我正在研究一个项目，在与队友合并代码之前，包 sms_autofill 可以正常运行，但是在代码合并之后，我已经运行了 flutter clean ，但仍然显示两个错误，如下所示：
Unhandled Exception: MissingPluginException(No implementation found for method listenForCode on channel sms_autofill)
和

# To add assets to your application, add an assets section, like this:
assets:
- .env
- assets/images/

# An image asset can refer to one or more resolution-specific "variants", see

# For details regarding adding assets from package dependencies, see
# https://flutter.dev/assets-and-images/#from-packages
# To add custom fonts to your application, add a fonts section here,
# in this "flutter" section. Each entry in this list should have a
# "family" key with the font family name, and a "fonts" key with a
# list giving the asset and other descriptors for the font. For
# example:
# fonts:
# - family: Schyler
# fonts:
# - asset: fonts/Schyler-Regular.ttf
# - asset: fonts/Schyler-Italic.ttf
# style: italic

我不知道这是怎么回事，我曾尝试在互联网上搜索，但似乎没有与此相关的解决方案。 enter code here
答案 0 :(得分：0)
最后，我知道问题出在哪里。
软件包sms_autofill本身不是问题的原因，问题在于软件包flutter_facebook_login已安装且未使用。删除或正确使用它可以解决问题。
