无法找到“Frameworks/App.framework/flutter_assets”的资产路径

Question

我正在尝试在模拟器（ iPhone 8 ）上运行我的 flutter 应用程序，但是当应用程序午餐时，我得到的只是一个空白的白屏。像这样：

终端输出为：

Running pod install...                                             40.0s

我正在使用 flutter 的稳定版本1.12.13+hotfix.9，这个问题只出现在 ios 构建中。

我该如何解决这个问题？

Answer 1

我刚刚设法解决了这个问题。我刚刚遵循了建议https://github.com/flutter/flutter/issues/29974并添加了 “$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh”嵌入 到运行脚本 运行脚本 重建App.framework文件夹后有已添加到构建目录，问题已经消失。希望这会帮助别人。

您可以按照https://flutter.dev/docs/development/ios-project-migration 中的说明进行操作

特别是构建阶段：

/bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" embed
/bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" thin
