i am having trouble to migrate my flutter app using dart migrate

short intro: so i was doing migration, the other local package that i put inside my project are migrated successfully using dart migrate

the only problem is the top level project, always showing isDartAsyncFuture was called on null

maybe someone can help me to successfully migrate the top level project

here's the error log, verbose only showing the time no additional error shown:

dart migrate
Migrating D:\dev\workspace\my_project

See https://dart.dev/go/null-safety-migration for a migration guide.

Note: more than one project found; migrating the top-level project.

As of 1c7fe7196dd7a542f7f91cd6ea2ac81e1a13146c, the null safety migration tool has been removed from active development and retired. No further work on the tool is planned.

If you still need help, or you believe this issue has been closed in error, please feel free to reopen.
