Description

Adds TypeScript types definitions.
See also: #78

Test plan

The TS types are correctly picked up when importing Gesture Handlers inside *.ts file:

I think this needs to be added to "files" section too

@krzysztofciombor thanks for the typings!

It works if I import like this: import { Swipeable } from 'react-native-gesture-handler'
But not if I import like this: import Swipeable from 'react-native-gesture-handler/Swipeable'

Also maybe we should add types for the instances too, if possible?
E.g. I can call swipeableRef.close() and other methods but that doesn't autocomplete.

#87 should fix it

I get this on RectButton and don't know why:

[ts] Property 'style' does not exist on type 'IntrinsicAttributes & IntrinsicClassAttributes<RectButton> & Readonly<{ children?: ReactNode; }> ...'.
(JSX attribute) style: ((number & {
    __registeredStyleBrand: ViewStyle | TextStyle | ImageStyle;
}) | {
    backgroundColor: string;
    width: number | undefined;
})[]
