◆ fl_mouse_cursor_channel_new()

FlMouseCursorChannel* fl_mouse_cursor_channel_new ( FlBinaryMessenger *  messenger,
FlMouseCursorChannelVTable vtable,
gpointer  user_data 
)

fl_mouse_cursor_channel_new: @messenger: an #FlBinaryMessenger. @vtable: callbacks for incoming method calls. @user_data: data to pass in callbacks.

Creates a new channel that implements SystemChannels.mouseCursor from the Flutter services library.

Returns: a new #FlMouseCursorChannel.
