Use of Collapse UI component in Grafana v8

Hello,

I want to upgrade some of my plugins from V7 to V8 but I have some compilation errors with types.

As a minimal example, I tried to initiate a new plugin with GrafanaToolkit and replace its body with a Collapse component:

import React from 'react';
import { PanelProps } from '@grafana/data';
import { SimpleOptions } from 'types';
import { Collapse, } from '@grafana/ui';

interface Props extends PanelProps<SimpleOptions> {}

export const SimplePanel: React.FC<Props> = () => {
  return (
      <Collapse label={'coucou'}>
        <p>Panel data</p>
      </Collapse>
  );
};

This gives me the following error:

yarn run v1.22.15
$ grafana-toolkit plugin:dev
✔ Linting
⠦ Bundling plugin in dev mode  TS2322: Type '{ children: Element; label: string; }' is not assignable to type 'IntrinsicAttributes & Props'.

Node version: v14.19.1

Grafana UI version:

yarn.lock
1222:    "@grafana/ui" "8.5.0"
1300:"@grafana/ui@8.5.0", "@grafana/ui@latest":
1302:  resolved "https://registry.yarnpkg.com/@grafana/ui/-/ui-8.5.0.tgz#47c107af1376bfbdbbddef5cb3b262963864b4e4"

What’s wrong?

Looks like @types/react version 18.0.1 or higher is installed (probably 18.0.5).
In @types/react v18.0.1 they removed children from FunctionComponent, but Grafana still uses React v17.

A quick fix is to install @types/react v17
yarn add @types/react@^17

Indeed, this is what rg @types/react -A 3 found in my yarn.lock file:

2419:"@types/react@*":
2420-  version "18.0.5"
2421:  resolved "https://registry.yarnpkg.com/@types/react/-/react-18.0.5.tgz#1a4d4b705ae6af5aed369dec22800b20f89f5301"

2423-  dependencies:
2424-    "@types/prop-types" "*"

After the yarn add the example compiles ! :+1:

V18 is still there though:

2460:"@types/react@*":
2461-  version "18.0.5"
2462:  resolved "https://registry.yarnpkg.com/@types/react/-/react-18.0.5.tgz#1a4d4b705ae6af5aed369dec22800b20f89f5301"

Should I do something about it?

You could remove the other version, but it should be fine leaving it.
You could also remove the entire yarn.lock file and run yarn install, which should just keep the needed @types/react dependency
