title: Dynamically fill some data in android/app/build.gradle (React Native ap)
body: <p>For my react-native application I am using <a href="https://github.com/FormidableLabs/react-native-app-auth" rel="nofollow noreferrer">react-native-app-auth</a> library.</p>
  
  <p>I need to fill this info in build.gradle file, for android:</p>
  
  <pre><code>android {
    defaultConfig {
      manifestPlaceholders = [
        appAuthRedirectScheme: 'io.identityserver.demo'
      ]
    }
  }
  </code></pre>
  
  <p>But <em>appAuthRedirectScheme</em> can be different for some roles of users. And I need to send this scheme directly from react-native components (when I get that scheme/url from another API).</p>
  
  <p>Is there any way to do this?</p>
