Hey @zenjava! We really appreciate you taking the time to report an issue. The collaborators
on this project attempt to help as many people as possible, but we're a limited number of volunteers,
so it's possible this won't be addressed swiftly.

If you need any help, or just have general Babel or JavaScript questions, we have a vibrant Slack
community that typically always has someone willing to help. You can sign-up here
for an invite.

Can you follow the issue template? Thanks! I believe you are asking about the flow-comments plugin but not sure.

If you just have an usage issue or want help, I would recommend checking out our slack community or StackOverflow.

[zenjava]

Ok ,I have changed the way to the template!

I'm curious, have you explored using .js.flow files instead of comments? The transform-flow-comments plugin is definitely buggy.

[zenjava]

Yes, I'm used transform-flow-comments plugin.
