I make extensive use of

TextMeasurer

in my composables. Should I be passing this around as an argument (many composables) or just using

rememberTextMeasurer

where needed?

It depends on how you are utilizing the internal cache of TextMeasurer. Every

rememberTextMeasurer

would initialize a new

TextMeasurer

for you with a separate cache. If you are not using the cache (as in specifying

cacheSize

as 0) then you can safely pass the

TextMeasurer

to other composables and save yourself extra few allocations. However, if you are taking advantage of the internal cache, then all your

measure

calls in all the different composables would be hitting the same cache. If you do not have a sufficiently large sized cache, then you may run into lots of cache misses which would be a more serious problem for performance. In that case I'd recommend you to just use

rememberTextMeasurer

in each Composable.
