Because animated_splash_screen 1.1.0 depends on page_transition 2.0.1-nullsafety.0 and no versions of animated_splash_screen match >1.1.0 <2.0.0, animated_splash_screen ^1.1.0 requires page_transition 2.0.1-nullsafety.0.

So even using page_transition: ^2.0.1-nullsafety.0 it still gives the same error

I'm having the same issue

sumitsharansatsangi commented 3 years ago

I am also facing the same issue. I resolved it by removing the page transition field from it. Although it is not a perfect solution because the page transition has gone.

JoelFickson commented 3 years ago

I have had the same issue, and the solution at this point is to remove page_transition.

jeremiahsherrill commented 3 years ago

It's the only way to fix it that I have found. It would be nice if the creator would come up with a solution or just go ahead and remove that feature.

i don't know why, some of the PageTransitionType will work expect. I choose use PageTransitionType.fade, hope help for you
