Flutter, import show keyword

Question

import 'dart:convert' show JSON;

As far as I know the "show" keyword bring the only one class from library right

but I can`t find now JSON class where is it? I jumped to dart:convert and then I don`t see any on "Class JSON"

why is that?

As you have discovered, JSON is not a class from dart:convert. What you might want is json:

import 'dart:convert' show json;

Which is defined in the dart:convert librart in the json.dart file:

I can see the part 'json.dart'; this is it?? it could be a file name, not just a class? because I can see the "class json" either – dontknowhy Oct 05 '21 at 00:11

It's an instance of a class, I updated my answer to include an image of the source code. Otherwise you can ctrl+click to see it for yourself – Lulupointu Oct 07 '21 at 07:10

https://stackoverflow.com/questions/19723063/what-is-the-difference-between-show-and-as-in-an-import-statement this one uses show JSON what do you think? – dontknowhy Oct 10 '21 at 11:54
You don't need to use `show` unless some class names conflict with one defined in your file. – Lulupointu Oct 10 '21 at 14:30
