Why would this sometimes be a Uint8List and sometimes not? is it OS dependent?

Although, I suppose it doesn't really matter, before we would ALWAYS call Uint8List.fromList(chunk)

It's not OS dependent and it should always be a Uint8List.
The File.openRead() function returns a Stream<List<int>>, but the underlying type is actually a Uint8List (https://github.com/dart-lang/sdk/blob/main/sdk/lib/io/file_impl.dart#L29)
I don't know why the types do not match, though I think it's mainly for historical reason. But since it's not reflected from the API, I'm treating this as an implementation detail.
I wrote it this way mostly to satisfy Dart's type checking. It's faster than Uint8List.fromList because fromList always copy the bytes, and it's safer than a direct type cast because that would depend on the implementation details. I fully expect it to always hit the first branch though :)

SGTM, thanks for the explanation, was mostly curious.

List of changes: 1. Optimizations in FileTransfer. a. Use `stream.forEach` instead of `await for`. b. Type cast `List<int>` to `Uint8List` instead of using `Uint8List.fromList` results in (presumably) fewer copy and faster execution. c. Iterate through `Uint8List` with regular for loop instead of for-in loop. 2. Precache the block hashes of a file, and reuse it on subsequent runs.
