Description

Issue: getsentry/team-mobile#153

We can use rootIsolateToken but this is currently blocked by Flutter min version 3.7

You can also use Isolate.debugName, which has no such limitation. It's also not specific to Flutter, but to dart:io. But then again rootIsolateToken is also bound to dart:io and web has no threads.

[buenaflor]

Main reason why I don't necessarily want to use it is because it's mutable

PlatformDispatcher.instance.setIsolateDebugName(...)

unlikely that someone does that but it could lead to some unwanted results

in any case, we're planning on bumping the dart version quite a bit in v9 so this shouldn't really be an issue there

[ueman]

rootIsolateToken on the other hand is non-null on the main-isolate vs null on non-main-isolates. So it has less information than Isolate.debugName. (Not saying that one is better, just that each has their own drawbacks)

[buenaflor]

we could verify that the current Isolate is in the main isolate or not with rootIsolateToken and then we know that the Isolate.current.debugName is referring to the main isolate and not any other and use it then properly

these are only edge cases though
