dart迁移会在我自己的代码文件中产生错误。

Question

当我运行"dart迁移“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the following command: `dart pub outdated --mode=null-safety`.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`

而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运行以下命令dart pub outdated --mode=null-safety将给出如下输出：

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 工具将颤振代码迁移到空安全

Answer 1

如果我正确理解您的文件，则从您自己的库导入其他文件。这些文件还没有迁移到空安全(因为这是您想要做的)，这就是为什么您会得到这个错误。

试着用上面提到的

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

我也有过同样的问题。在使用此标记迁移它之后，现在一切正常。
