Difference between RN's and DT's SyntheticEvent type

[alloy]

In RN’s upstream type, most of the properties are Maybe types. Whereas in DT’s React type they are all required properties. This means that a value with RN’s type cannot be assigned to a target that expects DT’s type.

I only came across 1 such case in Artsy’s codebase, which I solved locally with a utility type that removes all the Maybe variants. It is unclear if this issue structurally applies to RN projects or is more of an issue with e.g. Formik relying on HTML event types.
