How does compute work?
An app I'm working on is a bit slow (its littered with async calls). I wanted to improve its performance, researched on isolates and after implementation, the functions were significantly slower. The phone I'm debugging with is not a fast one so perhaps that wasn't needed but why would compute take significantly longer?I took time to test this out with a simple json decoding function and this is it;Map getMap(String json) {
return const JsonDecoder().convert(json) as Map;
}final Map data = await compute(getMap, json, debugLabel: getMap.toString());The above takes about 30% longer to finish and return a result compared to this;final data = const JsonDecoder().convert(json);Is overengineering the issue here? I tried moving the operation of many other functions in the app to isolates and they were much worse in terms of speed (about 100% slower in some cases). What I'm I doing wrong?

Release 2.2.1 is so disappointing
If you upgrade your app from 2.06 to 2.2.1 be ready for some issues.ListView scrolls way to fast and long. A simple drag gesture will scroll your list for like 5 seconds until the bottom (didn't found a solution)BottomSheet is covered behind the keyboard (we need to get the margin from the keyboard again). Even then it will break the design on the closing animation. (only a partial solution)BottomSheet open performance with autofocus on a textfield or on close with keyboard open is super laggy. On versions before 2.0.6 this was smooth as well. (didn't found a solution)I downgraded back to 2.0.6 because of the ListView issue, no clue if this happens on some circumstances for my app or in general, maybe I will try to reproduce it.

Do you generate your own classes/widgets to interface to flutters widgets
I've just upgraded from 1.x to 2.10, I initially set out to upgrade to null safety but a number of dependencies haven't been migrated as of yet.Along with upgrade I also updated majority of my dependencies, I'm hoping after this step that the step towards null safety is a lot clearer (i.e I don't have to wade through API breaking changes along with null safety).Apart from fixing the breaking changes, what's been really frustrating has been handling flatbutton > textbutton, raisedbutton > elevated button. This was littered throughout my app and each one had to be handled invidually.I ended up generating my own widget which was just a wrapper for the flutter widget. Just so that in the future this is not as painful. I used to do something similar in other languages/frameworks, but I didn't think the buttons will be altered in this way.Just wondering whether anyone else is doing this ?When I first updated I had about 1500 problems, I've been cleaning up over the last couple of days and I'm down to 475.

What Should I do?
I was working on the flutter packages where users can send OTP via email with a custom template, so how can I implement it? is I directly create send email function in dart or write some extra script ( something in python or java ) and upload it on the server.
