xcode - 未能找到 "Frameworks/App.framework/flutter_assets"的 Assets 路径

Question

我正在尝试在模拟器( iPhone 8 )上运行我的 flutter 应用程序，但是当应用程序吃午饭时，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 ，并且此问题仅出现在 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
“$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh”嵌入
运行脚本
Run script
重建后 App.framework 文件夹已添加到 build 目录，问题消失了。
希望这会帮助别人。
