flutter - android Unhandled Exception 上的 Flutter 运行错误：MissingPluginException（未找到方法的实现）

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，我看到调试控制台上的错误我的颤振版本是 1.22，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。但仍然是同样的错误

这是错误列表：

[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)
[ERROR:flutter/lib/ui/ui_dart_state.cc(177)] Unhandled Exception: MissingPluginException(No implementation found for method initialize on channel dexterous.com/flutter/local_notifications)

# 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

# In Android, build-name is used as versionName while build-number used as versionCode.

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

  # 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
  #   - family: Trajan Pro
  #     fonts:
  #       - asset: fonts/TrajanPro.ttf
