Pods-Runner/PodsRunner.debug.exconfig"在Release.xcconfig中添加：
#include? "Pods/Targets Support Files/Pods-Runner/PodsRunner.release.exconfig"
#include? "Pods/Targets Support Files/Pods-Runner/Pods-Runner.profile.exconfig"5、Flutter项目运行报错：Unable to load contents of file list: '/Target Support Files/Pods-Runner/Pods-Runner-frameworks-Debug-input-files.xcfilelist'
解决：在flutter项目，先在pubspec.yaml文件中添加一个三方库，然后执行 【pub get】命令，之后在ios工程中会自动生成Podfile文件，切记不要使用pod命令自动创建，因为flutter工程默认创建的跟自己创建的内容不一样，就会导致以上问题。
6、The code signature version is no longer supported
解决
方式一：
Building Setting-- OTHER_CODE_SIGN_FLAGS
在你的调试模式下 添加：
–generate-entitlement-der
方式二：
查看所引用的库是否缺少，比如系统库libc++.tbb、libz.tbd
7、[!] No podspec found for `amap_flutter_location` in `../dzt/dzt/.ios/
解决：删除/Users/xxx/.pub-cache文件夹，然后在flutter工程中，重新拉取插件，flutter pub get，之后进入iOS工程中，使用命令 pod install 拉取三方依赖库即可。
