HatangFilePick typedef

HatangFilePick = Future<UploadSource?> Function()

Lets the visitor pick a file of any type, or null when they cancel.

The SDK does not depend on a file picker itself, so apps choose theirs (and its version): package:hatang_chat/file_picker.dart provides HatangFilePick over file_picker, or wrap your own.

Implementation

typedef HatangFilePick = Future<UploadSource?> Function();
