Question :: How *heavy* compute() is if called frequently multple times.
I am looking at compute() as a quick way to use threads rather going to long road of creating and managing Isolate instances myself.​But reading the documentation, it will create an isolate behind, and will destroy and clean it after execution is done.​Is there any concept of isolate pool or alike (thread pools)?And what if I need to call compute() frequently for different methods/results?Is it going to tackle and clean every `Isolate` instance or not?And how heavy is it to do so? By heavy say 6-10 different calls in a matter of a second or two.

Do you think Flutter and Flutter web could compete with React Native and React?
Hello everyone,I'm quite new with Flutter, I'm actually taking a Udemy course and I'm really enjoying it.But I was wondering if Flutter and the new Flutter_web could be used in companies in the future, I'm seeing a lot of companies that are seeking React, and/or React Native skills.I know that Flutter is really new but do you think Flutter and Flutter web skills could land me a job in maybe 1 or 2 years? Thanks.

dart:convert or json_serializable
I am trying to assess performance using* dart:convert* and *json_serializable*. I am testing same JSON file (~800KB size), and I don't see any performance when using json_serializable? Both perform... meh, or at least slower than say GSON in Anroid. So from performance standpoint only, is

compute() questions
I have a small data layer, which wraps backend apis requests/results and provides expected data (models) entirely from JSON results. Some of these JSON responses are big (~800KB), and I am trying to figure out using *compute()* since it's easier comparing of dealing with *Isolate * directly.

How to show the menu of PopupMenuButton from the code.
PopupMenuButton opens a menu when user clicks on it. But how do I do open the same menu at the same place as the PopupMenuButton from the code(e.g. due to another user event)?​Edit: I am trying to create a nested menu in the AppBar. Like when user clicks on "Sort by" then menu changes to something else. Is there another way to achieve this? I could not find it on the internet.

Global Variables when an App is closed
When the user leaves the app, i.e. minimizes it, What happens to the global variables? I've found sometimes they persist and sometimes they do not. When the user reopens the app is there a call to redraw the widgets? I've found a workaround to store global variables in shared_preferences, but

How to I write long paragraphs?
I’ve been using flutter for awhile and I’m starting to develop an app that will have a lot of text and information written in long paragraphs with various fonts and styles. The Text() widget doesn’t seem to allow me to style parts of my sentences, and the Text.rich() seems to do okay with text spans but it feels like there should be a better way to do this. HTML does a good job of this, but I’m wondering if I’m expecting too much from a new technology.

Self deleting firebase entries
Whats up guys!Say you want to add a special to my firebase database thats connected to my app that displays them... you want special to be from 22 May to 25 May, how will you program it to delete itself on 26 May? Would it be a cloud function or can I do it through flutter? How would you go from a date in firebase to a day (monday, tuesday and so on) on the app? And are there any software to allow users to add specials based on wheter they habe paid for the month? Thanks in advanced! :))

Race conditions in Dart
Hi,
I am curious, can using variables in both an async function and in a regular (or another async) function lead to race condition or problems due to the fact that the variable is accessed by multiple threads?​In my case I am building an async function that needs to wait while a callback is still in a queue, so I have while loop that just loops infinitely while the callback is still in the queue.
