Feature Request: Add [Show Dev Menu] when specific error occurs.

[321paranoiawhy]

Introduction

When this specific error occurs:

Unable to load script. Make sure you're either running Metro (run 'npx react-native start') or that your bundle... 

at the bottom of screen, we can see [DISMISS] and [RELOAD] button for developer convenience.

But can we have a button [Show Dev Menu]?

Details

Why we need this button?

So far, we have and only have two methods to achieve the function of the button:

• Shake the device, when it is a physical device, we can shake it by hands; when it is a emulator, we can click some button to shake the emulator

• use adb command when it is an android emulator:

  adb shell input keyevent 82

In most cases, these are enough. But in these cases none of those function well as supposed:

• the physical device can not response to shake
• the android emulator keyevent 82 has been used for another function

That's why we need the button for showing dev menu.

Some help

Out of curiousity: why would you want to open the dev menu on a error screen?

Sometimes in this screen，we could not show dev menu in any methods because of device limitations or other reason, and this scene should be exactly happened.

Show dev menu so that we can set the server ip:host to correctly connect, or do something else.

Of course, this button can be also a convenience for developer, so we do not need shake the device, we just click the button which is more efficient, convenient and noticeable than shake device to show dev menu.
