Flutter 2.5.1 - 无法为模拟器构建应用程序

Question

我将我的项目从 Flutter 1 迁移到 2.5.1，并反驳了这个错误

结果：

我所有的 package/plugins 都更新到 nullsafety 版本，我也确实删除了 ios 文件夹并使用 flutter create . 创建了一个新文件夹，我仍然得到相同的结果。

Answer 1

从 pubspec.yaml 和运行 flutter pub get 中删除插件。

然后再次添加插件运行 flutter pub get.

或

flutter pub cache repair

Answer 2

请尝试以下步骤：

如果你有英特尔芯片

颤抖干净
将pubspec.yml文件中的所有依赖项更新为最新版本并执行'get pub'
转到您的 Podfile 并取消注释 #platform :ios, '9.0' 然后将版本更改为 10 platform :ios, '10.0'
通过终端转到 ios 文件夹并执行 'pod repo update'
'pod update' 或 'pod install'

如果你有M1芯片

颤抖干净
将pubspec.yml文件中的所有依赖项更新为最新版本并执行'get pub'
转到您的 Podfile 并取消注释 #platform :ios, '9.0' 然后将版本更改为 10 platform :ios, '10.0'
通过终端转到 ios 文件夹并执行 'arch -x86_64 pod repo update'
'arch -x86_64 pod update' 或 'arch -x86_64 pod install'

Answer 3

自从您迁移到 Flutter 2.0（空安全）后，出现此错误的原因有很多。

您重新创建了整个 ios and/or android 这将生成新的代码（或语法）和文件，这可能会导致像您所面临的错误.

对于计划迁移的任何人，请始终在 ios and/or android 文件夹中分别保留内部配置的备份文件。

不要只是放下你的 `iOS` 和 `android` 文件夹！

您需要手动重新配置这些文件夹下的文件。如果您使用的是 Firebase 包，则可以在 Podfile 中的 target 'Runner' do:

子句内添加这些行

# add the Firebase pod for Google Analytics
# or pod ‘Firebase/AnalyticsWithoutAdIdSupport’
# for Analytics without IDFA collection capability
# add pods for any other desired Firebase products
# https://firebase.google.com/docs/ios/setup#available-pods
  pod 'Firebase/Analytics'
  pod 'Firebase/DynamicLinks'

遵循一些提示here

之后，确保配置回其他应用的元数据，如 AppBundleName 和 info.plist

中的一些权限

另一件事

（可能是可选的） 如果您要检查 pubspec.yaml，您需要为新的 linting 选项添加一个新行。注意间距。

dev_dependencies:
  flutter_test:
    sdk: flutter
  flutter_lints: ^1.0.0

那就按照 99% Whosebug 用户对这件事总是说的去做:)

delete pubspec.lock

delete pods folder

delete Podfile.lock

flutter pub cache repair

flutter clean

flutter pub get
