Hello.
What version of dart sdk are you using?

BytesBuilder should be exported from 'dart:typed_data';
However I see some information to suggest that it was moved from dart:io.
It looks like its still exported from dart:io, albeit with a deprecated tag

This is what I see in io.dart:203
@deprecated("Import BytesBuilder from dart:typed_data instead")

[isong0623]

i fixed this problem.
thx,you are right.
i modified "src/framework/filters.dart" and "src/framework/sinks.dart" with new line "import 'dart:io'".
the 'git version' works fine,and can decode with java (com.github.luben.zstd.Zstd),
but the 'flutter version' meet new problem
