Steps to reproduce

Use boolean props in a typescript component

What is expected?

Boolean props should have type boolean, as their default default value is false

What is actually happening?

All non-required props without a default value are T | undefined

component.test-d.ts uses required: true to strip the undefined, but this is incorrect as boolean props aren't necessarily required. There are no checks for non-required boolean props.

Changing RequiredKeys to

type RequiredKeys<T> = {
  [K in keyof T]: T[K] extends { required: true } | { default: any } | BooleanConstructor | { type: BooleanConstructor } ? K : never
}[keyof T]

fixes it but seems wrong as they aren't actually required. default is in there already so whatever.

Yet another reproduction

What is expected? The default value specification at L 33 could be omitted.

What is actually happening? If the default value at L 33 was deleted, the computed below shows that the overload not match.

I'm also having a lot of problems with props in TypeScript.
