Flutter：无法删除包含在 ios 应用程序中的自定义插件

Question

我为 windows 编写了一个自定义的 flutter 插件，目前运行良好。但出于某种原因，当我尝试在 iphone 模拟器上运行时，flutter 一直将插件包含在 ios 构建中。这会导致错误，因为插件没有 ios 实现。在 Android 上一切正常。

这是插件 pubspec.yaml:

name: fbfunctions
description: A new flutter plugin project.

environment:
  sdk: ">=2.7.0 <3.0.0"
  flutter: ">=1.10.0"

dependencies:
  flutter:
    sdk: flutter

flutter:
  plugin:
    platforms:
      windows:
        pluginClass: FbfunctionsPlugin

这是我在 ios 模拟器上尝试运行时遇到的错误：

如何防止 flutter 尝试将插件包含在 ios 构建中？

Answer 1

你不能；当前 Flutter expects every plugin to have an iOS podspec. Until that is resolved, the workaround is to include a dummy ios/your_plugin_name.podspec, as you can see in federated flutter/plugins plugins.

除了 podspec 之外，您不需要文件夹中的任何内容，一旦问题得到解决，您就可以将其删除。
