Import Blender-xxx.blend files in unity (-90º X Axis)

Unity Engine

model a simple cube with a flattened shape, it has no related objects, no rotations, nor is it located in any coordinate other than (0,0,0) xyz, it does not have any rotation, it does not have animations,
only has one material and one texture, apply scale in blender with CTRL + A / Rotation, Scale
but when I drag the file from the blender folder to the unity interface and drop it, I’m going to check the properties of the object, and I notice that it marks a negative rotation in the AXIS X, which in blender does not exist.
Why do you think of this? Is it a bug that you are not interested in fixing at all? or is there someone who tells me how to correct it?

It’s not really a bug, it’s due to Unity different axis system. Blender use the direct system (x, y, z) and Unity use the indirect system (x, z, y). The -90 x rotation is due to the conversion. The best solution is to apply a +90 x rotation in Blender.
