Catch some native crashes in Native UI Components in componentDidCatch

[punksta]

Introduction

Hello,

Sometimes I get native crashes in core and third party Native UI Components.
for example:

• some of the style prop validation happens in native code and сonsequently we can get run-time type mismatch error when we are using string ("1.0") when number (1.0) was expected.
• Animated.interpolate inputRange should be monotonic increasing number sequence. So when its values are calculated in runtime, you can get a runtime crash if your range is not right.
• other things related to props update in native code

The Core of It

I was thinking maybe it would be useful to be able to catch these native errors in componentDidCatch to hide a broken component. I know there are global error handlers for react-native, but my point only about Native UI Components errors.

thoughts about implementation

• Some errors can be catched by wrapping prop update native functions into try {} catch {} before invoking. That will work only for errors in current thread and current event. So delayed and asynchronous code will cause native crash anyway.
