QUESTION
I'm new to react native and trying to design a custom Bottom navigation bar as shown here (Source code)
The tab bar design is successfully created, but I am confused about how to change screens on button click. Basically, I cannot understand how to connect the React Native Navigation Component to this custom bottom tab bar.
I'm looking forward to using React navigation custom navbar support... but not sure how to implement the same.
Please help.
Thanks in advance.

Answered 2020-Oct-21 at 14:53I've never tried to do that, but you probably can do that by using default stack navigator: https://reactnavigation.org/docs/navigating So, what is the idea. You create 5 different screens and on each of them make a copy of this tabbar. Then you write a conditional statement for every possible case with navigation.navigate prop. I think this is the only way, but I don't know how that will affect the performance of the app
QUESTION
I've tried to integrate this example into my code base (without TSX), but when trying onScroll={onScroll({ y })}
. I get the following error (0, _reactNativeRedash.onScroll) is not a function
.
I'm not sure what the cause of the problem is since I've followed the example to the letter (only changing it to regular JS)
Whenever I comment out the onScroll={onScroll({ y })}
with console.log("y", y);
and try to log the y
value in the ListBody
component I get an memory leak (memory used keeps climbing).
Still not sure why the memory leak happens or what I'm doing wrong to cause the bug.
The problem: I get the following error (0, _reactNativeRedash.onScroll) is not a function
whenever component loads (Snack)
What I've tried: Removed all inner content of the scrollView, different ways of passing on the props like y={y}
or animV={y}
, finding the solution online.
What I expect: y
Value to change with the scroll

had been changed to onScrollEvent
and the problem has been solved
