Created by: miveronese

Feature flag to show/hide the new page/components.

1.To add the new feature flag, go to the graphql console (in api/console) and create a feature flag and set it to true.

mutation CreateFeatureFlag{
   createFeatureFlag(
       name: "repo-refresh",
       value: true,
  ){
    __typename
  }
}

2. To use the flag You can use it in the RepositoriesFileTreePage.tsx to conditionally display the new TreePage and other components .

 return (
        <>
       …. 
      {!loading && getFlags(data).get("repo-refresh") ? (
       <div> an old components </p>
       ) :  <div> a new components </div>}

    …
)
