The change in [0] has propagated now everywhere, so we can use `utf8.encode()` instead of the longer `const Utf8Encoder.convert()`. Also it cleans up code like ``` TypedData bytes; bytes.buffer.asByteData(); ``` as that is not guaranteed to be correct, the correct version would be ``` TypedData bytes; bytes.buffer.asByteData(bytes.offsetInBytes, bytes.lengthInBytes); ``` a shorter hand for that is: ``` TypedData bytes; ByteData.sublistView(bytes); ``` [0] https://github.com/dart-lang/sdk/issues/52801
