dart migrate 在我自己的代码文件中给出了错误

Question

当我运行“飞镖迁移”以启用空安全时，它给我以下输出。


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the following command: `dart pub outdated --mode=null-safety`.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运行ning 以下命令 dart pub outdated --mode=null-safety 给我输出如下：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 flutter 代码迁移到空安全

Answer 1

如果我理解正确的话，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（因为这是你想要做的），这就是你收到此错误的原因。

用提到的

再试运行

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

我遇到了同样的问题。使用此标志迁移它后，现在一切正常。
