flipper VS simple-stack

Definitely switch to VS Code! I personally don't use the built in VS Code debugger, but check out Flipper as another option. It's got a lot of great tools and plugins for debugging. The Layout Inspector will be what you are looking for if you want to inspect the styling specifically.

I use Flipper with its Layout Inspector plugin

Also no folder show on sources filesystem (in Hermes Debugger) as described here: https://github.com/facebook/flipper/issues/4530

Very useful and beautiful and simply , my suggestion is to use this Flipper

You may also want to look into custom Flipper plugins to instrument your app.

Some development tools for the web are similar (Chrome debugger, mostly) to those for React Native, but other aspects are very different (working with the metro bundler, using Flipper, AsyncStorage debugging, more). Some techniques developers will use are the same (breakpoints and console logging), but others are different (knowing when to restart the packager vs reinstall the app on device).

from the GitHub, and has existed under the name flipper since mid 2018

It's not possible to use a browser to debug a JSI app, use Flipper (for android Flipper also has SQLite Database explorer).

Try to debug it with adb logcat or Android Studio or Flipper you'll find the error why is crashing :)

As someone who had been using single-activity since 2015 (a'la Flow) and eventually just rewrote the whole thing to fix all the bugs we had with it in 2017, I find it sad that the single-activity approach was questioned not because it was harder, but because people made their own lives harder. And then Google made their lives harder.

I've been using single-activity but with Simple-Stack since 2016 and never deprecated it because Navigation just has these quirks that impede you a lot. I know how to use it but wouldn't really pick it.

This is why we've been using https://github.com/Zhuinden/simple-stack and it was never deprecated. We've been using it for 6 years, I'd say there was a critical bug but it was fixed in 2.3.1...

I mean, we use Simple-Stack because it makes things easier, if it didn't we'd have ditched it long ago https://github.com/Zhuinden/simple-stack

Agreed. I also added support for it 2 weeks ago.

I don't, because we use this and it's better than activities+intents 😅

We've been making single activity apps with https://github.com/Zhuinden/simple-stack and it has been easier than multi-activity.

I still use https://github.com/Zhuinden/simple-stack to this day, although I still use it with fragments.

I have been using Fragments instead of compound viewgroups lately with simple-stack as the navigator for the single-activity, although I need to figure out how to switch to use onBackPressed+onBackInvokedCallback and not just onBackPressed.

You can think of Simple-Stack as a direct successor of Mortar+Flow.
