React-native: Toggling inspector causes redirect to first screen in stack navigator

[nathsimpson]

I'm attempting to debug some layout issues in a React Native app. When I open the dev tools menu in the iOS Simulator, and hit 'Toggle Inspector', the app jumps back to the first screen in the react-navigation Stack Navigator, and I am unable to get back to the screen I wanted to inspector without turning off the Inspector.

Has anyone else found this issue? I can't provide a link to the repo, however I can answer any questions you have.

Steps To Reproduce

1. Open your React Native app in the iOS simulator
2. Navigate to a screen which is at leave one level deep in your stack navigator
3. Open the dev tools menu (CMD-D), and press 'Toggle Inspector'
4. Inspector appears on the first screen of the stack, and you can't get back to the other screen without disabling inspector.

Describe what you expected to happen:
Inspector UI appears on the screen you are currently on, rather than being taken back to the first screen.

My mistake. This is due to me not understanding how the Inspector works 🤦‍♂

For anyone who has this issue, once you open the inspector, you can switch it on/off by pressing the 'Inspect' button on the toolbar. This will allow you to navigate the app, then turn it on so you can inspect the element you need to.

There seems to be a lack of docs on React Native Inspector, but here is what I did find. https://facebook.github.io/react-native/docs/debugging#integration-with-react-native-inspector
