Flutter check if Asset image exists

Is it possible to conditionally load an asset image, only if it exists? Therefore you could load a default image if it does not exist in the Assets bundle.

One way you can check if the asset image exists is by trying to display it. If it throws an Exception, display a different widget instead.

Future<Widget> getAssetImage(String path) async {
  try {
    await rootBundle.load(path);
    return Image.asset(path);
  } catch (_) {
    return SizedBox(); // Return this widget
  }
}

Otherwise, you can check the AssetManifest.json and cross-check the asset to be used with the list before trying to access it.
