构建应用程序时出现 Flutter file_picker 包错误

编程问答 2022-05-10

问题描述

我创建了一个 Flutter 应用程序，其中一部分要求是从存储中选择文件。由于有几个教程使用它，我已经为此选择了 file_picker 3.0.1 包。但是，我在尝试运行我的应用程序时遇到了问题。我什至还没有开始使用这个包。这是我得到的错误

这是我也遇到的另一个错误

The build Failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetifier to solve the incompatibility.

这是 pubspec.yaml 文件

description: A new Flutter project.

# The following line prevents the package from being accidentally published to
# pub.dev using `pub publish`. This is preferred for private packages.
publish_to: 'none' # Remove this line if you wish to publish to pub.dev

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots,like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in Flutter
# build by specifying --build-name and --build-number,respectively.
# In Android,build-name is used as versionName while build-number used as versionCode.

# The following section is specific to Flutter.
Flutter:

  # The following line ensures that the Material Icons font is
  # included with your application,so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

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

  # An image asset can refer to one or more resolution-specific "variants",see
  # https://Flutter.dev/assets-and-images/#resolution-aware.

  # 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
  #       - asset: fonts/TrajanPro_Bold.ttf
