I'm planning to make an animation and to get a chromebook. I know Creative Cloud is on Chrome OS but wil Animate CC run on it?
No. Windows or macOS - similar to the rest of Creative Cloud desktop applications.
Adobe have been showing off Illustrator and other tools running in ChromeOS, but my suspicion is that they are adapted versions of the mobile applications, and not some way of squeezing the Windows version into ChromeOS.
One thing to note, ChromeOS can play back SWFs in Chrome, so if the end goal was to produce animations for ChromeOS users to view, that's possible, but you would need to make the animations in Windows or macOS.
however, is there a way that we can develop adobe animate for chromeOS
AGAIN, GOOGLE FLASH CS5 IN WINE!
ChromeOS is a Linux Distrobution. Adobe cannot develop for Linux. Do you see the problem here
You can use Wine for Flash CS5 and older, which is basically Adobe Animate before Adobe Animate.
