Flutter国际版本冲突

Question

我收到这个错误:

Because my_rents depends on flutter_localizations any from sdk whichdepends on intl 0.17.0-nullsafety.2, intl 0.17.0-nullsafety.2 isrequired. So, because my_rents depends on intl ^0.16.0, versionsolving failed. pub get failed (1; So, because my_rents depends onintl ^0.16.0, version solving failed.)

my_rents 是我的应用程序的名称，它不是一个特定的包

如果不是

intl: ^0.16.1

我有

intl: 0.17.0-nullsafety.2

我得到的错误是

Because firebase_auth >=0.18.0+1 <0.18.1 depends on firebase_auth_web^0.3.0+1 and firebase_auth >=0.18.1 <=0.18.1+1 depends onfirebase_auth_web ^0.3.1, firebase_auth >=0.18.0+1 <=0.18.1+1 requiresfirebase_auth_web ^0.3.0+1. And because firebase_auth >=0.18.1+2<0.18.2 depends on firebase_auth_web ^0.3.1+1, firebase_auth

=0.18.0+1 <0.18.2 requires firebase_auth_web ^0.3.0+1. And because firebase_auth >=0.18.2 <0.18.3 depends on firebase_auth_web ^0.3.1+2and firebase_auth >=0.18.3+1 <0.18.4 depends on firebase_auth_web^0.3.2+1, firebase_auth >=0.18.0+1 <0.18.3-∞ or >=0.18.3+1 <0.18.4-∞requires firebase_auth_web ^0.3.0+1. And because firebase_auth=0.18.3 <=0.18.3 depends on firebase_auth_web ^0.3.2 and firebase_auth >=0.18.4 <=0.18.4 depends on firebase_auth_web ^0.3.2+2,firebase_auth >=0.18.0+1 <=0.18.4 requires firebase_auth_web ^0.3.0+1.And because firebase_auth ^0.18.4+1 depends on firebase_auth_web^0.3.2+3 which depends on intl ^0.16.1, firebase_auth ^0.18.0+1requires intl ^0.16.1. So, because my_rents depends on bothfirebase_auth ^0.18.0+1 and intl 0.17.0-nullsafety.2, version solvingfailed. pub get failed (1; So, because my_rents depends on bothfirebase_auth ^0.18.0+1 and intl 0.17.0-nullsafety.2, version solvingfailed.)

Answer 1

dart 和 flutter 团队正在过渡到 null-safety特征。它仍处于测试阶段(这就是为什么您只在测试 channel 中收到此错误的原因)。并非每个包都已升级到空安全。您可以通过以下任一方式解决此问题:

• 要求包的开发者升级到空安全
• 使用未启用 null-safety 的 flutter 版本
• 使用启用 null-sefty 的测试版软件包 Check also this issue

原始答案:Pubspec.yaml resolving version failed in master channel but works in stable channel in Flutter

目前最简单的解决方案是:

flutter channel stable

flutter upgrade
