How do I get the Signals DevTools extension to show up?

[rydmike]

Hi,

Is there some secret magic sauce needed to get the Signals DevTools extension to actually show up in DevTools? I have not been able to get it to show in DevTools with IJ or VS-Code.

Some extra needed config? How? Where? Any docs for this available somewhere? I could not find it. Found a lot of info about how you build your own DevTools extensions for your packages in a Medium article and some docs, but nothing on how you get them to show up when you use a package that has them. All I see mentioned is that it should be automatic when you use packages that support them, but at least for me it is not.

I really wanted to check out and try the Signals DevTools extension now that it has gotten more features, but so far I have not been able to get it to show up. Thanks a lot in advance for any tips and pointers.

Ok, I just did. No Signals DevTools, not in IJ or VS-Code:

[flutter] flutter doctor -v
[✓] Flutter (Channel beta, 3.18.0-0.1.pre,

[rodydavis]

Fixed on 1.5.10. It was not including it in the pub package upload even though I followed the readme for the dev tools

[rydmike]

I just tried 1.5.10 too, and I can still not get the DevTools extension to show up. Not on IJ or VS-Code using latest Flutter stable or latest Flutter beta. So maybe something else that it is blocking it in my setup, but no idea what 😄

[rydmike]

I had done all upgrades, flutter clean. nope. Closed IJ and VS-Code, clean again, but nope nothing.

So I closed everything and rebooted and built test app again, but no more clean or changes before, and now it worked. Only extra step was a reboot of my MacBook. Weird, but, yey! 😄

Thanks for the assists and the 1.5.10 fix @rodydavis! 👍🏻

Hi guys, @rodydavis @rydmike I'm having the same problem, I can't make the devtools extension to show up:

• I created a new project with Flutter New Project;
• I created a file called devtools_options.yaml with the code below inside:

- extensions:
  - signals: true 

• I copy/pasted the official counter example;
• I run the app in Chrome or emulator with Start debugging or Run without debugging;
• I open Dart: Open DevTools and Open DevTools in browser but it shows "no extensions available" in the DevTools settings, its showing like the picture that @rydmike posted above.
• My pubspec:

name: flutter_signals_sqlite_crud
description: "A new Flutter project."

publish_to: 'none' 
version: 1.0.0+1

environment:
  sdk: ^3.5.4
dependencies:
  flutter:
    sdk: flutter
  cupertino_icons: ^1.0.8
  signals_flutter: ^5.5.1
  sqflite: ^2.4.1
  path: ^1.9.0

dev_dependencies:
  flutter_test:
    sdk: flutter
  flutter_lints: ^4.0.0
  signals_lint: ^5.0.0
  custom_lint: ^0.5.11
flutter:
  uses-material-design: true

Am I missing something? 🫠

[rodydavis]

Looking into it!

Looking into it!

I got it working. The extension works only with signals package, it's not available with signals_flutter.
But it's not working well here, the extension window shows a message 'no nodes created' with this console log:

That is correct! It has to be bundled with one package and not sure if I want to make 1 devtool extension per package
