报错图片
背景
flutter 开发的 apple app 需要发布新版本,但是最后一哆嗦碰到个报错,这个小问题卡住了我一天,之间的埪就不说了,直接说我是怎么解决的,满满干货
思路
这个报错 涉及到 flutter_barcode_scanner; 所以一开始我一直在更改这个插件的版本上下手,最终失败告终,当我绝望之时,发现这个flutter_barcode_scanner 插件官网的一句话
If your existing ios code is Objective-C then you need to do following.
- Create a new flutter project with same name at different location (Don't forget to check Include swift support for iOS code while creating)
- Just copy newly created
/ios
folder from project and replace with existing/ios
.- Open ios project in Xcode and set minimum deployment target to 12 and set Swift version to 5.
- Run pod install in
/ios
Note: If you did any changes in ios part before, you might need to make these configuration again
总的来说就是我用到的插件对应的苹果版本有所改变,这里是要求最低 minimum deployment target 12
详细解决步骤
首先xcode 打开当前的 flutter 项目 ios 包的Runner.xcworkspace 文件(双击即可直接打开到 xcode)

第一步:直接看图

第二步:

第三步:
关于此插件的版本限制应该就解决完了,但是还没结束,更改完上述内容保存或者直接退出 xcode
第四步:
随便打开一个你常用的编译器,打开 flutter 完整项目
删除pubspec.lock文件,依次执行
flutter clean
flutter pub cache repair
flutter pub get
flutter build ios
第五步:
等编译成功,再次把项目从 xcode 打开,运行! 你会发现,解决❗️
