在 android 设备和模拟器中运行，但 iPhone 模拟器出现问题

Question

我正在尝试在 iPhone 12 pro max 模拟器中运行我的颤振应用程序。它在 android 设备和模拟器中成功运行，但我在 ios 平台上运行时遇到问题。颤动中的 Connectivity 5.0.0 似乎有问题，但我在 PodFile 中手动添加如下：

# Uncomment the next line to define a global platform for your project
platform :ios, '12.1'

target 'glamme' do
  # Comment the next line if you don't want to use dynamic frameworks
  use_frameworks!

  # Pods for glamme
  pod "Firebase"
  pod "Connectivity"    

  target 'glammeTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'glammeUITests' do
    # Pods for testing
  end

end

target 'Runner' do
  # Comment the next line if you don't want to use dynamic frameworks
  use_frameworks!

  # Pods for Runner
  pod "Firebase"
  pod "Connectivity"

end

这是我尝试在 iPhone 12 pro max 模拟器中运行时的输出

Answer 1

通常解决方法是：删除 podfile、flutter clean、flutter pub get 和 flutter build ios。确保平台很重要：pod 文件中的 iOS 版本也与 Xcode 中的部署信息匹配。
