The error is at _buildList ({ @required List<UserResult> members }) { ... }

I've followed /example/lib/page/more/support.dart which is the simplest.

Note that the bloc pattern does not affect the overall build. Assume that data has loaded successfully and executed _buildList ({ @required List<UserResult> members }) { ... }

Following result that I've tried:

  1. If scroll is slow, it will not cause the error. Footer will appear as expected.
  2. If scroll is fast, error is thrown. Footer will not appear.

Fixed，before releasing the new version, you can use git to import it.
