1 Install and launch React Native Debugger

The first step is to install React Native Debugger on your computer. You can download it from the official website or use a package manager like Homebrew. Once you have installed it, launch it and make sure it is running on the same port as your React Native app. You can change the port number in the settings menu if needed.

2 Connect your app to React Native Debugger

The next step is to connect your app to React Native Debugger. You can do this by enabling remote debugging in your app. On iOS, you can shake your device or use the simulator menu to open the developer menu and select Debug JS Remotely. On Android, you can press Ctrl+M or Command+M on your keyboard or use the device menu to open the developer menu and select Debug. You should see a message saying that your app is connected to React Native Debugger.

3 Use the console and network tabs to find errors and requests

The third step is to use the console and network tabs to find errors and requests that may cause your app to crash. The console tab shows you the logs, warnings, and errors from your app and the React Native runtime. You can filter the messages by type, level, or source. You can also use the console as a REPL (read-eval-print loop) to execute JavaScript code in the context of your app. The network tab shows you the requests and responses that your app makes and receives. You can inspect the headers, body, and status of each request and response. You can also filter the requests by type, method, or status.

4 Use the React and Redux tabs to inspect components and state

The fourth step is to use the React and Redux tabs to inspect components and state that may affect your app's behavior and performance. The React tab shows you the component tree of your app and lets you select and inspect each component's props, state, hooks, and context. You can also edit the props and state of any component and see the changes reflected in your app. The Redux tab shows you the state tree of your app and lets you select and inspect each action and state change. You can also dispatch actions, replay actions, and jump to any state in the history.

With these four steps, you can use React Native Debugger to analyze mobile app crashes and find the root cause of the problem. You can also use React Native Debugger to optimize your app's performance, layout, and styling.

With introduction of Flipper you can use all the debugging related work in React Native. You need to enable flipper in pod and for redux you need to add debug code in store, also you need to enable which plugins you want to use. i have recently used it in an app built in typescript and solve many issues.
