问题：

未处理的异常：MissingPluginException（在sms_autofill频道上找不到方法listenForCode的实现）

我正在做一个项目，在与我的队友合并代码之前，package sms_autofill运行正常，但在代码合并后，我已经运行了Flatter clean，但它仍然显示两个错误，如下所示：

Unhandled Exception: MissingPluginException(No implementation found for method listenForCode on channel sms_autofill)

和

Unhandled Exception: MissingPluginException(No implementation found for method getAppSignature on channel sms_autofill)

我不知道它有什么问题，我已经尝试在互联网上搜索，似乎没有与之相关的解决方案。在此处输入代码

终于知道问题出在哪里了。

软件包sms_autofill本身不是问题的原因，问题在于软件包flatter_facebook_login已安装且未使用。移除或正确使用它将解决问题。

未处理的异常：MissingPluginException（在sms_autofill频道上找不到方法listenForCode的实现）
