我在项目中将所有内容都更改为9.0,但在很多吊舱中都遇到了相同的错误。
我尝试做很多不同的事情,但是没有任何效果。有谁知道我该如何解决?

对我有用的是@ raffaelli-l-c和@ arhan-reddy-busam答案的组合。
确保您执行以下操作:
MinimumOSVersion
中将ios/Flutter/AppFrameworkInfo.plist
设置为9.0 platform :ios, '9.0'
中的ios/Podfile
的注释ios/Podfile
包含以下安装后脚本: post_install do |installer|
installer.pods_project.targets.each do |target|
flutter_additional_ios_build_settings(target)
target.build_configurations.each do |config|
config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'
end
end
end
在进行生产构建时,以下例程对我有用:
flutter clean \
&& rm ios/Podfile.lock pubspec.lock \
&& rm -rf ios/Pods ios/Runner.xcworkspace \
&& flutter build ios --build-name=1.0.0 --build-number=1 --release --dart-define=MY_APP_ENV=prod

我用这段代码解决了,谢谢! 在PodFile的末尾

这是因为XCode 12仅支持针对iOS目标版本9-14的构建。不幸的是,由flutter设置的默认iOS目标是8。但是,您应该能够使用ios / Runner.xcworkspace文件更改目标XCode。请参阅flutter documentation部分“查看Xcode项目设置”->标题“部署目标:”。
您还可以尝试将flutter更新到1.22 beta,该版本支持iOS 14和XCode 12(如here所述)

要解决此问题,您只需将部署目标更新到 9.0。这可以通过打开 .xcworkspace
文件,在 Xcode 上选择 Pods.xcodeproj
,并将 iOS 部署目标 更新到 9.0 或更高版本来更新如下图
在 Xcode 中打开 ios/Runner.xcworkspace
并更改
除非您导入支持文件,否则您无法在 Xcode 12 上提供对 iOS 8.0 的支持。要默认提供支持,您必须使用 Xcode 11。最好检查在 iOS 8 上使用您的应用的用户数量,并将支持的最低版本更新为 iOS 9 或更高版本。

确保在您的任何 dart 文件中都没有导入 dart.html 包。 当 flutter 尝试安装 pod 时,这在我的情况下导致了问题。

我尝试了很多事情,但似乎为我解决的问题是:
class Solution {
public boolean isSubtree(TreeNode s, TreeNode t) {
/* dfs on s, at each node running a compare tree function for s at that node and
root of t*/
if(s == null || t == null) {
return false;
}
return dfs(s, t);
}
public static boolean dfs(TreeNode s, TreeNode t) {
if(s == null) {
return false;
}
// ==== Corrected below if ====
// apart from s.val == t.val, if isSameTree(s, t) is true at this
// point, return true; otherwise keep doing dfs for rest of the tree s
// other same value node of s can be the answer
if(s.val == t.val && isSameTree(s, t)) {
return true;
}
return dfs(s.left, t) || dfs(s.right, t);
}
public static boolean isSameTree(TreeNode s, TreeNode t) {
if(s == null || t == null) {
return s == t;
}
if(s.val != t.val) {
return false;
}
return isSameTree(s.left, t.left) && isSameTree(s.right, t.right);
}
}

更新到 iOs 14.4 时,path_provider 包似乎与目标 10.0 不兼容。目前 Firebase 软件包需要目标 10.0.0。问题来了,我已经有一个月了。也许 Flutter 团队可以提供帮助。构建 iO 时,出现无法修复的错误,hic hic。

检查 Flutter.podspec 文件,并根据您的要求将版本更改为 9.0 或 10.0
答案 11 :(得分:-2)
尝试做flutter clean
。它会清理xcode项目,因此应该可以解决问题。
