does test automation code, using flutter driver, reside in the same repo of app development

[nbhatt0405]

For normal Android and iOS application automation using appium, all we need is apk or ipa and then we can automate it in our independent code repo(No need to touch the developer's code repo at all).

But it seems that this is not the case with the application developed using flutter framework.
we need to use test folder of the developer's repo to write tests for application developed using flutter framework. Am I correct?
