Flutter 更新到颤振2.0时出现颤振版本问题

更新后，我的所有类都出现错误。 我也试着把颤振清理干净。当我运行flatterpub-get命令时，我得到以下错误

Because no versions of intl_utils match >1.8.0 <1.9.0 and intl_utils ^1.9.0 depends on intl_translation 0.17.10+1, intl_utils >1.8.0 <2.0.0 requires intl_translation 0.17.10+1.
And because intl_utils 1.8.0 depends on intl_translation 0.17.10 which depends on intl >=0.15.3 <0.17.0, intl_utils ^1.8.0 requires intl >=0.15.3 <0.17.0 or intl_translation 0.17.10.
And because intl_translation 0.17.10 depends on intl >=0.15.3 <0.17.0 and every version of flutter_localizations from sdk depends on intl 0.17.0, intl_utils ^1.8.0 is incompatible with flutter_localizations from sdk.
So, because markets depends on both flutter_localizations any from sdk and intl_utils ^1.8.0, version solving failed.
pub get failed (1; So, because markets depends on both flutter_localizations any from sdk and intl_utils ^1.8.0, version solving failed.)

因为没有任何版本的intl_utils匹配>1.8.0 1.8.0=0.15.3=0.15.3=0.15.3是，请尝试降低颤振版本。我也有同样的问题

flutter downgrade 1.22.6

错误很明显。并不是所有的插件都有更新来使用颤振2。这就是为什么人们会说，在升级现有项目中的核心/插件之前检查兼容性。我应该如何解决这些错误？降级？
