Flicker in animation...,Weird Blinking in animation..

I am making a game having an animation where the character is running…
But whenever I run it, the animation kind off flickers

Please help me. I am a newbie to this!

It looks to me like it’s missing a sprite or the animation is set to one frame too long. Can you show us a screenshot of your animation timeline?
