1- Is there a way to speed up first run ?
I wouldn't worry too much about that. I assume you're running these benchmarks in JIT mode? All Dart JIT programs get faster as you run them.
You'll probably see some initial slowness even in AOT. There's some initialization logic that happens the first time you use a class or method (eg looking up symbols in the dylib, loading the class etc).
The first benchmark is dominated by these sorts of issues. But you said those times are all in μs, so I don't think this will be noticable to users.
2- Is there more efficient way to convert
NSArray
toList<String>
?
Not at the moment. I would like to improve NSArray
's bindings so that you can use it like an ordinary List
. Then you won't actually need to convert it. Something like package:jni's JArray
.
I am building a package to get IANA timezone ID and list of supported timezones using native binding. And comparing my package to other package that uses method channels it seems slower in some situations

Speed numbers in
μs
Here are some benchmarks on MacOS App in release mode:
Get current time zone ID
I ran the benchmark multiple times, what I have observed:
Get list of supported timezones
I ran the benchmark multiple, what I have observed:
NSArray
toList<String>
is the cause of slownessAfter the benchmarks : 1- Is there a way to speed up first run ? 2- Is there more efficient way to convert
