来自 sdk 的 flutter_test 与 tiled >=0.4.0 不兼容。添加火焰时：^0.24.0 依赖项答案

【问题标题】：flutter_test from sdk is incompatible with tiled >=0.4.0. when adding flame: ^0.24.0 dependencies来自 sdk 的 flutter_test 与 tiled >=0.4.0 不兼容。添加火焰时：^0.24.0 依赖项
【发布时间】：2020-10-27 18:47:26
【问题描述】：

我在 pubspec.yaml 文件中添加了火焰：^0.24.0 依赖项，但我不知道为什么会出现此错误：

C:\flutter\flutter\flutter\bin\flutter.bat --no-color packages get 在 boxgame 中运行“flutter pub get”...
因为来自 sdk 的 flutter_test 的每个版本都依赖于 xml 3.5.0 并且 tiled >=0.4.0 依赖于 xml ^4.2.0，所以来自 sdk 的 flutter_test 与 tiled >=0.4.0 不兼容。

并且由于火焰 >=0.24.0 依赖于 tiled ^0.6.0，因此来自 sdk 的 flutter_test 与火焰 >=0.24.0 不兼容。

所以，因为 boxgame 依赖于 sdk 中的 flame ^0.24.0 和 flutter_test any，所以版本解析失败。 pub get failed (1; 所以，因为 boxgame 依赖于来自 sdk 的火焰 ^0.24.0 和 flutter_test any，版本求解失败。) 进程以退出代码 1 结束

我的 pubspec.yaml 的代码：

name: boxgame
description: A new Flutter application.

# 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.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.
# Read more about iOS versioning at
# https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html
version: 1.0.0+1

environment:
  sdk: ">=2.1.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter
  flame: ^0.24.0


  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2

dev_dependencies:
  flutter_test:
    sdk: flutter


# For information on the generic Dart part of this file, see the
# following page: https://dart.dev/tools/pub/pubspec

# 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/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
  #         weight: 700

【解决方案1】：

我的项目依赖项有类似的问题，运行它解决了我的问题。

dart pub upgrade --null-safety

它验证和检查依赖项的兼容性并相应地更新它们，而不是仅仅显示不兼容错误

【讨论】：

请描述一下，为什么这应该解决问题，以提供一种方式来解决一些问题，而不是这样做代码。它将帮助未来的读者自己找到解决方案
@astentx 抱歉，这是我第一次回答任何人的问题。我尝试尽我所知对其进行更新。

【解决方案2】：

如果您不使用“flutter_test”依赖项，可以尝试删除它。

dev_dependencies:
  flutter_test:
    sdk: flutter

或者使用稍旧的'flame'版本

  flame: ^0.22.1

这取决于与 'flutter_test' 相同版本的 'tiled'

【讨论】：

我只是添加了火焰：没有别的，它起作用了......谢谢你的回答
