React-Native Webview html file doesn't show when offline

I'm creating an app using React-Native. I'm using Webview in order to display a local html file in the app. This works perfectly when the phone has internet connection, but otherwise nothing is shown. Is it possible to have Webview display a local HTML file without internet connection?

Webview code:

      WebView        source={{ uri: 'file:///android_asset/test.html' }}      />
