我正在做一个flutter项目,我不是第一个开发它的人。在运行pub get
之后,我遇到了大量的错误:
Because xdg_directories >=0.1.2 <0.2.0-nullsafety.0 depends on process >=3.0.12 <5.0.0 and xdg_directories <0.1.2 depends on process ^3.0.12, xdg_directories <0.2.0-nullsafety.0 requires process >=3.0.12 <5.0.0.
(1) So, because path_provider_linux <0.2.0-nullsafety depends on xdg_directories ^0.1.0, path_provider_linux <0.2.0-nullsafety requires process >=3.0.12 <5.0.0.
Because process >=4.0.0-nullsafety.1 <4.0.0-nullsafety.4 requires SDK version >=2.10.0-0.0 <2.12.0 and process >=4.0.0-nullsafety.4 <4.0.0 depends on platform ^3.0.0-nullsafety.4, process >=4.0.0-nullsafety.1 <4.0.0 requires platform ^3.0.0-nullsafety.4.
And because process >=3.0.12 <4.0.0-nullsafety.1 depends on intl >=0.14.0 <0.17.0 and process >=4.0.0 depends on platform ^3.0.0, process >=3.0.12 requires platform ^3.0.0-nullsafety.4 or intl >=0.14.0 <0.17.0.
(2) So, because path_provider_linux <0.2.0-nullsafety requires process >=3.0.12 <5.0.0 (1), path_provider_linux <0.2.0-nullsafety requires platform ^3.0.0-nullsafety.4 or intl >=0.14.0 <0.17.0.
Because shared_preferences_linux <=0.0.2 depends on path_provider ^1.6.11 and shared_preferences_linux >=0.0.4-nullsafety <2.0.0 depends on shared_preferences_platform_interface ^2.0.0-nullsafety, shared_preferences_linux <0.0.2+1 or >=0.0.4-nullsafety <2.0.0-∞ requires path_provider ^1.6.11 or shared_preferences_platform_interface ^2.0.0-nullsafety.
And because shared_preferences_linux >=0.0.2+1 <0.0.4-nullsafety depends on path_provider_linux ^0.0.1 and path_provider >=1.6.10 <2.0.0-nullsafety depends on path_provider_linux ^0.0.1, shared_preferences_linux <2.0.0 requires shared_preferences_platform_interface ^2.0.0-nullsafety or path_provider_linux ^0.0.1.
And because path_provider_linux <0.2.0-nullsafety requires platform ^3.0.0-nullsafety.4 or intl >=0.14.0 <0.17.0 (2), shared_preferences_linux <2.0.0 requires platform ^3.0.0-nullsafety.4 or intl >=0.14.0 <0.17.0 or shared_preferences_platform_interface ^2.0.0-nullsafety.
And because every version of flutter_localizations from sdk depends on intl 0.17.0 and shared_preferences >=0.5.8 <2.0.0-nullsafety depends on shared_preferences_linux ^0.0.2, if flutter_localizations any from sdk and shared_preferences >=0.5.8 <2.0.0-nullsafety then platform ^3.0.0-nullsafety.4 or shared_preferences_platform_interface ^2.0.0-nullsafety.
And because shared_preferences >=0.5.4+8 <2.0.0-nullsafety depends on shared_preferences_platform_interface ^1.0.0 and every version of localize_and_translate depends on flutter_localizations any from sdk, if shared_preferences >=0.5.8 <2.0.0-nullsafety and localize_and_translate any then platform ^3.0.0-nullsafety.4.
And because localize_and_translate ^3.0.3 depends on shared_preferences ^0.5.12+4 and firebase_messaging >=0.2.0 <7.0.2 depends on platform ^2.0.0, localize_and_translate ^3.0.3 is incompatible with firebase_messaging >=0.2.0 <7.0.2.
So, because educationtqnia depends on both firebase_messaging ^6.0.13 and localize_and_translate ^3.0.3, version solving failed.
pub get failed (1; So, because educationtqnia depends on both firebase_messaging ^6.0.13 and localize_and_translate ^3.0.3, version solving failed.)
Process finished with exit code 1

# For information on the generic Dart part of this file, see the

# 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:
- langs/ar.json
- langs/en.json
- assets/
# 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: Cairo
fonts:
- asset: assets/fonts/Cairo-Black.ttf
- asset: assets/fonts/Cairo-Bold.ttf
- asset: assets/fonts/Cairo-ExtraLight.ttf
- asset: assets/fonts/Cairo-Light.ttf
- asset: assets/fonts/Cairo-Regular.ttf
- asset: assets/fonts/Cairo-SemiBold.ttf

# For details regarding fonts from package dependencies,

我试着降级flutter SDK,在不同的频道之间切换,并运行更改库的版本来解决这个问题,但都没有效果。有什么办法可以解决这个问题吗?谢谢。

当Flutter或一些插件已经更新时,这个问题非常常见。我唯一能做的就是更新所有的东西,包括flutter和插件到他们的最新版本,如果一个因为没有维护而不兼容,试着把它换成另一个。

添加到Miguels答案-如果需要在最新的flutter版本上可用,并与其他库兼容,您可以在相关库的GitHub页面上提交问题。
