How do I put a blender file into Unity properly?

Hi.
I finished few objects in blender, painted it and saved it (as .fbx and .blend).
But when I drag it into unity, my object comes without textures.

I just started trying to work with some 3D games and Models, so my experience is 0. I watched few tutorials on how to model on blender and how to get a file from blender to unity, but it didn't work well.
Is there a way I could save the textures as material in blender and insert it on unity? Or am I forgetting something in blender?

What I did in blender was:
Molded the object. Got into the texture paint tab. Created a texture and painted with stencil.
Then I got back into layout tab and changed the viewport to Texture so I could see in layout mode.
Saved the file as fbx and blend.

Thats it. Am I missing something?

I've not used Blender in a while so maybe someone will have a better answer but you should be able to save your texture in Blender as an image and then import that image to Unity separately, then you can just apply it to the model.
