体系结构x86_64抖动的未定义符号 [英] Undefined symbols for architecture x86_64 flutter

问题描述

我正在处理应用程序混乱问题.Android工作正常，但在iOS中没有.我需要一些帮助才能在ios mobile上运行它.我正在使用lib: google_maps_flutter:^ 0.5.27 + 3 和 firebase_ml_vision:^ 0.9.3 + 8 .Xcode 11.4.1和Mac os Catalina 10.15.4.有人知道如何解决这个问题.我还没找到.

I'm working in an app flutter. Android working fine but in ios no. I need some help to run this on ios mobile. I'm using lib: google_maps_flutter: ^0.5.27+3 and firebase_ml_vision: ^0.9.3+8. Xcode 11.4.1 and Mac os Catalina 10.15.4. Someone knows how to solve this. I didn't found yet.

推荐答案

错误可能出在某些XCode项目文件上，请尝试:

Probably the error is on some of the XCode project files, try:

1. 备份项目.

2. 运行此命令

1. Make a backup of your project.

2. Run this command

颤振清洁&&\rm ios/Podfile ios/Podfile.lock pubspec.lock&&\rm -rf ios/Pods ios/Runner.xcworkspace&&\扑动

flutter clean && \ rm ios/Podfile ios/Podfile.lock pubspec.lock && \ rm -rf ios/Pods ios/Runner.xcworkspace && \ flutter run
