Summary: Ok so this is a doozy. ## Overview There was a report that some console.error calls were being shown as warnings in LogBox but as console.error in the console. The only time we should downlevel an error to a warning is if the custom warning filter says so (which is used for some noisy legacy warning filter warnings internally). However, in when I switched from using the `Warning: ` prefix, to using the presence of component stacks, I subtly missed the default warning filter case. In the internal warning filter, the `monitorEvent` is always set to something other than `unknown` and if it's set to `warning_unhandled` then `suppressDialog_LEGACY` is always false. However, the default values for the warning filter are that `monitorEvent = 'unknown'` and `suppressDialog_LEGACY = true`. In this case, we would downlevel the error to a warning. ## What's the fix? Change the default settings for the warning filter. ## What's the root cause? Bad configuration combinations in a fragile system that needs cleaned up, and really really bad testing practices with excessive mocking and snapshot testing (I can say that, I wrote the tests) ## How could it have been caught? It was, but I turned off the integration tests while landing the component stack changes because of mismatches between flags internally and in OSS, and never turned them back on.

React Native

React Native brings React's declarative UI framework to iOS and Android. With React Native, you use native UI controls and have full access to the native platform.
- Declarative. React makes it painless to create interactive UIs. Declarative views make your code more predictable and easier to debug.
- Component-Based. Build encapsulated components that manage their state, then compose them to make complex UIs.
- Developer Velocity. See local changes in seconds. Changes to JavaScript code can be live reloaded without rebuilding the native app.
- Portability. Reuse code across iOS, Android, and other platforms.
React Native is developed and supported by many companies and individual core contributors. Find out more in our ecosystem overview.

📋 Requirements
React Native apps may target iOS 13.4 and Android 6.0 (API 23) or newer. You may use Windows, macOS, or Linux as your development operating system, though building and running iOS apps is limited to macOS. Tools like Expo can be used to work around this.
🎉 Building your first React Native app
Follow the Getting Started guide. The recommended way to install React Native depends on your project. Here you can find short guides for the most common scenarios:
📖 Documentation
The full documentation for React Native can be found on our website.
The React Native documentation discusses components, APIs, and topics that are specific to React Native. For further documentation on the React API that is shared between React Native and React DOM, refer to the React documentation.
The source for the React Native documentation and website is hosted on a separate repo, @facebook/react-native-website.
🚀 Upgrading
Upgrading to new versions of React Native may give you access to more APIs, views, developer tools, and other goodies. See the Upgrading Guide for instructions.
React Native releases are discussed in this discussion repo.
