"Error in FlutterFlow Test Mode

Troubleshooting

ID:ccpla-6ftoof

When I run the test mode, the following image is displayed, and the test mode verification screen does not appear.
It seems that the blur feature I am using in FlutterFlow, flutter_blurhash version 0.7.0, is causing an error.

The error message is:
"Type ‘DecoderCallback’ not found."

Could you please help me resolve this issue?
