I try this but not work, please help me :D

For an App:

Intent()
        ..setAction(Action.ACTION_SEND)
        ..setData(Uri.parse('package:com.whatsapp'))
        ..putExtra(Extra.EXTRA_STREAM, file.path)
        ..startActivity().catchError((e) => print(e));

For an email:

Intent()
      ..setAction(Action.ACTION_SENDTO)
      ..setData(Uri(scheme: 'mailto'))
      ..putExtra(Extra.EXTRA_SUBJECT, 'Subject')
      ..putExtra(Extra.EXTRA_STREAM, file.path)
      ..startActivity().catchError((e) => print(e));
