【问题描述】：

我的代码在 ios 上运行良好。但是android我犯了一些错误。我该如何解决？应用程序在 ios 上运行良好。但是当我尝试在 android 上运行时，我在调试控制台上看到了错误 我的颤振版本是 1.22 并且颤振医生给出任何错误。 我尝试清理并从设备中删除旧版本。但还是一样的错误

这里是错误列表：

[ERROR:flutter/lib/ui/ui_dart_state.cc(177)] Unhandled Exception: MissingPluginException(No implementation found for method getApplicationSupportDirectory on channel
plugins.flutter.io/path_provider)
[ERROR:flutter/lib/ui/ui_dart_state.cc(177)] Unhandled Exception: MissingPluginException(No implementation found for method configure on channel plugins.flutter.io/firebase_messaging)

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43

# Both the version and the builder number may be overridden in flutter

  # To add assets to your application, add an assets section, like this:

  # 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

【参考方案1】：

这是因为您安装了一个新插件，从设备上卸载该应用并再次运行它。

【讨论】：

没有。不是关于新插件安装。我尝试 flutter clean ，然后从设备中删除。但同样的错误

应用程序运行时。应用程序恢复运行，但我无法使用此方法
