iPhone 上的 flutter 运行模拟器卡在 'Xcode build done' 上。（它运行在 android 模拟器中很好）

Question

问题

您好，我在 iPhone 模拟器上运行我的 Flutter 应用程序时遇到困难。它停留在 'Xcode build done'。顺便说一句，它在 Android 模拟器上运行良好。

这是我第一次在这里提问，所以如果需要更多信息或有不当之处，请告诉我。任何形式的帮助（或评论）将不胜感激。谢谢。

尝试手动启动应用程序的视频： https://user-images.githubusercontent.com/60031762/141050073-648a9893-0e33-425e-9c9d-24966bf1be39.mov

p.s。我还在 flutter github 上开了一个问题：https://github.com/flutter/flutter/issues/93361

以下是详细信息：重现步骤和日志。

重现步骤

OS: macOS Big Sur 11.6, 连接到我的 iPhone 11 pro(iOS 15.1).[=28= 的 USB 网络(热点) ]

克隆 https://github.com/kws1207/friendship/tree/main/where_to_eat 并打开项目。
运行模拟器，打开iPhone12 Pro Max，iOS14.4.
执行flutter run.
Select模拟器在2中打开

预期结果：

Launching lib/main.dart on iPhone 12 Pro Max in debug mode...
Running Xcode build...                                                  
 └─Compiling, linking and signing...                         8.3s
Xcode build done.                                           268.6s
Installing and launching...
Flutter run key commands.
r Hot reload. 
R Hot restart.
h List all available interactive commands.
d Detach (terminate "flutter run" but leave application running).
c Clear the screen
q Quit (terminate the application on the device).

Running with unsound null safety
For more information see

实际结果：

Launching lib/main.dart on iPhone 12 Pro Max in debug mode...
Running Xcode build...                                                  
 └─Compiling, linking and signing...                         8.3s
Xcode build done.                                           268.6s
(it stucks here)

尝试从 Xcode.

来自 Xcode 的输出：

Answer 1

请检查list_screen中的错误，行号548和690。删除Podfile.lock。运行扑干净。然后运行flutter run。使用项目根目录中的 cd ios 导航到终端中的 ios 文件夹。运行pod install。现在，一旦安装了 pods，打开 xcode 中的 xcworkspace 文件，您可能会看到一条警告，要求您升级 ios 的最低版本。允许它升级设置。现在 select 来自 xcode 的模拟器并点击播放。一旦它在 xcode 播放良好，您应该也可以直接从 Android 工作室运行它。

Answer 2

您需要将 firebase 配置初始化到 appdelegate.swift 文件中。

import UIKit
import Flutter
import Firebase

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    GeneratedPluginRegistrant.register(with: self)
    
    if FirebaseApp.app() == nil {
        FirebaseApp.configure()
    }
    
   // FirebaseApp.configure()
    
   return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

Answer 3

请在 Xcode 的 buildSettings 中为 iOS 应用尝试此操作添加新用户定义

具有值 --no-sound-null-safety

的键 EXTRA_FRONT_END_OPTIONS

并清除派生数据并再次重建它，然后运行它。

问题是我删除了 'Copy Bundle Resources' 中的所有组件。我在上面添加了 Main.storyboard，应用程序运行正常。
