flutter_launcher_icons 不工作（应用程序启动器图标 broken/crashed）

Question

我正在努力使用 flutter_launcher_icons 包在我的 iPhone 模拟器（iOS 14.4）上更改 App Launcher 图标。

在我的 pubspec.yaml:

dev_dependencies:
  flutter_test:
    sdk: flutter
  flutter_launcher_icons: ^0.9.2

flutter_icons:
  #image_path_android: "assets/icon.png"
  image_path: "assets/icon.png"
  android: false
  ios: true

在 VScode 终端上（在我的项目根目录中）：

> flutter pub run flutter_launcher_icons:main
  ════════════════════════════════════════════
     FLUTTER LAUNCHER ICONS (v0.9.1)                               
  ════════════════════════════════════════════
  
• Overwriting default iOS launcher icon with new icon

但在模拟器中，应用程序启动器图标坏了（'Runner' 是应用程序）：

在~/ios/Runner/Assets.xcassets/AppIcon.appiconset/中，我可以看到图像文件已正确更改。

我该如何解决这个问题？也许这不是包问题，而是 iOS 构建问题??

Answer 1

使用 https://appicon.co 等在线工具并替换 AppIcon.appiconset 文件夹。

Answer 2

以下是您的应用未显示应用图标的部分原因：

您在他们提到的文档中为 flutter 图标启动器提供了错误的图像：检查应用程序图标文件的尺寸是否为 1024x1024 像素。
检查 AppIcon.appiconset 是否正确生成并清除 Xcode 图像资产中的显示。
检查项目应用程序图标路径是否在项目常规设置中正确设置。

4.Check 正在重启模拟器。有时这也能解决问题。

Answer 3

已解决。问题是我不小心删除了 'Copy Bundle Resources'.
