Waving flag animation in blender to unity

I created a flag in Blender that moves in the wind by clicking alt+a (apparently that’s not what I should click). But when I try to export it to Unity it doesn’t save the animation. How can I create the animation so it would save when moving it to Unity?

This is my blender file flag

  1. If you are exporting your blender model to unity by exporting other format and then to unity try the drag and drop your .blend file in to unity.Check that you have only one animation in your blend file.

  2. I suggest you that you should the normal map for your flag animation.
