[Navigation CodeLab] Account type is not Changing and navigating to Overview Screen

[amandeepcodes]

When I am clicking on any AccountType it is showing only the first clicked Account Type in Navigation and also when it is showing Single Account screen, Navigation moves to Overview Tab.

when I am following the this codelab, I found the same problem you mentioned above, to confirm this problem, I downloaded the end version code, and the end version code indeed had the bug, so I sloved it.

the problem occurred because this line of code.
val currentScreen = rallyTabRowScreens.find { it.route == currentDestination?.route } ?: Overview

for a quick answer, just replace it with this line:
val currentScreen = rallyTabRowScreens.find { it.route == currentDestination?.route || (it == Accounts && currentDestination?.route?.startsWith( SingleAccount.route ) == true) } ?: Overview

for a deep explanation, continue to read. when you navigate the single_account, actually this page's route can be one of the following:

• single_account/Checking
• single_account/Home Savings
• single_account/Car Savings

of course, all of them can not match the tab routes: overview, accounts, bills, so the original code fall back to the overview page.

to solve this, you just need to add a condition to say that if the current route beyond the tab routes, but it starts with single_account, then the accounts tab should be highlighted.

hope this can answer your question.
