Bad state: Future already completed when using CachedNetworkImageProvider

[mark8044]

The package works wonderfully when using NetworkImage provider

final imageProvider = NetworkImage(imageUrl);
final String blurHash = await BlurhashFFI.encode(imageProvider);

However, when trying to use a CachedNetworkImageProvider:

final imageProvider = CachedNetworkImageProvider(imageUrl);
final String blurHash = await BlurhashFFI.encode(imageProvider);

Then we get the following error:

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: Bad state: Future already completed
#0      _AsyncCompleter.complete (dart:async/future_impl.dart:43:31)
#1      BlurhashFFI._getImageInfoFromImageProvider.<anonymous closure> (package:blurhash_ffi/blurhash.dart:195:17)
<asynchronous suspension>

Despite the error, a blur hash string is still returned....
