title: Integrating webview inside Flutter for native SDK
body: <p>I came across this issue while I was trying to integrate this native SDK with flutter.</p>
  <p>SDK link: <a href="https://github.com/tinypass/piano-sdk-for-android/blob/master/composer/README.md" rel="nofollow noreferrer">Piano Composer SDK for android</a></p>
  <p>This native SDK populates an inline webView with a given activity ID. But the issue is, the <code>ShowTemplateController</code> class of this SDK (example link below) expects a webView with a specific ID.</p>
