flutter - dart migrate 在我自己的代码文件中给出错误

问题描述

当我运行“dart migrate”以启用空安全时，它会给出以下输出。


Before migrating your package, we recommend ensuring that every library it
imports (either directly or indirectly) has been migrated to null safety, so
that you will be able to run your unit tests in sound null checking mode.  You
are currently importing the following non-null-safe libraries:

  package:stepfly/common/Functions/Constants/constants.dart
  package:stepfly/common/Functions/Utils/random_string.dart
  package:stepfly/common/Functions/Utils/timeUtils.dart
  package:stepfly/common/Functions/Utils/utilExam.dart
  package:stepfly/common/Functions/Utils/utilInternet.dart
  package:stepfly/common/Functions/Utils/utils.dart
  package:stepfly/common/Functions/Utils/utilsResourse.dart
  package:stepfly/common/Functions/Utils/utilsUserData.dart
  package:stepfly/common/Responsive/enums/device_screen_type.dart
  package:stepfly/common/Responsive/platformInfo.dart
  package:stepfly/common/Responsive/responsive/responsive_builder.dart
  ......

Please upgrade the packages containing these libraries to null safe versions
before continuing.  To see what null safe package versions are available, run
the following command: `dart pub outdated --mode=null-safety`.

To skip this check and try to migrate anyway, re-run with the flag
`--skip-import-check`

虽然这些文件是我自己的代码文件。

运行以下命令dart pub outdated --mode=null-safety给我输出如下：

Showing dependencies that are currently not opted in to null-safety.
[✗] indicates versions without null safety support.
[✓] indicates versions opting in to null safety.

Computing null safety support...
All your dependencies declare support for null-safety.

如何使用dart migrate工具将我的颤振代码迁移到空安全

标签： flutterdartdart-null-safety

解决方案

如果我理解正确，您的文件会从您自己的库中导入其他文件。这些文件尚未迁移到空安全（因为这是您想要做的），这就是您收到此错误的原因。

尝试使用提到的再次运行它

To skip this check and try to migrate anyway, re-run with the flag
`--skip-import-check`

我遇到过同样的问题。使用此标志迁移它后，现在一切正常。
