Would be nice if someone can fix this so we don’t need a workaround.

I’m using Yarn 3.2.0 and get the following warning:

➤ YN0002: │ eslint-config-react-app@npm:7.0.0 [07f45] doesn't provide @babel/plugin-syntax-flow (p19435), requested by eslint-plugin-flowtype
➤ YN0002: │ eslint-config-react-app@npm:7.0.0 [07f45] doesn't provide @babel/plugin-transform-react-jsx (p74774), requested by eslint-plugin-flowtype

which can be muted by adding the following to .yarnrc.yml:

packageExtensions:
  # awaiting fix: https://github.com/facebook/create-react-app/issues/11982
  'eslint-plugin-flowtype@*':
    peerDependenciesMeta:
      '@babel/plugin-syntax-flow':
        optional: true
      '@babel/plugin-transform-react-jsx':
        optional: true
