Rule require-default-props with Flow type definition assignment

[wyze]

Using v6.9.0 with code like the following:

// @flow

import type { Message } from '../types'

type Props = Message

const Component = ({ message }: Props) => (
  <div>{message}</div>
)

export default Component

Crashes with:

Cannot read property 'filter' of undefined

I have a fix for this, and will submit the PR shortly.

Also, in debugging this, it looks like it is not specific to importing the type. It will also throw the same error if you do something like this:

// @flow

type Message = {
  message: string,
}
type Props = Message

const Component = ({ message }: Props) => (
  <div>{message}</div>
)

export default Component

Closing as the PR to fix was merged and released in 6.10.0.
