Generating migration suggestions...
[----------------------------------------------------------------- ]Aborting migration due to an exception. This most likely is due to a
bug in the migration tool. Please consider filing a bug report at:

https://github.com/dart-lang/sdk/issues/new
Please include the SDK version (2.12.4) in your bug report.

To attempt to perform migration anyway, you may re-run with
