flutter问题

问题一

1.报错：

Flutter ios/Flutter/Debug.xcconfig: unable to open file (in target "Runner" in project "Runner")

2.解决：

cd 项目目录

flutter clean

flutter create --org solanddriver .

运行Xcode

问题二

1.Cannot run with sound null safety, because the following dependencies

解决方案：

可以直接在命令行中执行

flutter run --no-sound-null-safety

也可以到Android studio中去设置运行配置

首先打开Edit Configurations 页面

然后在Additional run args 这行键入一下命令

--no-sound-null-safety

如图所示

然后点击OK，再次重新运行就可以了

2.building for iOS Simulator, but linking in object file built for iOS, file for architecture arm64

podfile文件末尾添加以下脚本：然后执行pod install 命令。

post_install do |installer| installer.pods_project.targets.each do |target| target.build_configurations.each do |config| config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64" end end end
