flipper VS react-native-debugger

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 :)

I used to use this which has what I'm talking about, but I've had issues running it with hermes.

https://github.com/jhen0409/react-native-debugger, It is a great tool to debug redux , it comes with the default debugger like we use in web to debug redux.

react-native-debugger

Alternatively, instead of using the adb tool, you can also use the React Native Debugger app (https://github.com/jhen0409/react-native-debugger) to open the debugger on your device. This app provides a button that you can press to open the debugger, so you don't have to use the adb tool or shake the phone.

I use React Native Debugger, it is all-in-ome debugger (https://github.com/jhen0409/react-native-debugger).

React Native is a great tool for certain jobs. Depending on what you're trying to build, Swift may or may not be a better fit. As for debugging, React Native Debugger can be your best friend. https://github.com/jhen0409/react-native-debugger

There are many ways to debug your app by reaching for tools like React Dev Tools, a simple element inspector or a network tab that you're used to. Tools such as React Native Debugger are also quite popular, but they require turning on the 'Remote debugging' mode on your simulator, which I found sometimes interferes with the app and throws weird errors.
