My Iphone 12 pro max sparked while on charge and totally went dead.

Few days back, I put my Iphone on charge while the battery was totally empty. After few minutes of charge my phone came up normally and it started Charging. So I drop it on charge and behold before I could sit down, my phone sparked on charge and totally went dead up till now. I have charged it for hours to see if it would come up but still not working. Is my phone totally gone or there is still a hope of fixing it?
