How to fix warning caused by Flow Function Types using eslint-plugin-react?

Question

I'm getting a warning on the following line on my react component

handleToggle: Function;

I'm using eslint-plugin-react and Flow and I'm getting a warning "handleToggle should be placed after constructor". This is related to rule react/sort-comp. I tried with the following on my .eslintrc.json

 "react/sort-comp": [1, {
  "order": [
    "static-methods",
    "lifecycle",
    "everything-else",
    "render"
  ],
  "groups": {
    "lifecycle": [
      "displayName",
      "propTypes",
      "contextTypes",
      "childContextTypes",
      "/^.*: Function$/",
      "mixins",
      "statics",
      "defaultProps",
      "state",
      "constructor",
      "getDefaultProps",
      "getInitialState",
      "getChildContext",
      "componentWillMount",
      "componentDidMount",
      "componentWillReceiveProps",
      "shouldComponentUpdate",
      "componentWillUpdate",
      "componentDidUpdate",
      "componentWillUnmount"
    ]
  }
}]

But I'm unable to fix the warning. I want the Function Types before constructor the same as the other Type Definition. How can I achieve this?

you can now add a "new" item (type-annotations)* to the order section in the config:

"react/sort-comp": [
  2,
  {
    "order": [
      "type-annotations",  // <-- this is "new"
      "static-methods",
      "lifecycle",
      "everything-else",
      "render"
    ],
    "groups": {
      "lifecycle": [
        "displayName",
        "propTypes",
        "contextTypes",
        "childContextTypes",
        "mixins",
        "statics",
        "defaultProps",
        "constructor",
        "getDefaultProps",
        "state",
        "getInitialState",
        "getChildContext",
        "getDerivedStateFromProps",
        "componentWillMount",
        "UNSAFE_componentWillMount",
        "componentDidMount",
        "componentWillReceiveProps",
        "UNSAFE_componentWillReceiveProps",
        "shouldComponentUpdate",
        "componentWillUpdate",
        "UNSAFE_componentWillUpdate",
        "getSnapshotBeforeUpdate",
        "componentDidUpdate",
        "componentDidCatch",
        "componentWillUnmount"
      ]
    }
  }
]

after this, eslint will stop complaining.
