[iapicca]

fix #6768

updating the current coda sample with the following

new code sample

import 'dart:async';
import 'dart:convert';

import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';
import 'package:http/http.dart' as http;

Future<List<Photo>> fetchPhotos(http.Client client) async {
  final uri = Uri.parse('https://jsonplaceholder.typicode.com/photos');
  final response = await client.get(uri);

  // Use the compute function to run parsePhotos in a separate isolate.
  return compute(parsePhotos, response.body);
}

// A function that converts a response body into a List<Photo>.
List<Photo> parsePhotos(String responseBody) {
  final parsed = jsonDecode(responseBody) as List;
  return [for (final json in parsed) Photo.fromJson(json)];
}

@immutable
class Photo {
  final int albumId, id;
  final String title, url, thumbnailUrl;

  const Photo({
    required this.albumId,
    required this.id,
    required this.title,
    required this.url,
    required this.thumbnailUrl,
  });

  factory Photo.fromJson(Map<String, Object?> json) {
    return Photo(
      albumId: json['albumId'] as int,
      id: json['id'] as int,
      title: json['title'] as String,
      url: json['url'] as String,
      thumbnailUrl: json['thumbnailUrl'] as String,
    );
  }
}

void main() => runApp(const MyApp());

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);
  static const _appTitle = 'Isolate Demo';

  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      title: _appTitle,
      home: MyHomePage(title: _appTitle),
    );
  }
}

class MyHomePage extends StatelessWidget {
  final String title;

  const MyHomePage({Key? key, required this.title}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(title),
      ),
      body: FutureBuilder<List<Photo>>(
        future: fetchPhotos(http.Client()),
        builder: (context, snapshot) {
          if (snapshot.hasError) {
            print(snapshot.error);
            return const Center(child: Icon(Icons.error));
          }
          return snapshot.hasData
              ? PhotosList(photos: snapshot.data!)
              : const Center(child: CircularProgressIndicator());
        },
      ),
    );
  }
}

class PhotosList extends StatelessWidget {
  final List<Photo> photos;

  const PhotosList({Key? key, required this.photos}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return GridView.builder(
      gridDelegate: const SliverGridDelegateWithFixedCrossAxisCount(
        crossAxisCount: 2,
      ),
      itemCount: photos.length,
      itemBuilder: (context, index) {
        return Image.network(photos[index].thumbnailUrl);
      },
    );
  }
}

@miquelbeltran, please review

[miquelbeltran]

Hi @iapicca All the code changes need to be done on the original dart files as well and exported using the refresh code excerpts tool, rather than editing the mark down directly. Please look at the README.md and the https://github.com/dart-lang/site-shared/blob/master/doc/code-excerpts.md for more info on how to do it.

[sfshaza2]

That's what I was kind of assuming, but I didn't take the time to look at the site. @iapicca, are you willing to tackle that? If not, I will close the PR.

[iapicca]

@sfshaza2
I'm definitely willing to try;
I asked guidance on discord, because the instructions are not clear to me
any help is appreciated

[miquelbeltran]

I think I spotted a couple of issues.

[sfshaza2]

Is this ready? Do you approve, @miquelbeltran?

[miquelbeltran]

@sfshaza2 the code excerpts are not correct yet, I run the ./tool/refresh-code-excerpts.sh localy and got changes still. Also the GitHub workflow needs run approval, but I cannot do that.

[iapicca]

[..] the code excerpts are not correct yet

@miquelbeltran
I applied the changes requested here and here in this commit
I'd be happy to fix the excerpts on a feedback

[sfshaza2]

I've kicked off the workflow. @domesticmouse, do you have the privilege to kick off the workflow?

[domesticmouse]

My laptop is borked. I'm currently at seriously reduced capability.

[iapicca]

I see both tests

• Stable channel: code check, stable, tool/check-code.sh, false) (pull_request)
• Stable channel: null safety code check, stable, tool/check-code.sh --null-safety, false)

fails with the same output

Hey @iapicca, going from the logs, I suspect you need to update some snippets. The log includes the following instructions:

going from the logs, I suspect you need to update some snippets. The log includes the following instructions:

  Processed 388 Dart/Jade/Markdown files: 3 out of 338 fragments needed updating.
  
  Error: some code excerpts need to be refreshed. You'll need to
  rerun '/home/runner/work/website/website/tool/refresh-code-excerpts.sh' locally, and re-commit.

@domesticmouse
when I run 'tool/refresh-code-excerpts.sh' I get this error

/home/yakforward/projects/website/tool/env-set.sh: line 7: tool/shared/env-set.sh: No such file or directory

which makes sense since site-shared/ does not contain tool

I'm probably missing something, as I mentioned I'm having hard time to understand the instructions provided

[domesticmouse]

Hey @johnpryan and @miquelbeltran, can you please have a look at this PR and give some guidance? I'm out of my depth here.

tool/shared/env-set.sh: No such file or directory

Looks like your setup is not correct, you need to follow all the steps in the README.md (e.g. site-shared is a submodule which you need to update: https://github.com/flutter/website#2-clone-this-repo-and-its-submodules)

Refreshing Flutter repo and running doctor:

Branch 'stable' set up to track remote branch 'stable' from 'origin'.
Switched to a new branch 'stable'
+ git pull
hint: Pulling without specifying how to reconcile divergent branches is
hint: discouraged. You can squelch this message by running one of the following
hint: commands sometime before your next pull:
hint: 
hint:   git config pull.rebase false  # merge (the default strategy)
hint:   git config pull.rebase true   # rebase
hint:   git config pull.ff only       # fast-forward only

hint: You can replace "git config" with "git config --global" to set a default
hint: preference for all repositories. You can also pass --rebase, --no-rebase,
hint: or --ff-only on the command line to override the configured default per
